What does COMSEC stand for in military communications?

COMSEC stands for Communications Security, which encompasses measures taken to secure communications from interception and exploitation by adversaries. This includes the use of encryption, key management, and physical security of communication equipment. The integrity and confidentiality of military communications are critical for operational success, which is why COMSEC is a foundational element in military operations. Understanding COMSEC allows personnel to better protect sensitive information and maintain the reliability of communication channels. In contrast, the other options reference concepts that do not directly pertain to the measures and protocols associated with securing military communications.
