'''[[Communication protocol|Communications]] security''' is the discipline of preventing unauthorized interceptors from accessing [[telecommunications]]<ref name=":0" /> in an intelligible form, while still delivering content to the intended recipients.

In the [[North Atlantic Treaty Organization]] culture, including United States Department of Defense culture, it is often referred to by the abbreviation '''COMSEC'''.  The field includes cryptographic security, [[Glossary of cryptographic keys|transmission security]], emissions security and [[physical security]] of COMSEC equipment and associated keying material.

COMSEC is used to protect both [[Classified information|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.

Voice over secure internet protocol [[VOSIP]] has become the de facto standard for securing voice communication, replacing the need for [[Secure Terminal Equipment]] (STE) in much of NATO, including the U.S.A. [[USCENTCOM]] moved entirely to VOSIP in 2008.<ref>USCENTCOM PL 117-02-1.</ref>
