What does the term "COMSEC" refer to?

The term "COMSEC" stands for Communications Security, which encompasses the measures and procedures used to protect sensitive but unclassified communications from interception and exploitation. It involves various techniques such as encryption, transmission security, emission security, and physical security to safeguard communications and ensure that information is only accessible to authorized users.

Understanding COMSEC is essential, particularly in military and tactical contexts, as it safeguards operations and maintains the integrity of communications channels. This ensures that strategic and tactical information remains confidential and that communication systems function effectively without interference from adversaries.
