Which of the following is NOT a component of OPSEC?

Operational Security (OPSEC) involves a series of measures designed to protect sensitive information from being accessed by adversaries. This process consists of several key components including identifying critical information, assessing threats, and analyzing vulnerabilities.

Identifying critical information is essential as it helps determine what information needs to be protected. Assessing threats involves understanding what potential adversaries exist and what they might do to exploit vulnerabilities. Analyzing vulnerabilities focuses on recognizing weaknesses in the current security posture that could be targeted by those threats.

While implementing training is an important aspect of maintaining overall security and ensuring personnel are aware of protective measures, it is not classified as a core component of OPSEC itself. Instead, training can be viewed as a supportive activity that enhances the effectiveness of OPSEC practices rather than a fundamental component in the structure of OPSEC processes. Thus, it stands out as the option that does not directly align with the primary functions of OPSEC.
