Communications security

Communications security is the discipline of preventing unauthorized interceptors from accessing telecommunications[1] in an intelligible form, while still delivering content to the intended recipients.

COMSEC is used to protect both classified and unclassified traffic on military communications networks, including voice, video, and data.

[2] Types of COMSEC equipment: The Electronic Key Management System (EKMS) is a United States Department of Defense (DoD) key management, COMSEC material distribution, and logistics support system.

It eliminates paper keying material, hardcopy Signal operating instructions (SOI) and saves the time and resources required for courier distribution.

[4] This system is currently being fielded by Major Commands and variants will be required for non-DoD Agencies with a COMSEC Mission.
