Which term refers to the process of controlling information and observable actions about mission capabilities, limitations, and intentions to prevent exploitation by an adversary?

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

Answer: (A)

OPSEC is the process of identifying critical information and taking measures to hide or reduce its exposure to potential adversaries by controlling information and observable actions about mission capabilities, limitations, and intentions. The aim is to prevent exploitation by ensuring adversaries cannot deduce what you can do, what you can’t do, or what you plan to do. It involves analyzing threats, identifying vulnerabilities, and applying countermeasures such as concealing activities, following standard procedures, and managing how information is handled and shared. Other terms refer to different security realms: COMSEC protects the content and integrity of communications, INFOSEC is the broader field of information security, and CYBERSEC isn’t the standard term used for this specific practice.
