Communications Security (COMSEC)

COMSEC is defined as the measures taken to deny unauthorized persons information derived from telecommunications of the U.S. Government concerning national security, and to ensure the authenticity of such telecommunications. The Department of Labor (DOL) has the legal obligation to provide the necessary security surrounding the use of communication devices. The Emergency Management Center (EMC) manages DOL's COMSEC program. DOL's COMSEC policies and procedures include those involving the use of cryptographic security measures, emissions security, transmission security, and physical security of COMSEC aids and hardware used to encrypt and protect sensitive or classified communications.
