In OPSEC, which step involves identifying critical information?

• A. Identify critical information
• B. Assess Risk
• C. Analyze vulnerabilities
• D. Apply countermeasures

Answer: (A)

Identifying what information is critical to protect is the first step in OPSEC. By defining exactly which data, plans, or indicators would cause harm if exposed—such as mission details, timing, locations, or capabilities—you establish what needs protection. Once you know what’s critical, you can properly assess risk, analyze vulnerabilities, and apply countermeasures. Risk assessment uses the defined critical information to judge how likely threats are and the potential impact; vulnerability analysis finds weaknesses that could expose that information; countermeasures are then chosen to reduce the risk. Without identifying the critical information first, there’s no clear target for protection, which is why this step is the correct starting point.
