What does COMSEC stand for?

COMSEC stands for Communications Security. This term encompasses the measures and controls taken to protect and secure the integrity and confidentiality of communications. It includes various aspects such as encryption, secure communication channels, and procedures that ensure that only authorized personnel have access to sensitive communications. Effective COMSEC is vital for safeguarding national security interests and maintaining the confidentiality of classified information during transmission.

The other terms listed do not accurately reflect the established definition of COMSEC within the context of security measures related to communications. While confidentiality of materials, controlled material security, and complete material security could be relevant in different security contexts, they do not specifically address the comprehensive framework that COMSEC represents regarding communications technology and methods.
