AOA of the airport in accordance with Sec. 1542.207.
    (2) Provide for detection of, and response to, each unauthorized 
presence or movement in, or attempted entry to, the AOA by an individual 
whose access is not authorized in accordance with its security program.
    (3) Provide security information as described in Sec. 1542.213(c)
