Communications security is the discipline of preventing unauthorized interceptors from accessing telecommunications in an intelligible form, while still delivering content to the intended recipients. In the United States Department of Defense culture, it is often referred to by the abbreviation COMSEC. The field includes cryptosecurity, transmission security, emission security, traffic-flow security. and physical security of COMSEC equipment.
COMSEC is used to protect both classified and unclassified traffic on military communications networks, including voice, video, and data. It is used for both analog and digital applications, and both wired and wireless links.
Secure voice over internet protocol (SVOIP) has become the de facto standard for securing voice communication, replacing the need for STU-X and STE equipment in much of the U.S. Department of Defense. USCENTCOM moved entirely to SVOIP in 2008.
