FAS FF-L-2740B

The purpose of this document is to describe the U.S Government's
requirements and expectations for a combination lock designed and
manufactured specifically to protect unattended national security
information (NSI). Combination locks approved under this
specification will be used on new and existing General Services
Administration (GSA) approved security containers, vault doors and
pedestrian door and pedestrian door deadbolts. These combination
locks should incorporate modem electronic security techniques. The
collective power of the Internet has created an increase in the
number and sophistication of computer and electronic system hacking
techniques. The new generation of electromechanical combination
locks uses microprocessors with software codes that can be
manipulated during manufacture and transportation. Security
features designed to ensure the code has not been altered during
manufacture and transportation are required. The vulnerabilities of
the new coding techniques mandates the development of new security
requirements on the manufactures to ensure the electronic
components and software are adequately protected and are accessed
only by personnel subject to U.SS.law.
