Health Insurance Reform: Security Standards


AGENCY: Centers for Medicare & Medicaid Services (CMS), HHS.


ACTION: Final rule.


-----------------------------------------------------------------------


SUMMARY: This final rule adopts standards for the security of 
electronic protected health information to be implemented by health 
plans, health care clearinghouses, and certain health care providers. 
The use of the security standards will improve the Medicare and 
Medicaid programs, and otherFederal health programs and private health 
programs, and the effectiveness and efficiency of the health care 
industry in general by establishing a level of protection for certain 
electronic health information. This final rule implements some of the 
requirements of the Administrative Simplification subtitle of the 
Health Insurance Portability andAccountability Act of 1996 (HIPAA).


DATES: Effective Date: These regulations are effective on April 21, 
2003.
    Compliance Date: Covered entities, with the exception of small 
health plans, must comply with the requirements of this final rule by 
April 21, 2005. Small health plans must comply with the requirements of 
this final rule by April 21, 2006.

I. Background


    The Department of Health and Human Services (HHS) Medicare Program, 
other Federal agencies operating health plans or providing health care, 
State Medicaid agencies, private health plans, health care providers, 
and health care clearinghouses must assure their customers (for 
example, patients, insured individuals, providers, and health plans) 
that the integrity, confidentiality, and availability of electronic 
protected health information they collect, maintain, use, or transmit 
is protected. The confidentiality of health information is threatened 
not only by the risk of improper access to stored information, but also 
by the risk of interception during electronic transmission of the 
information. The purpose of this final rule is to adopt national 
standards for safeguards to protect the confidentiality, integrity, and 
availability of electronic protected health information. Currently, no 
standard measures exist in the health care industry that address all 
aspects of the security of electronic health information while it is 
being stored or during the exchange of that information between 
entities.
    This final rule adopts standards as required under title II, 
subtitle F, sections 261 through 264 of the Health Insurance 
Portability and Accountability Act of 1996 (HIPAA), Pub. L. 104-191. 
These standards require measures to be taken to secure this information 
while in the custody of entities covered by HIPAA (covered entities) as 
well as in transit between covered entities and from covered entities 
to others.
    The Congress included provisions to address the need for 
safeguarding electronic health information and other administrative 
simplification issues in HIPAA. In subtitle F of title II of that law, 
the Congress added to title XI of the Social Security Act a new part C, 
entitled ``Administrative Simplification'' (hereafter, we refer to the 
Social Security Act as ``the Act''; we refer to the other laws cited in 
this document by their names). The purpose of subtitle F is to improve 
the Medicare program under title XVIII of the Act, the Medicaid program 
under title XIX of the Act, and the efficiency and effectiveness of the 
health care system, by encouraging the development of a health 
information system through the establishment of standards and 
requirements to enable the electronic exchange of certain health 
information.
    Part C of title XI consists of sections 1171 through 1179 of the 
Act. These sections define various terms and impose requirements on 
HHS, health plans, health care clearinghouses, and certain health care 
providers. These statutory sections are discussed in the Transactions 
Rule, at 65 FR 50312, on pages 50312 through 50313, and in the final 
rules adopting Standards for Privacy of Individually Identifiable 
Health Information, published on December 28, 2000 at 65 FR 82462 
(Privacy Rules), on pages 82470 through 82471, and on August 14, 2002 
at 67 FR 53182. The reader is referred to those discussions.
    Section 1173(d) of the Act requires the Secretary of HHS to adopt 
security standards that take into account the technical capabilities of 
record systems used to maintain health information, the costs of 
security measures, the need to train persons who have access to health 
information, the value of audit trails in computerized record systems, 
and the needs and capabilities of small health care providers and rural 
health care providers. Section 1173(d) of the Act also requires that 
the standards ensure that a health care clearinghouse, if part of a 
larger organization, has policies and security procedures that isolate 
the activities of the clearinghouse with respect to processing 
information so as to prevent unauthorized access to health information 
by the larger organization. Section 1173(d) of the Act provides that 
covered entities that maintain or transmit health information are 
required to maintain reasonable and appropriate administrative, 
physical, and technical safeguards to ensure the integrity and 
confidentiality of the information and to protect against any 
reasonably anticipated threats or hazards to the security or integrity 
of the information and unauthorized use or disclosure of the 
information. These safeguards must also otherwise ensure compliance 
with the statute by the officers and employees of the covered entities.


II. General Overview of the Provisions of the Proposed Rule


    On August 12, 1998, we published a proposed rule (63 FR 43242) to 
establish a minimum standard for security of electronic health 
information. We proposed that the standard would require the 
safeguarding of all electronic health information by covered entities. 
The proposed rule also proposed a


[[Page 8335]]


standard for electronic signatures. This final rule adopts only 
security standards. All comments concerning the proposed electronic 
signature standard, responses to these comments, and a final rule for 
electronic signatures will be published at a later date. A detailed 
discussion of the provisions of the August 12, 1998 proposed rule can 
be found at 63 FR 43245 through 43259.
    We originally proposed to add part 142, entitled ``Administrative 
Requirements,'' to title 45 of the Code of Federal Regulations (CFR). 
It has now been determined that this material will reside in subchapter 
C of title 45, consisting of parts 160, 162, and 164. Subpart A of part 
160 contains the general provisions applicable to all the 
Administrative Simplification rules; other subparts of part 160 will 
contain other requirements applicable to all standards. Part 162 
contains the standards for transactions and code sets and will contain 
the identifier standards. Part 164 contains the standards relating to 
privacy and security. Subpart A of part 164 contains general provisions 
applicable to part 164; subpart E contains the privacy standards. 
Subpart C of part 164, which is adopted in this final rule, adopts 
standards for the security of electronic protected health information.


III. Analysis of, and Responses to, Public Comments on the Proposed 
Rule


    We received approximately 2,350 timely public comments on the 
August 12, 1998 proposed rule. The comments came from professional 
associations and societies, health care workers, law firms, health 
insurers, hospitals, and private individuals. We reviewed each 
commenter's letter and grouped related comments. Some comments were 
identical. After associating like comments, we placed them in 
categories based on subject matter or based on the section(s) of the 
regulations affected and then reviewed the comments.
    In this section of the preamble, we summarize the provisions of the 
proposed regulations, summarize the related provisions in this final 
rule, and respond to comments received concerning each area.
    It should be noted that the proposed Security Rule contained 
multiple proposed ``requirements'' and ``implementation features.'' In 
this final rule, we replace the term ``requirement'' with ``standard.'' 
We also replace the phrase ``implementation feature'' with 
``implementation specification.'' We do this to maintain consistency 
with the use of those terms as they appear in the statute, the 
Transactions Rule, and the Privacy Rule. Within the comment and 
response portion of this final rule, for purposes of continuity, 
however, we use ``requirement'' and ``implementation feature'' when we 
are referring specifically to matters from the proposed rule. In all 
other instances, we use ``standard'' and ``implementation 
specification.''
    The proposed rule would require that each covered entity (as now 
described in Sec.  160.102) engaged in the electronic maintenance or 
transmission of health information pertaining to individuals assess 
potential risks and vulnerabilities to such information in its 
possession in electronic form, and develop, implement, and maintain 
appropriate security measures to protect that information. Importantly, 
these measures would be required to be documented and kept current.
    The proposed security standard was based on three basic concepts 
that were derived from the Administrative Simplification provisions of 
HIPAA. First, the standard should be comprehensive and coordinated to 
address all aspects of security. Second, it should be scalable, so that 
it can be effectively implemented by covered entities of all types and 
sizes. Third, it should not be linked to specific technologies, 
allowing covered entities to make use of future technology 
advancements.
    The proposed standard consisted of four categories of requirements 
that a covered entity would have to address in order to safeguard the 
integrity, confidentiality, and availability of its electronic health 
information pertaining to individuals: administrative procedures, 
physical safeguards, technical security services, and technical 
mechanisms. The implementation features described the requirements in 
greater detail when that detail was needed. Within the four categories, 
the requirements and implementation features were presented in 
alphabetical order to convey that no one item was considered to be more 
important than another.
    The four proposed categories of requirements and implementation 
features were depicted in tabular form along with the electronic 
signature standard in a combined matrix located at Addendum 1. We also 
provided a glossary of terms, at Addendum 2, to facilitate a common 
understanding of the matrix entries, and at Addendum 3, we mapped 
available existing industry standards and guidelines to the proposed 
security requirements.


A. General Issues


    The comment process overwhelmingly validated our basic assumptions 
that the entities affected by this regulation are so varied in terms of 
installed technology, size, resources, and relative risk, that it would 
be impossible to dictate a specific solution or set of solutions that 
would be useable by all covered entities. Many commenters also 
supported the concept of technological neutrality, which would afford 
them the flexibility to select appropriate technology solutions and to 
adopt new technology over time.
1. Security Rule and Privacy Rule Distinctions
    As many commenters recognized, security and privacy are 
inextricably linked. The protection of the privacy of information 
depends in large part on the existence of security measures to protect 
that information. It is important that we note several distinct 
differences between the Privacy Rule and the Security Rule.
    The security standards below define administrative, physical, and 
technical safeguards to protect the confidentiality, integrity, and 
availability of electronic protected health information. The standards 
require covered entities to implement basic safeguards to protect 
electronic protected health information from unauthorized access, 
alteration, deletion, and transmission. The Privacy Rule, by contrast, 
sets standards for how protected health information should be 
controlled by setting forth what uses and disclosures are authorized or 
required and what rights patients have with respect to their health 
information.
    As is discussed more fully below, this rule narrows the scope of 
the information to which the safeguards must be applied from that 
proposed in the proposed rule, electronic health information pertaining 
to individuals, to protected health information in electronic form. 
Thus, the scope of information covered in this rule is consistent with 
the Privacy Rule, which addresses privacy protections for ``protected 
health information.'' However, the scope of the Security Rule is more 
limited than that of the Privacy Rule. The Privacy Rule applies to 
protected health information in any form, whereas this rule applies 
only to protected health information in electronic form. It is true 
that, under section 1173(d) of the Act, the Secretary has authority to 
cover ``health information,'' which, by statute, includes information 
in other than electronic form. However, because the proposed rule 
proposed to cover only health information in electronic form, we do not 
include security standards for health information in non-electronic 
form in this final rule.


[[Page 8336]]


    We received a number of comments that pertained to privacy issues. 
These issues were considered in the development of the Privacy Rule and 
many of these comments were addressed in the preamble of the Privacy 
Rule. Therefore, we are referring the reader to that document for a 
discussion of those issues.
2. Level of Detail
    We solicited comments as to the level of detail expressed in the 
required implementation features; that is, we specifically wanted to 
know whether commenters believe the level of detail of any proposed 
requirement went beyond what is necessary or appropriate. We received 
numerous comments expressing the view that the security standards 
should not be overly prescriptive because the speed with which 
technology is evolving could make specific requirements obsolete and 
might in fact deter technological progress. We have accordingly written 
the final rule to frame the standards in terms that are as generic as 
possible and which, generally speaking, may be met through various 
approaches or technologies.
3. Implementation Specifications
    In addition to adopting standards, this rule adopts implementation 
specifications that provide instructions for implementing those 
standards.
    However, in some cases, the standard itself includes all the 
necessary instructions for implementation. In these instances, there 
may be no corresponding implementation specification for the standard 
specifically set forth in the regulations text. In those instances, the 
standards themselves also serve as the implementation specification. In 
other words, in those instances, we are adopting one set of 
instructions as both the standard and the implementation specification. 
The implementation specification would, accordingly, in those instances 
be required.
    In this final rule, we adopt both ``required'' and ``addressable'' 
implementation specifications. We introduce the concept of 
``addressable implementation specifications'' to provide covered 
entities additional flexibility with respect to compliance with the 
security standards.
    In meeting standards that contain addressable implementation 
specifications, a covered entity will ultimately do one of the 
following: (a) Implement one or more of the addressable implementation 
specifications; (b) implement one or more alternative security 
measures; (c) implement a combination of both; or (d) not implement 
either an addressable implementation specification or an alternative 
security measure. In all cases, the covered entity must meet the 
standards, as explained below.
    The entity must decide whether a given addressable implementation 
specification is a reasonable and appropriate security measure to apply 
within its particular security framework. This decision will depend on 
a variety of factors, such as, among others, the entity's risk 
analysis, risk mitigation strategy, what security measures are already 
in place, and the cost of implementation. Based upon this decision the 
following applies:
    (a) If a given addressable implementation specification is 
determined to be reasonable and appropriate, the covered entity must 
implement it.
    (b) If a given addressable implementation specification is 
determined to be an inappropriate and/or unreasonable security measure 
for the covered entity, but the standard cannot be met without 
implementation of an additional security safeguard, the covered entity 
may implement an alternate measure that accomplishes the same end as 
the addressable implementation specification. An entity that meets a 
given standard through alternative measures must document the decision 
not to implement the addressable implementation specification, the 
rationale behind that decision, and the alternative safeguard 
implemented to meet the standard. For example, the addressable 
implementation specification for the integrity standard calls for 
electronic mechanisms to corroborate that data have not been altered or 
destroyed in an unauthorized manner (see 45 CFR 164.312(c)(2)). In a 
small provider's office environment, it might well be unreasonable and 
inappropriate to make electronic copies of the data in question. 
Rather, it might well be more practical and afford a sufficient 
safeguard to make paper copies of the data.
    (c) A covered entity may also decide that a given implementation 
specification is simply not applicable (that is, neither reasonable nor 
appropriate) to its situation and that the standard can be met without 
implementation of an alternative measure in place of the addressable 
implementation specification. In this scenario, the covered entity must 
document the decision not to implement the addressable specification, 
the rationale behind that decision, and how the standard is being met. 
For example, under the information access management standard, an 
access establishment and modification implementation specification 
reads: ``implement policies and procedures that, based upon the 
entity's access authorization policies, establish, document, review, 
and modify a user's right of access to a workstation, transaction, 
program, or process'' (45 CFR 164.308(a)(4)(ii)(c)). It is possible 
that a small practice, with one or more individuals equally responsible 
for establishing and maintaining all automated patient records, will 
not need to establish policies and procedures for granting access to 
that electronic protected health information because the access rights 
are equal for all of the individuals.
    a. Comment: A large number of commenters indicated that mandating 
69 implementation features would result in a regulation that is too 
burdensome, intrusive, and difficult to implement. These commenters 
requested that the implementation features be made optional to meet the 
requirements. A number of other commenters requested that all 
implementation features be removed from the regulation.
    Response: Deleting the implementation specifications would result 
in the standards being too general to understand, apply effectively, 
and enforce consistently. Moreover, a number of implementation 
specifications are so basic that no covered entity could effectively 
protect electronic protected health information without implementing 
them. We selected 13 of these mandatory implementation specifications 
based on (1) the expertise of Federal security experts and generally 
accepted industry practices and, (2) the recommendation for immediate 
implementation of certain technical and organizational practices and 
procedures described in Chapter 6 of For The Record: Protecting 
Electronic Health Information, a 1997 report by the National Research 
Council (NRC). These mandatory implementation specifications are 
referred to as required implementation specifications and are reflected 
in the NRC report's recommendations. Risk Analysis and Risk management 
are found in the NRC recommendation title System Assessment; Sanction 
Policy is required in the Sanctions recommendation; Information system 
Activity Review is discussed in Audit Trails; Response and Reporting 
circumstances.
    In addition, a number of voluntary national and regional 
organizations have been formed to address HIPAA implementation issues 
and to facilitate


[[Page 8337]]


communication among trading partners. These include the Strategic 
National Implementation Process (SNIP) developed under the auspices of 
the Workgroup for Electronic Data Interchange (WEDI), an organization 
named in the HIPAA statute to consult with the Secretary of HHS on 
HIPAA issues. Some of these organizations have developed white papers, 
tools, and recommended best practices addressing a number of HIPAA 
issues, including security. Covered entities may wish to examine these 
products to determine if they are relevant and useful in their own 
implementation efforts. A partial list of these organizations can be 
found at http://www.wedi/snip./org. We believe that these and other 
future industry-developed guidelines and/or models may provide valuable 
assistance to covered entities implementing these standards but must 
caution that HHS does not rate or endorse any such guidelines and/or 
models and the value of its content must be determine by the user.
    b. Comment: Many commenters asked us to develop guidelines and 
models to aid in complying with the Security Rule. Several commenters 
either offered to participate in the development of guidelines and 
models or suggested entities that should be invited to participate.
    Response: We agree that creation of compliance tools and guidelines 
for different business environments could assist covered entities to 
implement the HIPAA Security Rule. We plan to issue guidance documents 
after the publication of this final rule. However, it is critical for 
each covered entity to establish policies and procedures that address 
its own unique risks and circumstances.
    In addition, a number of voluntary national and regional 
organizations have been formed to address HIPAA implementation issues 
and to facilitate communication among trading partners. These include 
the Strategic National Implementation Process (SNIP) developed under 
the auspices of the Workgroup for Electronic Data Interchange (WEDI), 
an organization named in the HIPAA statute to consult with the 
Secretary of HHS on HIPAA issues. Some of these organizations have 
developed white papers, tools, and recommended best practices 
addressing a number of HIPAA issues, including security.
    Covered entities may wish to examine these products to determine if 
they are relevant and useful in their own implementation efforts. A 
partial list of these organizations can be found at http://www.snip.wedi.org.
 We believe that these and other future industry-
developed guidelines and/or models may provide valuable assistance to 
covered entities implementing these standards but must caution that HHS 
does not rate or endorse any such guidelines and/or models and the 
value of its content must be determined by the user.
4. Examples
    Comment: We received a number of comments that demonstrated 
confusion regarding the purpose of the examples of security solutions 
that were included throughout the proposed rule. Commenters stated that 
they could not, or did not wish to, adopt various security measures 
suggested in examples. Other commenters asked that we include 
additional options within the examples. Some commenters referred 
specifically to the example provided in the proposed rule demonstrating 
how a small or rural provider might comply with the standards. One 
commenter asked for clarification that the examples are not mandatory 
measures that are required to demonstrate compliance, but are merely 
meant as a guide when implementing the security standards. Another 
commenter expressed support for the use of examples to clarify the 
intent of text descriptions.
    Response: We wish to clarify that examples are used only as 
illustrations of possible approaches, and are included to serve as a 
springboard for ideas. The steps that a covered entity will actually 
need to take to comply with these regulations will be dependent upon 
its own particular environment and circumstances and risk assessment. 
The examples do not describe mandatory measures, nor do they represent 
the only, or even the best, way of achieving compliance. The most 
appropriate means of compliance for any covered entity can only be 
determined by that entity assessing its own risks and deciding upon the 
measures that would best mitigate those risks.


B. Applicability (Sec.  164.302)


    We proposed that the security standards would apply to health 
plans, health care clearinghouses, and to health care providers that 
maintain or transmit health information electronically. The proposed 
security standards would apply to all electronic health information 
maintained or transmitted, regardless of format (standard transaction 
or a proprietary format). No distinction would be made between internal 
corporate entity communication or communication external to the 
corporate entity. Electronic transmissions would include transactions 
using all media, even when the information is physically moved from one 
location to another using magnetic tape, disk, or other machine 
readable media. Transmissions over the Internet (wide-open), extranet 
(using Internet technology to link a business with information only 
accessible to collaborating parties), leased lines, dial-up lines, and 
private networks would be included. We proposed that telephone voice 
response and ``faxback'' systems (a request for information made via 
voice using a fax machine and requested information returned via that 
same machine as a fax) would not be included but we solicited comments 
on this proposed exclusion.
    This final rule simplifies the applicability statement greatly. 
Section 164.302 provides that the security standards apply to covered 
entities; the scope of the information covered is specified in Sec.  
164.306 (see the discussion under that section below regarding the 
changes and revisions to the scope of information covered).
    1. Comment: A number of commenters requested clarification of who 
must comply with the standards. The preamble and proposed Sec.  142.102 
and Sec.  142.302 stated: ``Each person described in section 1172(a) of 
the Act who maintains or transmits health information shall maintain 
reasonable and appropriate administrative, technical, and physical 
safeguards.'' Commenters suggested that this statement is in conflict 
with the law, which defines a covered entity as a health plan, a 
clearinghouse, or a health care provider that conducts certain 
transactions electronically. The commentors apparently did not realize 
that section 1172(a) of the Act contains the definition of covered 
entities.
    Response: Section 164.302 below makes the security standards 
applicable to ``covered entities.'' The term ``covered entity'' is 
defined at Sec.  160.103 as one of the following: (1) A health plan; 
(2) a health care clearinghouse; (3) a health care provider who 
transmits any health information in electronic form in connection with 
a transaction covered by part 162 of title 45 of the Code of Federal 
Regulations (CFR). The rationale for the use and the meaning of the 
term ``covered entity'' is discussed in the preamble to the Privacy 
Rule (65 FR 82476 through 82477).
    As that discussion makes clear, the standards only apply to health 
care providers who engage electronically in the transactions for which 
standards have been adopted.


[[Page 8338]]


    2. Comment: Several commenters recommended expansion of 
applicability, either to other specific entities, or to all entities 
involved in health care. Others wanted to know whether the standards 
apply to entities such as employers, public health organizations, 
medical schools, universities, research organizations, plan brokers, or 
non-EDI providers. One commenter asked whether the standards apply to 
State data organizations operating in capacities other than as plans, 
clearinghouses, or providers. Still other commenters stated that it was 
inappropriate to include physicians and other health care professionals 
in the same category as plans and clearinghouses, arguing that 
providers should be subject to different, less burdensome requirements 
because they already protect health information.
    Response: The statute does not cover all health care entities that 
transmit or maintain individually identifiable health information. 
Section 1172(a) of the Act provides that only health plans, health care 
clearinghouses, and certain health care providers (as discussed above) 
are covered. With respect to the comments regarding the difference 
between providers and plans/clearinghouses, we have structured the 
Security Rule to be scalable and flexible enough to allow different 
entities to implement the standards in a manner that is appropriate for 
their circumstances. Regarding the coverage of entities not within the 
jurisdiction of HIPAA, see the Privacy Rule at 82567 through 82571.
    3. Comment: One commenter asked whether the standards would apply 
to research organizations, both to those affiliated with health care 
providers and those that are not.
    Response: Only health plans, health care clearinghouses, and 
certain health care providers are required to comply with the security 
standards. Researchers who are members of a covered entity's work force 
may be covered by the security standards as part of the covered entity. 
See the definition of ``workforce'' at 45 CFR 160.103. Note, however, 
that a covered entity could, under appropriate circumstances, exclude a 
researcher or research division from its health care component or 
components (see Sec.  164.105(a)). Researchers who are not part of the 
covered entity's workforce and are not themselves covered entities are 
not subject to the standards.
    4. Comment: Several commenters stated that internal networks and 
external networks should be treated differently. One commenter asked 
for further clarification of the difference between what needs to be 
secured external to a corporation versus the security of data movement 
within an organization. Another stated that complying with the security 
standards for internal communications may prove difficult and costly to 
monitor and control. In contrast, one commenter stated that the 
existence of requirements should not depend on whether use of 
information is for internal or external purposes.
    Another commenter argued that the regulation goes beyond the intent 
of the law, and while communication of electronic information between 
entities should be covered, the law was never intended to mandate 
changes to an entity's internal automated systems. One commenter 
requested that raw data that are only for the internal use of a 
facility be excluded, provided that reasonable safeguards are in place 
to keep the raw data under the control of the facility.
    Response: Section 1173(d)(2) of the Act states: Each person 
described in section 1172(a) who maintains or transmits health 
information shall maintain reasonable and appropriate administrative, 
technical, and physical safeguards--(A) to ensure the integrity and 
confidentiality of the information; (B) to protect against any 
reasonably anticipated--(i) threats or hazards to the security or 
integrity of the information; and (ii) unauthorized uses or disclosures 
of the information; and (C) otherwise to ensure compliance with this 
part by the officers and employees of such person.
    This language draws no distinction between internal and external 
data movement. Therefore, this final rule covers electronic protected 
health information at rest (that is, in storage) as well as during 
transmission. Appropriate protections must be applied, regardless of 
whether the data are at rest or being transmitted. However, because 
each entity's security needs are unique, the specific protections 
determined appropriate to adequately protect information will vary and 
will be determined by each entity in complying with the standards (see 
the discussion below).
    5. Comment: Several commenters found the following statement in the 
proposed rule (63 FR 43245) at section II.A. confusing and asked for 
clarification: ``With the exception of the security standard, 
transmission within a corporate entity would not be required to comply 
with the standards.''
    Response: In the final Transactions Rule, we revised our approach 
concerning the transaction and code set exemptions, replacing this 
concept with other tests that determine whether a particular 
transaction is subject to those standards (see the discussion in the 
Transactions Rule at 65 FR 50316 through 50318). We also note that the 
Privacy Rule regulates a covered entity's use, as well as disclosure, 
of protected health information.
    6. Comment: One commenter stated that research would be hampered if 
proposed Sec.  142.306(a) applied. The commenter believes that research 
uses of health information should be excluded or the standard should be 
revised to allow appropriate flexibility for research depending on the 
risk to patients or subjects (for example, if the information is 
anonymous, there is no risk, and it would not be necessary to meet the 
security standards).
    Response: If electronic protected health information is de-
identified (as truly anonymous information would be), it is not covered 
by this rule because it is no longer electronic protected health 
information (see 45 CFR 164.502(d) and 164.514(a)). Electronic 
protected health information received, created, or maintained by a 
covered entity, or that is transmitted by covered entities, is covered 
by the security standards and must be protected. To the extent a 
researcher is a covered entity, the researcher must comply with these 
standards with respect to electronic protected health information. 
Otherwise, the conditions for release of such information to 
researchers is governed by the Privacy Rule. See, for example, 45 CFR 
164.512(i), 164.514(e) and 164.502(d). These standards would not apply 
to the researchers as such in the latter circumstances.
    7. Comment: One commenter asked to what extent individual patients 
are subject to the standards. For example, some telemedicine practices 
support the use of diagnostic systems in the patient's home, which can 
be used to conduct tests and send results to a remote physician. In 
other cases, patients may be responsible for the filing of insurance 
claims directly and will need the ability to verify facts, confirm 
receipt of claims, and so on. The commenter asked if it is the intent 
of the rule to include electronic transmission to or from the patient.
    Response: Patients are not covered entities and, thus, are not 
subject to these standards. With respect to transmissions from covered 
entities, covered entities must protect electronic protected health 
information when they transmit that information. See also the 
discussion of encryption in section III.G.

C. Transition to the Final Rule


    The proposed rule included definitions for a number of terms that 
have now already been promulgated as part of the Transactions Rule or 
the Privacy Rule. Comments related to the definitions of ``code set,'' 
``health care'' clearinghouse,'' ``health plan,'' ``health care 
provider,'' ``small health plan,'' ``standard'' and ``transaction,'' 
are addressed in the Transactions Rule at 65 FR 50319 through 50320. 
Comments concerning the definition of ``individually identifiable 
health information'' are discussed below, but are also addressed in the 
Privacy Rule at 65 FR 82611 through 82613. In addition, a few terms 
were redefined in the final Standards for Privacy of Individually 
Identifiable Health Information (67 FR 53182), issued on August 14, 
2002 (Privacy Modifications). Certain terms that were defined in the 
proposed rule are not used in the final rule because they are no longer 
necessary. Other terms defined in the proposed rule are defined within 
the explanation of the standards in the final rule and are discussed in 
the preamble discussions in Sec.  164.308 through Sec.  164.312.
    Definitions of terms relevant to the security standards now appear 
in the regulations text provisions as indicated below:
    Sec.  160.103: Definitions of the following terms relevant to this 
rule appear in Sec.  160.103: ``business associate,'' ``covered 
entity,'' ``disclosure,'' ``electronic media,'' ``electronic protected 
health information,'' ``health care,'' ``health care clearinghouse,'' 
``health care provider,'' ``health information,'' ``health plan,'' 
``individual,'' ``individually identifiable health information,'' 
``implementation specification,'' ``organized health care 
arrangement,'' ``protected health information,'' ``standard,'' ``use,'' 
and ``workforce.'' These terms were discussed in connection with the 
Transaction and Privacy Rules and with the exception of the terms 
``covered entity'' ``disclosure'' ``electronic protected health 
information,'' ``health information,'' ``individual,'' ``organized 
health care arrangement,'' ``protected health information,'' and 
``use,'' we will not discuss them in this document. We note that the 
definition of those terms are not changed in the final rule.
    Sec.  162.103: We have moved the definition of ``electronic media'' 
at Sec.  162.103 to Sec.  160.103 and have modified it to clarify that 
the term includes storage of information. The term ``electronic media'' 
is used in the definition of ``protected health information.'' Both the 
privacy and security standards apply to information ``at rest'' as well 
as to information being transmitted.
    We note that we have deleted the reference to Sec.  162.103 in 
paragraph (1)(ii) of the definition of ``protected health 
information,'' since both definitions, ``electronic media'' and 
``protected health information,'' have been moved to this section. 
Also, it is unnecessary, because the definitions of Sec.  160.103 apply 
to all of the rule in parts 160, 162, and 164.
    We have also clarified that the physical movement of electronic 
media from place to place is not limited to magnetic tape, disk, or 
compact disk. This clarification removes a restriction as to what is 
considered to be physical electronic media, thereby allowing for future 
technological innovation. We further clarified that transmission of 
information not in electronic form before the transmission, for 
example, paper or voice, is not covered by this definition.
    Sec.  164.103: The following term ``plan sponsor'' now appears in 
the new Sec.  164.103, which consists of definitions of terms common to 
both subpart C and subpart E (the privacy standards). This definition 
was moved, without substantive change, from Sec.  164.501 and has the 
meaning given to it in that section, and comments relating to this 
definition are discussed in connection with that section in the Privacy 
Rule at 65 FR 82607, 82611 through 82613, 82618 through 82622, and 
82629.
    Sec.  164.304: Definitions specifically applicable to the Security 
Rule appear in Sec.  164.304, and these are discussed below. These 
definitions are from, or derived from, currently accepted definitions 
in industry publications, such as, the International Organization for 
Standards (ISO) 7498-2 and the American Society for Testing and 
Materials (ASTM) E1762-95.
    The following terms in Sec.  164.304 are taken from the proposed 
rule text or the glossary in Addendum 2 of the proposed rule (63 FR 
43271), were not commented on, and/or are unchanged or have only minor 
technical changes for purposes of clarification and are not discussed 
below: ``access,'' ``authentication,'' ``availability,'' 
``confidentiality,'' ``encryption,'' ``password,'' and ``security.''
    Sec.  164.314: Four terms were defined in Sec.  164.504(a) of the 
Privacy Rule (``common control,'' ``common ownership,'' ``health care 
component,'' and ``hybrid entity''). Because these terms apply to both 
security and privacy, their definitions have been moved to Sec.  
164.103 without change. Those terms are discussed in the Privacy Rule 
at 65 FR 82502 through 82503 and at 67 FR 53203 through 53207.
1. Covered Entity (Sec.  160.103)
    Comment: One commenter asked if transcription services were covered 
entities. The question arose because transcription is often the first 
electronic or printed source of clinical information. Concern was 
expressed about the application of physical safeguard standards to the 
transcribers working for transcription companies or health care 
providers, either as employees or as independent contractors.
    Another commenter expressed concern that scalability was limited to 
only small providers. The commenter explained that Third Party 
Administrators (TPAs) allow claim processors to work at home. Some TPAs 
have noted that it would be impossible to comply with the security 
standards for home-based claims processors.
    Response: A covered entity's responsibility to implement security 
standards extends to the members of its workforce, whether they work at 
home or on-site. Because a covered entity is responsible for ensuring 
the security of the information in its care, the covered entity must 
include ``at home'' functions in its security process. While an 
independent transcription company or a TPA may not be covered entities, 
they will be a business associate of the covered entity because their 
activities fall under paragraph (1)(i)(a) of the definition of that 
term. For business associate provisions see proposed preamble section 
III.E.8. and Sec.  164.308(b)(1) and Sec.  164.314(c) of this final 
rule.
2. Health Care and Medical Care (Sec.  160.103)
    Comment: One commenter asked whether ``medical care,'' which is 
defined in the proposed rule, and ``health care,'' which is not, are 
synonymous.
    Response: The term ``medical care,'' as used in the proposed rule 
(63 FR 43242), was intended to be synonymous with ``health care.'' The 
term ldquo;medical care'' is not included in this final rule. It is, 
however, included in the definition of ``health plan,'' where its 
meaning is not synonymous with ``health care.'' For a full discussion 
of this issue and its resolution, see the Privacy Rule (65 FR 82578).


[[Page 8340]]


3. Health Information and Individually Identifiable Health Information 
160.103)
    We note that the definitions of ``health information'' and 
``individually identifiable health information'' remain unchanged from 
those published in the Transactions and Privacy Rules.
    a. Comment: A number of commenters asked that the definition of 
``health information'' be expanded to include information collected by 
additional entities. Several commenters wanted the definition to 
include health information collected, maintained, or transmitted by any 
entity, and one commenter suggested the inclusion of aggregated 
information not identifiable to an individual. Several commenters asked 
that eligibility information be excluded from the definition of 
information. Several commenters wanted the definition broadened to 
include demographics.
    Response: Our definition of health information is taken from the 
definition in section 1171(4) of the Act, which provides that health 
information relates to the health or condition of an individual, the 
provision of health care to an individual, or payment for the provision 
of health care to an individual. The statutory definition also 
specifies the entities by which health information is created or 
received. We note that, because ``individually identifiable health 
information'' is a subset of ``health information'' and by statute 
includes demographic information, ``health information'' necessarily 
includes demographic information. We think this is clear as a matter of 
statutory construction and does not require further regulatory change.
    b. Comment: Several commenters asked that we clarify the difference 
between ``health information'' and ``individually identifiable'' and 
``health information pertaining to an individual'' as used in the 
August 12, 1998 proposed rule (63 FR 43242). Additionally, commenters 
asked that we be more consistent in the use of these terms and 
recommended use of the term ``individually identifiable health 
information.''
    Two commenters stated that it is important to distinguish between 
``health information pertaining to an individual'' and ``individually 
identifiable health information,'' as in reporting statistics at 
various levels there will always be a need to bring forth information 
pertaining to an individual.
    One commenter recommended that the standards apply only to 
individually identifiable health information. Another stated that in 
Sec.  142.306(b) of the proposed rule, ``health information pertaining 
to an individual'' should be changed to ``individually identifiable 
health information,'' as nonidentifiable information can be used for 
utilization review and other purposes. As written, the regulation text 
could limit the ability to use data, for example, from a clearinghouse 
for compliance monitoring.
    Response: In general, we agree with these commenters, and note that 
these comments are largely mooted by the decision, reflected in Sec.  
164.306 below and discussed in section III.D.1. of this final rule, to 
cover only electronic protected health information in this final rule.
    c. Comment: Several commenters stated that the definition of 
``individually identifiable health information'' is not in the 
regulations and should be added.
    Response: We note that the definition of ``individually 
identifiable health information'' appears at Sec.  160.103, which 
applies to this final rule.
4. Protected Health Information (Sec.  160.103)
    This term is moved from Sec.  164.501 to Sec.  160.103 because it 
applies to both subparts C (security) and E (privacy). See 67 FR 53192 
through 531936 regarding the definition of ``protected health 
information.''
    Also, the term ``electronic media'' is included in paragraphs 
(1)(i) and (ii) of the definition of ``protected health information,'' 
as specified in this section.
    In addition, we added the definitions of ``covered functions,'' 
``plan sponsor,'' and ``Required by law'' to Sec.  164.103.
5. Breach (Sec.  164.304)
    Comment: One commenter asked that ``breach'' be defined.
    Response: The term ``breach'' has been deleted and therefore not 
defined. Instead, we define the term ``security incident,'' which 
better describes the types of situations we were referring to as 
breaches.
6. Facility (Sec.  164.304)
    This new term has been added as a result of changing the name of 
the ``physical access control'' standard to ``facility access 
control.'' This change was made based on comments indicating that the 
original term was not descriptive. We have defined the term 
``facility'' as the physical premises and interior and exterior of a 
building.
7. Security Incident (Sec.  164.304)
    Comment: We received comments asking that this term be defined.
    Response: This final rule defines ``Security incident'' in Sec.  
164.304 as ``the attempted or successful unauthorized access, use, 
disclosure, modification, or destruction of information or interference 
with system operations in an information system.''
8. System (Sec.  164.304)
    Comment: One commenter asked that ``system'' be defined.
    Response: This final rule defines ``system,'' in the context of an 
information system, in Sec.  164.304 as ``an interconnected set of 
information resources under the same direct management control that 
shares common functionality. A system normally includes hardware, 
software, information, data, applications, communications, and 
people.''
9. Workstation (Sec.  164.304)
    Comment: One commenter expressed concern that the use of the term 
``workstation'' implied limited applicability to fixed devices (such as 
terminals), excluding laptops and other portable devices.
    Response: We have added a definition of the term ``workstation'' to 
clarify that portable devices are also included. This final rule 
defines workstation as ``an electronic computing device, for example, a 
laptop or desktop computer, or any other device that performs similar 
functions, and electronic media stored in its immediate environment.''
10. Definitions Not Adopted
    Several definitions in the proposed regulations text and glossary 
are not adopted as definitions in the final rule: ``participant,'' 
``contingency plan,'' ``risk,'' ``role-based access control,'' and 
``user-based access control.'' The terms ``participant,'' ``role-based 
access control,'' and ``user-based access control'' are not used in 
this final rule and thus are not defined. ``Risk'' is not defined as 
its meaning is generally understood. While we do not define the term, 
we address ``contingency plan'' as a standard in Sec.  164.308(a)(7) 
below.
    a. Comment: We received comments requesting that we define the 
following terms: ``token'' and ``documentation.''
    Response: These terms were defined in Addendum 2 of the proposed 
rule. In this final rule, we do not adopt a definition for ``token'' 
because it is not used in the final rule. ``Documentation'' is 
discussed in Sec.  164.316 below.
    b. Comment: We received several comments that ``small'' and 
``rural'' should be defined as those terms apply


[[Page 8341]]


to providers. We received an equal number of comments stating that 
there is no need to define these terms. One commenter stated that 
definitions for these terms would be necessary only if special 
exemptions existed for small and rural providers. Several commenters 
suggested initiation of a study to determine limitations and potential 
barriers small and rural providers will have in implementing these 
regulations.
    Response: The statute requires that we address the needs of small 
and rural providers. We believe that we have done this through the 
provisions, which require the risk assessment and the response to be 
assessment based on the needs and capabilities of the entity. This 
scalability concept takes the needs of those providers into account and 
eliminates any need to define those terms.
    c. Comment: In the proposed rule, we proposed the following 
definition for the term ``Access control'': ``A method of restricting 
access to resources, allowing only privileged entities access. Types of 
access control include, among others, mandatory access control, 
discretionary access control, time-of-day, classification, and subject-
object separation.'' One commenter believed the proposed definition is 
too restrictive and requested revision of the definition to read: 
``Access control refers to a method of restricting access to resources, 
allowing access to only those entities which have been specifically 
granted the desired access rights.'' Another commenter wanted the 
definition expanded to include partitioned rule-based access control 
(PRBAC).
    Response: We agree with the commenter who suggested that the 
definition as proposed seemed too restrictive. In this case, as in many 
others, a number of commenters believed the examples given in the 
proposed rule provided the only acceptable compliance actions. As 
previously noted, in order to clarify that the examples listed were not 
to be considered all-inclusive, we have generalized the proposed 
requirements in this final rule. In this case, we have also generalized 
the requirements and placed the substantive provisions governing access 
control at Sec.  164.308(a)(4), Sec.  164.310(a)(1), and Sec.  
164.312(a)(1). With respect to PRBAC, the access control standard does 
not exclude this control, and entities should adopt it if appropriate 
to their circumstances.


D. General Rules (Sec.  164.306)


    In the proposed rule, we proposed to cover all health information 
maintained or transmitted in electronic form by a covered entity. We 
proposed to adopt, in Sec.  142.308, a nation-wide security standard 
that would require covered entities to implement security measures that 
would be technology-neutral and scalable, and yet integrate all the 
components of security (administrative procedures, physical safeguards, 
technical security services, and technical security mechanisms) that 
must be in place to preserve health information confidentiality, 
integrity, and availability (three basic elements of security). Since 
no comprehensive, scalable, and technology-neutral set of standards 
currently exists, we proposed to designate a new standard, which would 
define the security requirements to be fulfilled.
    The proposed rule proposed to define the security standard as a set 
of scalable, technology-neutral requirements with implementation 
features that providers, plans, and clearinghouses would have to 
include in their operations to ensure that health information 
pertaining to an individual that is electronically maintained or 
electronically transmitted remains safeguarded. The proposed rule would 
have required that each affected entity assess its own security needs 
and risks and devise, implement, and maintain appropriate security to 
address its own unique security needs. How individual security 
requirements would be satisfied and which technology to use would be 
business decisions that each entity would have to make.
    In the final rule we adopt this basic framework. In Sec.  164.306, 
we set forth general rules pertaining to the security standards. In 
paragraph (a), we describe the general requirements. Paragraph (a) 
generally reflects section 1173(d)(2) of the Act, but makes explicit 
the connection between the security standards and the privacy standards 
(see Sec.  164.306(a)(3)). In Sec.  164.306(a)(1), we provide that the 
security standards apply to all electronic protected health information 
the covered entity creates, receives, maintains, or transmits. In 
paragraph (b)(1), we provide explicitly for the scalability of this 
rule by discussing the flexibility of the standards, and paragraph 
(b)(2) of Sec.  164.306 discusses various factors covered entities must 
consider in complying with the standards.
    The provisions of Sec.  164.306(c) provide the framework for the 
security standards, and establish the requirement that covered entities 
must comply with the standards. The administrative, physical, and 
technical safeguards a covered entity employs must be reasonable and 
appropriate to accomplish the tasks outlined in paragraphs (1) through 
(4) of Sec.  164.306(a). Thus, an entity's risk analysis and risk 
management measures required by Sec.  164.308(a)(1) must be designed to 
lead to the implementation of security measures that will comply with 
Sec.  164.306(a).
    It should be noted that the implementation of reasonable and 
appropriate security measures also supports compliance with the privacy 
standards, just as the lack of adequate security can increase the risk 
of violation of the privacy standards. If, for example, a particular 
safeguard is inadequate because it routinely permits reasonably 
anticipated uses or disclosures of electronic protected health 
information that are not permitted by the Privacy Rule, and that could 
have been prevented by implementation of one or more security measures 
appropriate to the scale of the covered entity, the covered entity 
would not only be violating the Privacy Rule, but would also not be in 
compliance with Sec.  164.306(a)(3) of this rule.
    Paragraph (d) of Sec.  164.306 establishes two types of 
implementation specifications, required and addressable. It provides 
that required implementation specifications must be met. However, with 
respect to implementation specifications that are addressable, Sec.  
164.306(d)(3) specifies that covered entities must assess whether an 
implementation specification is a reasonable and appropriate safeguard 
in its environment, which may include consideration of factors such as 
the size and capability of the organization as well as the risk. If the 
organization determines it is a reasonable and appropriate safeguard, 
it must implement the specification. If an addressable implementation 
specification is determined not to be a reasonable and appropriate 
answer to a covered entity's security needs, the covered entity must do 
one of two things: implement another equivalent measure if reasonable 
and appropriate; or if the standard can otherwise be met, the covered 
entity may choose to not implement the implementation specification or 
any equivalent alternative measure at all. The covered entity must 
document the rationale behind not implementing the implementation 
specification. See the detailed discussion in section II.A.3.
    Paragraph (e) of Sec.  164.306 addresses the requirement for 
covered entities to maintain the security measures


[[Page 8342]]


implemented by reviewing and modifying the measures as needed to 
continue the provision of reasonable and appropriate protections, for 
example, as technology moves forward, and as new threats or 
vulnerabilities are discovered.
1. Scope of Health Information Covered by the Rule (Sec.  164.306(a))
    We proposed to cover health information maintained or transmitted 
by a covered entity in electronic form. We have modified, by narrowing, 
the scope of health information to be safeguarded under this rule from 
that which was proposed. The statute requires the privacy standards to 
cover individually identifiable health information. The Privacy Rule 
covers all individually identifiable information except for: (1) 
Education records covered by the Family and Educational Rights and 
Privacy Act (FERPA); (2) records described in 20 U.S.C. 
1232g(a)(4)(B)(iv); and (3) employment records. (see the Privacy Rule 
at 65 FR 82496. See also 67 FR 53191 through 53193). The scope of 
information covered in the Privacy Rule is referred to as ``protected 
health information.'' Based upon the comments we received, we align the 
requirements of the Security and Privacy Rules with regard to the scope 
of information covered, in order to eliminate confusion and ease 
implementation. Thus, this final rule requires protection of the same 
scope of information as that covered by the Privacy Rule, except that 
it only covers that information if it is in electronic form.
    We note that standards for the security of all health information 
or protected health information in nonelectronic form may be proposed 
at a later date.
    a. Comment: One commenter stated that the rule should apply to 
aggregate information that is not identifiable to an individual. In 
contrast, another commenter asked that health information used for 
statistical analysis be exempted if the covered entity may reasonably 
expect that the removed information cannot be used to re-identify an 
individual.
    Response: As a general proposition, any electronic protected health 
information received, created, maintained, or transmitted by a covered 
entity is covered by this final rule. We agree with the second 
commenter that certain information, from which identifiers have been 
stripped, does not come within the purview of this final rule. 
Information that is de-identified, as defined in the Privacy Rule at 
Sec.  164.502(d) and Sec.  164.514(a), is not ``individually 
identifiable'' within the meaning of these rules and, thus, does not 
come within the definition of ``protected health information.'' It 
accordingly is not covered by this final rule. For a full discussion of 
the issues of de-identification and re-identification of individually 
identifiable health information see 65 FR 82499 and 82708 through 82712 
and 67 FR 53232 through 53234.
    b. Comment: Several commenters asked whether systems that determine 
eligibility of clients for insurance coverage under broad categories 
such as medical coverage groups are considered health information. One 
commenter asked that we specifically exclude eligibility information 
from the standards.
    Response: We cannot accept the latter suggestion. Eligibility 
information will typically be individually identifiable, and much 
eligibility information will also contain health information. If the 
information is ``individually identifiable'' and is ``health 
information,'' (with three very specific exceptions noted in the 
general discussion above) and it is in electronic form, it is covered 
by the security standards if maintained or transmitted by a covered 
entity.
    c. Comment: Several commenters requested clarification as to 
whether the standards apply to identifiable health information in paper 
form. Some commenters believed the rule should be applicable to paper; 
others argued that it should apply to all confidential, identifiable 
health information.
    Response: While we agree that protected health information in paper 
or other form also should have appropriate security protections, the 
proposed rule proposing the security standards proposed to apply those 
standards to health information in electronic form only. We are, 
accordingly, not extending the scope in this final rule.
    We may establish standards to secure protected health information 
in other media in a future rule, in accordance with our statutory 
authority to do so. See discussion, supra, responding to a comment on 
the definition of ``health information'' and ``individually 
identifiable health information.''
    d. Comment: The proposed rule would have excluded ``telephone voice 
response'' and ``faxback'' systems from the security standards, and we 
specifically solicited comments on that issue. A number of commenters 
agreed that telephone voice response and faxback should be excluded 
from the regulation, suggesting that the privacy standards rather than 
the security standards should apply. Others wanted those systems 
included, on the grounds that inclusion is necessary for consistency 
and in keeping with the intent of the Act. Still others specifically 
wanted personal computer-fax transmissions included. One commenter 
asked for clarification of when we would cover faxes, and another 
commenter asked why we were excluding them. Several commenters 
suggested that the other security requirements provide for adequate 
security of these systems.
    Response: In light of these comments, we have decided that 
telephone voice response and ``faxback'' (that is, a request for 
information from a computer made via voice or telephone keypad input 
with the requested information returned as a fax) systems fall under 
this rule because they are used as input and output devices for 
computers, not because they have computers in them. Excluding these 
features would provide a huge loophole in any system concerned with 
security of the information contained and/or processed therein. It 
should be noted that employment of telephone voice response and/or 
faxback systems will generally require security protection by only one 
of the parties involved, and not the other. Information being 
transmitted via a telephone (either by voice or a DTMP tone pad) is not 
in electronic form (as defined in the first paragraph of the definition 
of ``electronic media'') before transmission and therefore is not 
subject to the Security Rule. Information being returned via a 
telephone voice response system in response to a telephone request is 
data that is already in electronic form and stored in a computer. This 
latter transmission does require protection under the Security Rule.
    Although most recently made electronic devices contain 
microprocessors (a form of computer) controlled by firmware (an 
unchangeable form of computer program), we intend the term ``computer'' 
to include only software programmable computers, for example, personal 
computers, minicomputers, and mainframes. Copy machines, fax machines, 
and telephones, even those that contain memory and can produce multiple 
copies for multiple people are not intended to be included in the term 
``computer.'' Therefore, because ``paper-to-paper'' faxes, person-to-
person telephone calls, video teleconferencing, or messages left on 
voice-mail were not in electronic form before the transmission, those 
activities are not covered by this rule. See also the definition of 
``electronic media'' at Sec.  160.103.

    We note that this guidance differs from the guidance regarding the 
applicability of the Transactions Rule to faxback and voice response 
systems. HHS has stated that faxback and voice response systems are not 
required to follow the standards mandated in the Transactions Rule. 
This new guidance refers only to this rule.
    e. Comment: One commenter asked whether there is a need to 
implement special security practices to address the shipping and 
receiving of health information and asked that we more fully explain 
our expectations and solutions in the final rules.
    Response: If the handling of electronic protected health 
information involves shipping and receiving, appropriate measures must 
be taken to protect the information. However, specific solutions are 
not provided within this rule, as discussed in section III.A.3 of this 
final rule. The device and media controls standard under Sec.  
164.310(d)(1) addresses this situation.
    f. Comment: One commenter wanted the ``HTML'' statement reworded to 
eliminate a specific exemption for HTML from the regulation.
    Response: The Transactions Rule did not adopt the proposed 
exemption for HTML. The use of HTML or any other electronic protocol is 
not exempt from the security standards. Generally, if protected health 
information is contained in any form of electronic transmission, it 
must be appropriately safeguarded.
    g. Comment: One commenter asked to what degree ``family history'' 
is considered health information under this rule and what protections 
apply to family members included in a patient's family history.
    Response: Any health-related ``family history'' contained in a 
patient's record that identifies a patient, including a person other 
than the patient, is individually identifiable health information and, 
to the extent it is also electronic protected health information, must 
be afforded the security protections.
    h. Comment: Two commenters asked that the rule prohibit re-
identification of de-identified data. In contrast, several commenters 
asked that we identify a minimum list or threshold of specific re-
identification data elements (for example, name, city, and ZIP) that 
would fall under this final rule so that, for example, the rule would 
not affect numerous systems, for example, network adequacy and 
population-based clinical analysis databases. One commenter asked that 
we establish a means to use re-identified information if the entity 
already has access to the information or is authorized to have access.
    Response: The issue of re-identification is addressed in the 
Privacy Rule at Sec.  164.502(d) and Sec.  164.514(c). The reader is 
referred to those sections and the related discussion in the preamble 
to the Privacy Rule (65 FR 82712) and the preamble to the Privacy 
Modifications (67 FR 53232 through 53234) for a full discussion of the 
issues of re-identification. We note that once information in the 
possession (or constructive possession) of a covered entity is re-
identified and meets the definition of electronic protected health 
information, the security standards apply.
2. Technology-Neutral Standards
    Comment: Many commenters expressed support for our efforts to 
develop standards for the security of health information. A number of 
comments were made in support of the technology-neutral approach of the 
proposed rule. For example, one commenter stated, ``By avoiding 
prescription of the specific technologies health care entities should 
use to meet the law's requirements, you are opening the door for 
industry to apply innovation. Technologies that don't currently exist 
or are impractical today could, in the near future, enhance health 
information security while minimizing the overall cost.'' Several other 
commenters stated that the requirements should be general enough to 
withstand changes to technology without becoming obsolete. One 
commenter anticipates no problems with meeting the standards.
    In contrast, one commenter suggested that whenever possible, 
specific technology recommendations should provide sufficient detail to 
promote systems interoperability and decrease the tendency toward 
adoption of multiple divergent standards. Several commenters stated 
that by letting each organization determine its own rules, the rules 
impose procedural burdens without any substantive benefit to security.
    Response: The overwhelming majority of comments supported our 
position. We do not believe it is appropriate to make the standards 
technology-specific because technology is simply moving too fast, for 
example, the increased use and sophistication of internet-enabled hand 
held devices. We believe that the implementation of these rules will 
promote the security of electronic protected health information by (1) 
providing integrity and confidentiality; (2) allowing only authorized 
individuals access to that information; and (3) ensuring its 
availability to those authorized to access the information. The 
standards do not allow organizations to make their own rules, only 
their own technology choices.
3. Miscellaneous Comments
    a. Comment: Some commenters stated that the requirements and 
implementation features set out in the proposed rule were not specific 
enough to be considered standards, and that the actual standards are 
delegated to the discretion of the covered entities, at the expense of 
medical record privacy. Several commenters stated that it was 
inappropriate to balance the interests of those seeking to use 
identifiable medical information without patient consent against the 
interest of patients. Several other commenters believe that allowing 
covered entities to make their own decisions about the adequacy and 
balance of security measures undermined patient confidentiality 
interests, and stated that the proposed rule did not appear to 
adequately consider patient concerns and viewpoints.
    Response: Again, the overwhelming majority of commenters supported 
our approach. This final rule sets forth requirements with which 
covered entities must comply and labels those requirements as standards 
and implementation specifications. Adequate implementation of this 
final rule by covered entities will ensure that the electronic 
protected health information in a covered entity's care will be as 
protected as is feasible for that entity.
    We disagree that covered entities are given complete discretion to 
determine their security polices under this rule, resulting in effect, 
in no standards. While cost is one factor a covered identity may 
consider in determining whether to implement a particular 
implementation specification, there is nonetheless a clear requirement 
that adequate security measures be implemented, see 45 CFR 164.306(b). 
Cost is not meant to free covered entities from this responsibility.
    b. Comment: Several commenters requested we withdraw the 
regulations, citing resource shortages due to Y2K preparation, upcoming 
privacy legislation, and/or the ``excessive micro-management'' 
contained in the rules. One commenter stated that, to insurers, these 
rules were onerous, not necessary, and not justified as cost-effective, 
as they already have effective practices for computer security and are 
subject to rigorous State laws for the safeguarding of health 
information. Another


[[Page 8344]]


commenter stated that these rules would adversely affect a provider's 
practice environment.
    Response: The HIPAA statute requires us to promulgate a rule 
adopting security standards for health information. Resource concerns 
due to Y2K should no longer be an issue. Covered entities will have 2 
years (or, in the case of small health plans, 3 years) from the 
adoption of this final rule in which to comply. Concerns relative to 
effective and compliance dates and the Privacy Rule are discussed under 
Sec.  164.318, Compliance dates for initial implementation, below and 
at 65 FR 82751 through 82752.
    We disagree that these standards will adversely affect a provider's 
practice environment. The scalability of the standards allows each 
covered entity to implement security protections that are appropriate 
to its specific needs, risks, and environments. These protections are 
necessary to maintain the confidentiality, integrity, and availability 
of patient data. A covered entity that lacks adequate protections risks 
inadvertent disclosure of patient data, with resulting loss of public 
trust, and potential legal action. For example, a covered entity with 
poor facility access controls and procedures would be susceptible to 
hacking of its databases. A provider with appropriate security 
protections already in place would only need to ensure that the 
protections are documented and are reassessed periodically to ensure 
that they continue to be appropriate and are actually being 
implemented. Our decision to classify many implementation 
specifications as addressable, rather than mandatory, provides even 
more flexibility to covered entities to develop cost-effective 
solutions. We believe that insurers who already have effective security 
programs in place will have met many of the requirements of this 
regulation.
    c. Comment: One commenter believes the rule is arbitrary and 
capricious in its requirements without any justification that they will 
significantly improve the security of medical records and with the 
likelihood that their implementation may actually increase the 
vulnerability of the data. The commenter noted that the data backup 
requirements increase access to data and that security awareness 
training provides more information to employees.
    Response: The standards are based on generally accepted security 
procedures, existing industry standards and guidelines, and 
recommendations contained in the National Research Council's 1997 
report For The Record: Protecting Electronic Health Information, 
Chapter 6. We also consulted extensively with experts in the field of 
security throughout the health care industry. The standards are 
consistent with generally accepted security principles and practices 
that are already in widespread use.
    Data backup need not result in increased access to that data. 
Backups should be stored in a secure location with controlled access. 
The appropriate secure location and access control will vary, based 
upon the security needs of the covered entity. For example, a procedure 
as simple as locking backup diskettes in a safe place and restricting 
who has access to the key may be suitable for one entity, whereas 
another may need to store backed-up information off-site in a secure 
computer facility. The information provided in security awareness 
training heightens awareness of security anomalies and helps to prevent 
security incidents.
    d. Comment: Several commenters suggested that the proposed rule 
appears to reflect the Medicare program's perspective on security risks 
and solutions, and that it should be noted that not all industry 
segments share all the same risks as Medicare. One commenter stated 
that as future proposed rules are drafted, we should solicit input from 
those most significantly affected, for example, providers, plans, and 
clearinghouses.
    Others stated that Medicaid agencies were not sufficiently involved 
in the discussions and debate. Still another stated that States would 
be unable to perform some basic business functions if all the standards 
are not designed to meet their needs.
    Response: We believe that the standards are consistent with common 
industry practices and equitable, and that there has been adequate 
consultation with interested parties in the development of the 
standards. These standards are the result of an intensive process of 
public consultation. We consulted with the National Uniform Billing 
Committee, the National Uniform Claim Committee, the American Dental 
Association, and the Workgroup for Electronic Data Interchange, in the 
course of developing the proposed rule. Those organizations were 
specifically named in the Act to advise the Secretary, and their 
membership is drawn from the full spectrum of industry segments. In 
addition, the National Committee on Vital and Health Statistics 
(NCVHS), an independent advisory group to the Secretary, held numerous 
public hearings to obtain the views of interested parties. Again, many 
segments of the health care industry, including provider groups, health 
plans, clearinghouses, vendors, and government programs participated 
actively. The NCVHS developed recommendations to the Secretary, which 
were relied upon as we developed the proposed rule. Finally, we note 
that the opportunity to comment was available to all during the public 
comment period.
    e. Comment: One commenter stated that there is a need to ensure the 
confidentiality of risk analysis information that may contain sensitive 
information.
    Response: The information included in a risk analysis would not be 
subject to the security standards if it does not include electronic 
protected health information. We agree that risk analysis data could 
contain sensitive information, just as other business information can 
be sensitive. Covered entities may wish to develop their own business 
rules regarding access to and protections for risk analysis data.
    f. Comment: One commenter expressed concern over the statement in 
the preamble of the proposed rule (63 FR 43250) that read: ``No one 
item is considered to be more important than another.'' The commenter 
suggested that security management should be viewed as most critical 
and perhaps what forms the foundation for all other security actions.
    Response: The majority of comments received on this subject 
requested that we prioritize the standards. In response, we have 
regrouped the standards and implementation specifications in what we 
believe is a logical order within each of three categories: 
``Administrative safeguards,'' ``Physical safeguards,'' and ``Technical 
safeguards.'' In this final rule, we order the standards in such a way 
that the ``Security management process'' is listed first under the 
``Administrative safeguards'' section, as we believe this forms the 
foundation on which all of the other standards depend. The 
determination of the specific security measures to be implemented to 
comply with the standards will, in large part, be dependent upon 
completion of the implementation specifications within the security 
management process standard (see Sec.  164.308(a)(1)). We emphasize, 
however, that an entity implementing these standards may choose to 
implement them in any order, as long as the standards are met.
    g. Comment: One commenter stated that there is a need for 
requirements concerning organizational practices (for example, 
education, training, and security and confidentiality policies), as


[[Page 8345]]


well as technical practices and procedures.
    Response: We agree. Section 164.308 of this final rule describes 
administrative safeguards that address these topics. Section 164.308 
requires covered entities to implement standards and required 
implementation specifications, as well as consider and implement, when 
appropriate and reasonable, addressable implementation specifications. 
For example, the security management process standard requires 
implementation of a risk analysis, risk management, a sanction policy, 
and an information system activity review. The information access 
management standard requires consideration, and implementation where 
appropriate and reasonable, of access authorization and access 
establishment and modification policies and procedures. Other areas 
addressed are assigned security responsibility, workforce security, 
security awareness and training, security incident procedures, 
contingency planning, business associate contracts, and evaluation.
    h. Comment: One commenter stated that internal and external 
security requirements should be separated and dealt with independently.
    Response: The presentation of the standards within this final rule 
could have been structured in numerous ways, including by addressing 
separate internal and external security standards. We chose the current 
structure as we considered it a logical breakout for purposes of 
display within this final rule. Under our structure a covered entity 
may apply a given standard to internal activities and to external 
activities. Had we displayed separately the standards for internal 
security and the standards for external security, we would have needed 
to describe a number of the standards twice, as many apply to both 
internal and external security. However, a given entity may address the 
standards in whatever order it chooses, as long as the standards are 
met.
    i. Comment: Two commenters stated that the standards identified in 
Addendum 3 of the proposed rule may not all have matured to 
implementation readiness.
    Response: Addendum 3 of the proposed rule cross-referred individual 
requirements on the matrix to existing industry standards of varying 
levels of maturity. Addendum 3 was intended to show what we evaluated 
in searching for existing industry standards that could be adopted on a 
national level. No one standard was found to be comprehensive enough to 
be adopted, and none were proposed as the standards to be met under the 
Security Rule.
    j. Comment: One commenter suggested we include a revised preamble 
in the final publication. Another questioned how clarification of 
points in the preamble will be handled if the preamble is not part of 
the final regulation.
    Response: Preambles to proposed rules are not republished in the 
final rule. The preamble in this final rule contains summaries of the 
information presented in the preamble of the proposed rule, summaries 
of the comments received during the public comment period, and 
responses to questions and concerns raised in those comments and a 
summary of changes made. Additional clarification will be provided by 
HHS on an ongoing basis through written documents and postings on HHS's 
websites.
    k. Comment: One commenter asked that we clarify that no third party 
can require implementation of more security features than are required 
in the final rule, for example, a third party could not require 
encryption but may choose to accept it if the other party so desires.
    Response: The security standards establish a minimum level of 
security to be met by covered entities. It is not our intent to limit 
the level of security that may be agreed to between trading partners or 
others above this floor.
    l. Comment: One commenter asked how privacy legislation would 
affect these rules. The commenter inquired whether covered entities 
will have to reassess and revise actions already taken in the spirit of 
compliance with the security regulations.
    Response: We cannot predict if or how future legislation may affect 
the rules below. At present, the privacy standards at subpart E of 42 
CFR part 164 have been adopted, and this final rule is compatible with 
them.
    m. Comment: One commenter stated that a data classification policy, 
that is a method of assigning sensitivity ratings to specific pieces of 
data, should be part of the final regulations.
    Response: We did not adopt such a policy because this final rule 
requires a floor of protection of all electronic protected health 
information. A covered entity has the option to exceed this floor. The 
sensitivity of information, the risks to and vulnerabilities of 
electronic protected health information and the means that should be 
employed to protect it are business determinations and decisions to be 
made by each covered entity.
    n. Comment: One commenter stated that this proposed rule conflicts 
with previously stated rules that acceptable ``standards'' must have 
been developed by ANSI-recognized Standards Development Organizations 
(SDOs).
    Response: In general, HHS is required to adopt standards developed 
by ANSI-accredited SDOs when such standards exist. The currently 
existing security standards developed by ANSI-recognized SDOs are 
targeted to specific technologies and/or activities. No existing 
security standard, or group of standards, is technology-neutral, 
scaleable to the extent required by HIPAA, and broad enough to be 
adopted in this final rule. Therefore, this final rule adopts standards 
under section 1172(c)(2)(B) of the Act, which permits us to develop 
standards when no industry standards exist.
    o. Comment: One commenter stated that this regulation goes beyond 
the scope of the law, unjustifiably extending into business practices, 
employee policies, and facility security.
    Response: We do not believe that this regulation goes beyond the 
scope of the law. The law requires HHS to adopt standards for 
reasonable and appropriate security safeguards concerning such matters 
as compliance by the officers and employees of covered entities, 
protection against reasonably anticipated unauthorized uses and 
disclosures of health information, and so on. Such standards will 
inevitably address the areas the commenter pointed to.
    The intent of this regulation is to provide standards for the 
protection of electronic protected health information in accordance 
with the Act. In order to do this, covered entities are required to 
implement administrative, physical, and technical safeguards. Those 
entities must ensure that data are protected, to the extent feasible, 
from inappropriate access, modification, dissemination, and 
destruction. As noted above, however, this final rule has been modified 
to increase flexibility as to how this protection is accomplished.
    p. Comment: One commenter stated that all sections regarding 
confidentiality and privacy should be removed, since they do not belong 
in this regulation.
    Response: As the discussion in section III.A above of this final 
rule makes clear, the privacy and security standards are very closely 
related. Section 1173(d)(2) of the Act specifically mentions 
``confidentiality'' and authorizes uses and disclosures of information 
as part of what security safeguards must address. Thus, we cannot omit 
all references to confidentiality and privacy in discussions of the 
security standards.


[[Page 8346]]


 However, we have relocated material that relates to both security and 
privacy (including definitions) to the general section of part 164.
    q. Comment: One commenter asked that data retention be addressed 
more specifically, since this will become a significant issue over 
time. It is recommended that a national work group be convened to 
address this issue.
    Response: The commenter's concern is noted. While the documentation 
relating to Security Rule implementation must be retained for a period 
of 6 years (see Sec.  164.316(b)(2)), it is not within the scope of 
this final rule to address data retention time frames for 
administrative or clinical records.
    r. Comment: One commenter stated that requiring provider practices 
to develop policies, procedures, and training programs and to implement 
record keeping and documentation systems would be tremendously 
resource-intensive and increase the costs of health care.
    Response: We expect that many of the standards of this final rule 
are already being met in one form or another by covered entities. For 
example, as part of normal business operations, health care providers 
already take measures to protect the health information in their 
keeping. Health care providers already keep records, train their 
employees, and require employees to follow office policies and 
procedures. Similarly, health plans are already frequently required by 
State law to keep information confidential. While revisions to a 
practice's or plan's current activities may be necessary, the 
development of entirely new systems or procedures may not be necessary.
    s. Comment: One commenter stated that there is no system for which 
risk has been eliminated and expressed concern over phrases such as 
covered entities must ``assure that electronic health information 
pertaining to an individual remains secure.''
    Response: We agree with the commenter that there is no such thing 
as a totally secure system that carries no risks to security. 
Furthermore, we believe the Congress' intent in the use of the word 
``ensure'' in section 1173(d) of the Act was to set an exceptionally 
high goal for the security of electronic protected health information. 
However, we note that the Congress also recognized that some trade-offs 
would be necessary, and that ``ensuring'' protection did not mean 
providing protection, no matter how expensive. See section 
1173(d)(1)(A)(ii) of the Act. Therefore, when we state that a covered 
entity must ensure the safety of the information in its keeping, we 
intend that a covered entity take steps, to the best of its ability, to 
protect that information. This will involve establishing a balance 
between the information's identifiable risks and vulnerabilities, and 
the cost of various protective measures, and will also be dependent 
upon the size, complexity, and capabilities of the covered entity, as 
provided in Sec.  164.306(b).


E. Administrative Safeguards (Sec.  164.308)


    We proposed that measures taken to comply with the rule be 
appropriate to protect the health information in a covered entity's 
care. Most importantly, we proposed to require that both the measures 
taken and documentation of those measures be kept current, that is, 
reviewed and updated periodically to continue appropriately to protect 
the health information in the care of covered entities. We would have 
required the documentation to be made available to those individuals 
responsible for implementing the procedure.
    We proposed a number of administrative requirements and supporting 
implementation features, and required documentation for those 
administrative requirements and implementation features.
    In this final rule, we have placed these administrative standards 
in Sec.  164.308. We have reordered them, deleted much of the detail of 
the proposed requirements, as discussed below, and omitted two of the 
proposed sets of requirements (system configuration requirements and a 
requirement for a formal mechanism for processing records) as discussed 
in paragraph 10 of the discussion of Sec.  164.308 of section III.E. of 
this preamble. Otherwise, the basic elements of the administrative 
safeguards are adopted in this final rule as proposed.
1. Security Management Process (Sec.  164.308(a)(1)(i))
    We proposed the establishment of a formal security management 
process to involve the creation, administration, and oversight of 
policies to address the full range of security issues and to ensure the 
prevention, detection, containment, and correction of security 
violations. This process would include implementation features 
consisting of a risk analysis, risk management, and sanction and 
security policies.
    We also proposed, in a separate requirement under administrative 
procedures, an internal audit, which would be an in-house review of the 
records of system activity (for example, logins, file accesses, and 
security incidents) maintained by an entity.
    In this final rule, risk analysis, risk management, and sanction 
policy are adopted as required implementation specifications although 
some of the details are changed, and the proposed internal audit 
requirement has been renamed as ``information system activity review'' 
and incorporated here as an additional implementation specification.
    a. Comment: Three commenters asked that this requirement be 
deleted. Two commenters cited this requirement as a possible burden. 
Several commenters asked that the implementation features be made 
optional.
    Response: This standard and its component implementation 
specifications form the foundation upon which an entity's necessary 
security activities are built. See NIST SP 800-30, ``Risk Management 
Guide for Information Technology Systems,'' chapters 3 and 4, January 
2002. An entity must identify the risks to and vulnerabilities of the 
information in its care before it can take effective steps to eliminate 
or minimize those risks and vulnerabilities. Some form of sanction or 
punishment activity must be instituted for noncompliance. Indeed, we 
question how the statutory requirement for safeguards ``to ensure 
compliance * * * by a [covered entity's] officers and employees'' could 
be met without a requirement for a sanction policy. See section 
1176(d)(2)(C) of the Act. Accordingly, implementation of these 
specifications remains mandatory. However, it is important to note that 
covered entities have the flexibility to implement the standard in a 
manner consistent with numerous factors, including such things as, but 
not limited to, their size, degree of risk, and environment. We have 
deleted the implementation specification calling for an organizational 
security policy, as it duplicated requirements of the security 
management and training standard.
    We note that the implementation specification for a risk analysis 
at Sec.  164.308(a)(1)(ii)(A) does not specifically require that a 
covered entity perform a risk analysis often enough to ensure that its 
security measures are adequate to provide the level of security 
required by Sec.  164.306(a). In the proposed rule, an assurance of 
adequate security was framed as a requirement to keep security measures 
``current.'' We continue to believe that security measures must remain 
current, and have added regulatory language in Sec.  164.306(e) as a 
more precise way of communicating that security measures


[[Page 8347]]


in general that must be periodically reassessed and updated as needed.
    The risk analysis implementation specification contains other terms 
that merit explanation. Under Sec.  164.308(a)(1)(ii)(A), the risk 
analysis must look at risks to the covered entity's electronic 
protected health information. A thorough and accurate risk analysis 
would consider ``all relevant losses'' that would be expected if the 
security measures were not in place. ``Relevant losses'' would include 
losses caused by unauthorized uses and disclosures and loss of data 
integrity that would be expected to occur absent the security measures.
    b. Comment: Relative to the development of an entity's sanction 
policy, one commenter asked that we describe the sanction penalties for 
breach of security. Another suggested establishment of a standard to 
which one's conduct could be held and adoption of mitigating 
circumstances so that the fact that a person acted in good faith would 
be a factor that could be used to reduce or otherwise minimize any 
sanction imposed. Another commenter suggested sanction activities not 
be implemented before the full implementation and testing of all 
electronic transaction standards.
    Response: The sanction policy is a required implementation 
specification because--(1) the statute requires covered entities to 
have safeguards to ensure compliance by officers and employees; (2) a 
negative consequence to noncompliance enhances the likelihood of 
compliance; and (3) sanction policies are recognized as a usual and 
necessary component of an adequate security program. The type and 
severity of sanctions imposed, and for what causes, must be determined 
by each covered entity based upon its security policy and the relative 
severity of the violation.
    c. Comment: Commenters requested the definitions of ``risk 
analysis'' and ``breach.''
    Response: ``Risk analysis'' is defined and described in the 
specification of the security management process standard, and is 
discussed in the preamble discussion of Sec.  164.308(a)(1)(ii)(A) of 
this final rule. The term breach is no longer used and is, therefore, 
not defined.
    d. Comment: One commenter asked whether all health information is 
considered equally ``sensitive,'' the thought being that, in 
determining risk, an entity may consider the loss of a smaller amount 
of extraordinarily sensitive data to be more significant than the loss 
of a larger amount of routinely collected data. The commenter stated 
that common reasoning would suggest that the smaller amount of data 
would be considered more sensitive.
    Response: All electronic protected health information must be 
protected at least to the degree provided by these standards. If an 
entity desires to protect the information to a greater degree than the 
risk analysis would indicate, it is free to do so.
    e. Comment: One commenter asked that we add ``threat assessment'' 
to this requirement.
    Response: We have not done this because we view threat assessment 
as an inherent part of a risk analysis; adding it would be redundant.
    f. Comment: We proposed a requirement for internal audit, the in-
house review of the records of system activity (for example, logins, 
file accesses, and security incidents) maintained by an entity. Several 
commenters wanted this requirement deleted. One suggested the audit 
trail requirement should not be mandatory, while another stated that 
internal audits would be unnecessary if physical security requirements 
are implemented.
    A number of commenters asked that we clarify the nature and scope 
of what an internal audit covers and what the audit time frame should 
be. Several commenters offered further detail concerning what should 
and should not be required in an internal audit for security purposes. 
One commenter stated that ongoing intrusion detection should be 
included in this requirement. Another wanted us to specify the 
retention times for archived audit logs.
    Several commenters had difficulty with the term ``audit'' and 
suggested we change the title of the requirement to ``logging and 
violation monitoring.''
    A number of commenters stated this requirement could result in an 
undue burden and would be economically unfeasible.
    Response: Our intent for this requirement was to promote the 
periodic review of an entity's internal security controls, for example, 
logs, access reports, and incident tracking. The extent, frequency, and 
nature of the reviews would be determined by the covered entity's 
security environment. The term ``internal audit'' apparently, based on 
the comments received, has certain rigid formal connotations we did not 
intend. We agree that the implementation of formal internal audits 
could prove burdensome or even unfeasible, to some covered entities due 
to the cost and effort involved. However, we do not want to overlook 
the value of internal reviews. Based on our review of the comments and 
the text to which they refer, it is clear that this requirement should 
be renamed for clarity and that it should actually be an implementation 
specification of the security management process rather than an 
independent standard. We accordingly remove ``internal audit'' as a 
separate requirement and add ``information system activity review'' 
under the security management process standard as a mandatory 
implementation specification.
2. Assigned Security Responsibility (Sec.  164.308(a)(2))
    We proposed that the responsibility for security be assigned to a 
specific individual or organization to provide an organizational focus 
and importance to security, and that the assignment be documented. 
Responsibilities would include the management and supervision of (1) 
the use of security measures to protect data, and (2) the conduct of 
personnel in relation to the protection of data.
    In this final rule, we clarify that the final responsibility for a 
covered entity's security must be assigned to one official. The 
requirement for documentation is retained, but is made part of Sec.  
164.316 below. This policy is consistent with the analogous policy in 
the Privacy Rule, at 45 CFR 164.530(a), and the same considerations 
apply. See 65 FR 82744 through 87445. The same person could fill the 
role for both security and privacy.
    a. Comment: Commenters were concerned that delegation of assigned 
security responsibility, especially in large organizations, needs to be 
to more than a single individual. Commenters believe that a large 
health organization's security concerns would likely cross many 
departmental boundaries requiring group responsibility.
    Response: The assigned security responsibility standard adopted in 
this final rule specifies that final security responsibility must rest 
with one individual to ensure accountability within each covered 
entity. More than one individual may be given specific security 
responsibilities, especially within a large organization, but a single 
individual must be designated as having the overall final 
responsibility for the security of the entity's electronic protected 
health information. This decision also aligns this rule with the final 
Privacy Rule provisions concerning the Privacy Official.
    b. Comment: One commenter disagreed with placing assigned security 
responsibility as part of physical safeguards. The commenter suggested 
that assigned security responsibility should be included under the 
Administrative Procedures.


[[Page 8348]]


    Response: Upon review of the matrix and regulations text, we agree 
with the commenter, because this requirement involves an administrative 
decision at the highest levels of who should be responsible for 
ensuring security measures are implemented and maintained. Assigned 
security responsibility has been removed from ``Physical safeguards'' 
and is now located under ``Administrative safeguards'' at Sec.  
164.308.
3. Workforce Security (Sec.  164.308(a)(3)(i))
    We proposed implementation of a number of features for personnel 
security, including ensuring that maintenance personnel are supervised 
by a knowledgeable person, maintaining a record of access 
authorizations, ensuring that operating and maintenance personnel have 
proper access authorization, establishing personnel clearance 
procedures, establishing and maintaining personnel security policies 
and procedures, and ensuring that system users have proper training.
    In this final rule, to provide clarification and reduce 
duplication, we have combined the ``Assure supervision of maintenance 
personnel by authorized, knowledgeable person'' implementation feature 
and the ``Operating, and in some cases, maintenance personnel have 
proper access authorization'' feature into one addressable 
implementation specification titled ``Authorization and/or 
supervision.''
    In a related, but separate, requirement entitled ``Termination 
procedures,'' we proposed implementation features for the ending of an 
employee's employment or an internal or external user's access. These 
features would include things such as changing combination locks, 
removal from access lists, removal of user account(s), and the turning 
in of keys, tokens, or cards that allow access.
    In this final rule, ``Termination procedures'' has been made an 
addressable implementation specification under ``Workforce security.'' 
This is addressable because in certain circumstances, for example, a 
solo physician practice whose staff consists only of the physician's 
spouse, formal procedures may not be necessary.
    The proposed ``Personnel security policy/procedure'' and ``record 
of access authorizations'' implementation features have been removed 
from this final rule, as they have been determined to be redundant. 
Implementation of the balance of the ``Workforce security'' 
implementation specifications and the other standards contained within 
this final rule will result in assurance that all personnel with access 
to electronic protected health information have the required access 
authority as well as appropriate clearances.
    a. Comment: The majority of comments concerned the supervision of 
maintenance personnel by an authorized knowledgeable person. Commenters 
stated this would not be feasible in smaller settings. For example, the 
availability of technically knowledgeable persons to ensure this 
supervision would be an issue. We were asked to either reword this 
implementation feature or delete it.
    Response: We agree that a ``knowledgeable'' person may not be 
available to supervise maintenance personnel. We have accordingly 
modified this implementation specification so that, in this final rule, 
we are adopting an addressable implementation specification titled, 
``Authorization and/or supervision,'' requiring that workforce members, 
for example, operations and maintenance personnel, must either be 
supervised or have authorization when working with electronic protected 
health information or in locations where it resides (see Sec.  
164.308(a)(3)(ii)(A)). Entities can decide on the feasibility of 
meeting this specification based on their risk analysis.
    b. Comment: The second largest group of comments requested 
assurance that, with regard to the proposed ``Personnel clearance 
procedure'' implementation feature, having appropriate clearances does 
not mean performing background checks on everyone. We were asked to 
delete references to ``clearance'' and use the term ``authorization'' 
in its place.
    Response: We agree with the commenters concerning background 
checks. This feature was not intended to be interpreted as an absolute 
requirement for background checks. We retain the use of the term 
``clearance,'' however, because we believe that it more accurately 
conveys the screening process intended than does the term 
``authorization.'' We have attempted to clarify our intent in the 
language of Sec.  164.308(a)(3)(ii)(B), which now reads, ``Implement 
procedures to determine that the access of a workforce member to 
electronic protected health information is appropriate.'' The need for 
and extent of a screening process is normally based on an assessment of 
risk, cost, benefit, and feasibility as well as other protective 
measures in place. Effective personnel screening processes may be 
applied in a way to allow a range of implementation, from minimal 
procedures to more stringent procedures based on the risk analysis 
performed by the covered entity. So long as the standard is met and the 
underlying standard of Sec.  164.306(a) is met, covered entities have 
choices in how they meet these standards. To clarify the intent of this 
provision, we retitle the implementation specification ``Workforce 
clearance procedure.''
    c. Comment: One commenter asked that we expand the implementation 
features to include the identification of the restrictions that should 
be placed on members of the workforce and others.
    Response: We have not adopted this comment in the interest of 
maintaining flexibility as discussed in Sec.  164.306. Restrictions 
would be dependent upon job responsibilities, the amount and type of 
supervision required and other factors. We note that a covered entity 
should consider in this regard the applicable requirements of the 
Privacy Rule (see, for example, Sec.  164.514(d)(2) (relating to 
minimum necessary requirements), and Sec.  164.530(c) (relating to 
safeguards).
    Comment: One commenter believes that the proposed ``Personnel 
security'' requirement was reasonable, since an administrative 
determination of trustworthiness is needed before allowing access to 
sensitive information. Two commenters asked that we delete the 
requirement entirely. A number of commenters requested that we delete 
the implementation features. Another commenter stated that all the 
implementation features may not be applicable or even appropriate to a 
given entity and should be so qualified.
    Response: While we do not believe this requirement should be 
eliminated, we agree that all the implementation specifications may not 
be applicable or even appropriate to a given entity. For example, a 
personal clearance may not be reasonable or appropriate for a small 
provider whose only assistant is his or her spouse. The implementation 
specifications are not mandatory, but must be addressed. This final 
rule has been changed to reflect this approach (see Sec.  
164.308(a)(3)(ii)(B)).
    e. Comment: The majority of commenters on the ``Termination 
procedures'' requirement asked that it be made optional, stating that 
it may not be applicable or even appropriate in all circumstances and 
should be so qualified or posed as guidelines. A number of commenters 
stated that the requirement should be deleted. One commenter stated 
that much of the material covered under the ``Termination procedures'' 
requirement is already covered in ``Information access control.'' A 
number of commenters stated that this requirement


[[Page 8349]]


was too detailed and some of the requirements excessive.
    Response: Based upon the comments received, we agree that 
termination procedures should not be a separate standard; however, 
consideration of termination procedures remains relevant for any 
covered entity with employees, because of the risks associated with the 
potential for unauthorized acts by former employees, such as acts of 
retribution or use of proprietary information for personal gain. We 
further agree with the reasoning of the commenters who asked that these 
procedures be made optional; therefore, ``Termination procedures'' is 
now reflected in this final rule as an addressable implementation 
specification. We also removed reference to all specific termination 
activities, for example, changing locks, because, although the 
activities may be considered appropriate for some covered entities, 
they may not be reasonable for others.
    f. Comment: One commenter asked whether human resource employee 
termination policies and procedures must be documented to show the 
types of security breaches that would result in termination.
    Response: Policies and procedures implemented to adhere to this 
standard must be documented (see Sec.  164.316 below). The purpose of 
termination procedure documentation under this implementation 
specification is not to detail when or under which circumstances an 
employee should be terminated. This information would more 
appropriately be part of the entity's sanction policy. The purpose of 
termination procedure documentation is to ensure that termination 
procedures include security-unique actions to be followed, for example, 
revoking passwords and retrieving keys when a termination occurs.
4. Information Access Management (Sec.  164.308(a)(4))
    We proposed an ``information access control'' requirement for 
establishment and maintenance of formal, documented policies and 
procedures defining levels of access for all personnel authorized to 
access health information, and how access is granted and modified. In 
Sec.  164.308(a)(4)(ii)(B) and (C) below, the proposed implementation 
features are made addressable specifications. We have added in Sec.  
164.308(a)(4)(ii)(A), a required implementation specification to 
isolate health care clearinghouse functions to address the provisions 
of section 1173(d)(1)(B) of the Act which related to this area.
    a. Comment: One commenter asked that the requirement be deleted, 
expressing the opinion that this requirement goes beyond ``reasonable 
boundaries'' into regulating common business practices. In contrast, 
another asked that we expand this requirement to identify participating 
parties and access privileges relative to specific data elements.
    Response: We disagree that this requirement improperly imposes upon 
business functions. Restricting access to those persons and entities 
with a need for access is a basic tenet of security. By this mechanism, 
the risk of inappropriate disclosure, alteration, or destruction of 
information is minimized. We cannot, however, specifically identify 
participating parties and access privileges relative to data elements 
within this regulation. These will vary depending upon the entity, the 
needs within the user community, the system in which the data resides, 
and the specific data being accessed. This standard is consistent with 
Sec.  164.514(d) in the Privacy Rule (minimum necessary requirements 
for use and disclosure of protected health information), and is, 
therefore, being retained.
    b. Comment: Several commenters asked that we not mandate the 
implementation features, but leave them as optional, a suggested means 
of compliance. The commenters noted that this might make the rules more 
scalable and flexible, since this approach would allow providers to 
implement safeguards that best addressed their needs. Along this line, 
one commenter expressed the belief that each organization should 
implement features deemed necessary based on its own risk assessment.
    Response: While the information access management standard in this 
final rule must be met, we agree that the implementation specifications 
at Sec.  164.308(a)(4)(ii)(B) and (C) should not be mandated but posed 
as a suggested means of compliance, which must be addressed. These 
specifications may not be applicable to all entities based on their 
size and degree of automation. A fully automated covered entity 
spanning multiple locations and involving hundreds of employees may 
determine it has a need to adopt a formal policy for access 
authorization, while a small provider may decide that a desktop 
standard operating procedure will meet the specifications. The final 
rule has been revised accordingly.
    c. Comment: Clarification was requested concerning the meaning of 
''formal.''
    Response: The word ``formal'' has caused considerable concern among 
commenters, as it was thought ``formal'' carried the connotation of a 
rigidly defined structure similar to what might be found in the 
Department of Defense instructions. As used in the proposed rule, this 
word was not intended to convey such a strict structure. Rather, it was 
meant to convey that documentation should be an official organizational 
statement as opposed to word-of-mouth or cryptic notes scratched on a 
notepad. While documentation is still required (see Sec.  164.316), to 
alleviate confusion, the word ``formal'' has been deleted.
    d. Comment: One commenter asked that we clarify that this 
requirement relates to both the establishment of policies for the 
access control function and to access control (the implementation of 
those policies).
    Response: ``Information access management'' does address both the 
establishment of access control policies and their implementation. We 
use the term ``implement'' to clarify that the procedures must be in 
use, and we believe that the requirement to implement policies and 
procedures requires, as an antecedent condition, the establishment or 
adaptation of those policies and procedures.
5. Security Awareness and Training (Sec.  164.308(a)(5)(i))
    We proposed, under the requirement ``Training,'' that security 
training be required for all staff, including management. Training 
would include awareness training for all personnel, periodic security 
reminders, user education concerning virus protection, user education 
in the importance of monitoring login success/failure, and how to 
report discrepancies, and user education in password management.
    In this final rule, we adopt this proposed requirement in modified 
form. For the standard ``Security awareness and training,'' in Sec.  
164.308(a)(5), we require training of the workforce as reasonable and 
appropriate to carry out their functions in the facility. All proposed 
training features have been combined as implementation specifications 
under this standard. Specific implementation specifications relative to 
content are addressable. The ``Virus protection'' implementation 
feature has been renamed ``protection from malicious software,'' 
because we did not intend by the nomenclature to exclude coverage of 
malicious acts that might not come within the prior term, such as 
worms.
    a. Comment: One commenter believes that security awareness training 
for all


[[Page 8350]]


system users would be too difficult to do in a large organization.
    Response: We disagree with the commenter. Security awareness 
training is a critical activity, regardless of an organization's size. 
This feature would typically become part of an entity's overall 
training program (which would include privacy and other information 
technology items as well). For example, the Government Information 
Systems Reform ACT (GISRA) of 2000 requires security awareness training 
as part of Federal agencies' information security programs, including 
Federal covered entities, such as the Medicare program. In addition, 
National Institute of Standards and Technology (NIST) SP 800-16, 
Information Technology Security Training Requirements, A role and 
performance base model, April 1998, provides an excellent source of 
information and guidance on this subject and is targeted at industry as 
well as government activities. We also note that covered entities must 
have discretion in how they implement the requirement, so they can 
incorporate this training in other existing activities. One approach 
would be to require this training as part of employee orientation.
    b. Comment: A number of commenters asked that this requirement be 
made optional or used as a guideline only. Several commenters stated 
that this requirement is too specific and is burdensome. Several asked 
that the implementation features be removed.
    Several others stated that this requirement is not appropriate for 
agents or contractors. One commenter asked how to apply this 
requirement to outsiders having access to data. Another asked if this 
requirement included all subcontractor staff. Others stated that 
contracts, signed by entities such as consultants, that address 
training should be sufficient.
    Response: Security training remains a requirement because of its 
criticality; however, we have revised the implementation specifications 
to indicate that the amount and type of training needed will be 
dependent upon an entity's configuration and security risks. Business 
associates must be made aware of security policies and procedures, 
whether through contract language or other means. Covered entities are 
not required to provide training to business associates or anyone else 
that is not a member of their workforce.
    c. Comment: Several commenters questioned why security awareness 
training appeared in two places, under ``Physical safeguards'' as well 
as ``Administrative safeguards.'' Others questioned the appropriateness 
of security awareness training under ``Physical safeguards.''
    Response: We reviewed the definitions of the proposed ``Awareness 
training for all personnel'' (``Administrative safeguards'') 
implementation feature and the proposed ``Security awareness training'' 
(``Physical safeguards'') requirement. We agree that, to avoid 
confusion and eliminate redundancy, security awareness and training 
should appear in only one place. We believe the appropriate location 
for it is under ``Administrative safeguards,'' as such training is 
essentially an administrative function.
    d. Comment: Several commenters objected to the blanket requirement 
for security awareness training of individuals who may be on site for a 
limited time period (for example, a single day).
    Response: Each individual who has access to electronic protected 
health information must be aware of the appropriate security measures 
to reduce the risk of improper access, uses, and disclosures. This 
requirement does not mean lengthy training is appropriate in every 
instance; there are alternative methods to inform individuals of 
security responsibilities (for example, provisions of pamphlets or 
copies of security policies, and procedures).
    e. Comment: One commenter asked that ``training'' be changed to 
``orientation.''
    Response: We believe the term ``training,'' as presented within 
this rule is the more appropriate term. The rule does not contemplate a 
one-time type of activity as connoted by ``orientation,'' but rather an 
on-going, evolving process as an entity's security needs and procedures 
change.
    f. Comment: Several commenters asked how often training should be 
conducted and asked for a definition of ``periodic,'' as it appears in 
the proposed implementation feature ``Periodic security reminders.'' 
One asked if the training should be tailored to job need.
    Response: Amount and timing of training should be determined by 
each covered entity; training should be an on-going, evolving process 
in response to environmental and operational changes affecting the 
security of electronic protected health information. While initial 
training must be carried out by the compliance date, we provide 
flexibility for covered entities to construct training programs. 
Training can be tailored to job need if the covered entity so desires.
6. Security Incident Procedures (Sec.  164.308(a)(6))
    We proposed a requirement for implementation of accurate and 
current security incident procedures: formal, documented report and 
response procedures so that security violations would be reported and 
handled promptly. We adopt this standard in the final rule, along with 
an implementation specification for response and reporting, since 
documenting and reporting incidents, as well as responding to incidents 
are an integral part of a security program.
    a. Comment: Several commenters asked that we further define the 
scope of a breach of security. Along this same line, another commenter 
stated that the proposed security incident procedures were too vague as 
stated. We were asked to specify what a security incident would be, 
what the internal chain for reporting procedures would be, and what 
should be included in the documentation (for example, hardware/
software, personnel responses).
    Response: We define a security incident in Sec.  164.304. Whether a 
specific action would be considered a security incident, the specific 
process of documenting incidents, what information should be contained 
in the documentation, and what the appropriate response should be will 
be dependent upon an entity's environment and the information involved. 
An entity should be able to rely upon the information gathered in 
complying with the other security standards, for example, its risk 
assessment and risk management procedures and the privacy standards, to 
determine what constitutes a security incident in the context of its 
business operations.
    b. Comment: One commenter asked what types of incidents must be 
reported to outside entities. Another commented that we clarify that 
incident reporting is internal.
    Response: Internal reporting is an inherent part of security 
incident procedures. This regulation does not specifically require any 
incident reporting to outside entities. External incident reporting is 
dependent upon business and legal considerations.
    c. Comment: One commenter stated that network activity should be 
included here.
    Response: We see no reason to exclude network activity under this 
requirement. Improper network activity should be treated as a security 
incident, because, by definition, it represents an improper instance of 
access to or use of information.


[[Page 8351]]


    d. Comment: One commenter stated that this requirement should 
address suspected misuse also.
    Response: We agree that security incidents include misuse of data; 
therefore, this requirement is addressed.
    e. Comment: Several commenters asked that this requirement be 
deleted. One commenter asked that we delete the implementation 
features.
    Response: As indicated above, we have adopted the proposed standard 
and combined the implementation specifications.
7. Contingency Plan (Sec.  164.308(a)(7)(i))
    We proposed that a contingency plan must be in effect for 
responding to system emergencies. The plan would include an 
applications and data criticality analysis, a data backup plan, a 
disaster recovery plan, an emergency mode operation plan, and testing 
and revision procedures.
    In this final rule, we make the implementation specifications for 
testing and revision procedures and an applications and data 
criticality analysis addressable, but otherwise require that the 
contingency features proposed be met.
    a. Comment: Several
