[Code of Federal Regulations] [Title 14, Volume 5] [Revised as of January 1, 2007] From the U.S. Government Printing Office via GPO Access [CITE: 14CFR1203.403] [Page 17-18] TITLE 14--AERONAUTICS AND SPACE CHAPTER V--NATIONAL AERONAUTICS AND SPACE ADMINISTRATION PART 1203_INFORMATION SECURITY PROGRAM--Table of Contents Subpart D_Guides for Original Classification Sec. 1203.403 State-of-the-art and intelligence. A logical approach to classification requires consideration of the extent to which the same or similar information available from intelligence sources is known or is available to others. It is also important to consider whether it is known publicly, either domestically or internationally, that the United States has the information or even is interested in the subject matter. The known state-of-the-art in other nations [[Page 18]] is an additional substantive factor requiring consideration.
