Locks used to secure classified information must comply with which specifications?

The specification FF-L-2740 is critical for ensuring that locks used to secure classified information meet specific security standards set forth by the federal government. This specification defines the performance requirements for locks used in facilities that house classified information. It covers aspects such as resistance to forced entry and manipulation, ensuring that such locks provide sufficient security to protect sensitive materials.

This standard is particularly relevant for the Physical Security realm because it provides guidelines that must be adhered to by manufacturers and users when implementing locking mechanisms within secure facilities. Locks complying with FF-L-2740 would be tested and certified for effectiveness in preventing unauthorized access, which is crucial for maintaining national security.

In contrast, while UL 437 is related to the testing of locks for resistance to surreptitious entry, it is not specific to classified information nor does it provide the comprehensive performance metrics required for safeguarding classified material as covered by FF-L-2740. FIPS 201 pertains to personal identity verification for federal employees and contractors, and ANSI/BHMA A156.5 is a standard for testing characteristics of locks but is not exclusively about the security of classified information. Thus, FF-L-2740 stands out as the appropriate specification for this purpose.
