COMSEC stands for which phrase?

• A. Computational Security
• B. Commercial Security
• C. Communication Security
• D. Cryptographic Security

Answer: (C)

COMSEC is concerned with protecting information as it travels across communications channels. It focuses on securing the channel itself—who is allowed to send and receive, how messages are protected in transit, and how cryptographic keys and related material are managed—so that transmissions stay confidential and untampered with. That emphasis on safeguarding communications, rather than on the computational difficulty of breaking things or on business-related protections, makes the standard phrase Communication Security the correct one. The other terms don’t fit because Computational Security refers to security built on computational assumptions, Commercial Security relates to protecting business interests, and Cryptographic Security centers on the strength of cryptographic techniques themselves, not the overall protection of the communications channel.
