What term describes control information and observable actions about mission capabilities, limitations, and intentions to prevent exploitation by an adversary?

• A. COMSEC
• B. OPSEC
• C. INFOSEC
• D. C2SEC

Answer: (B)

Operational security focuses on protecting critical information by controlling what an adversary can observe or infer about mission capabilities, limitations, and intentions. By reducing indicators and limiting what is exposed through actions, timing, or patterns, you prevent enemies from exploiting those details. The description in the question matches OPSEC because it emphasizes managing control information and observable actions to prevent exploitation. In contrast, COMSEC deals with securing communications and cryptographic material, INFOSEC covers information security across systems and data, and C2SEC isn’t a standard term in this context. So, the best choice is operational security.
