Which of the following is the first step in the OPSEC process?

The first step in the Operational Security (OPSEC) process is the identification of critical information. This step involves determining what information, if disclosed, could be detrimental to the mission or objectives of an organization. It sets the foundation for the entire OPSEC process because you cannot effectively protect what you do not identify as critical.

Identifying which pieces of information are vital allows security personnel to prioritize their efforts and develop strategies tailored to protecting those specific items. Once critical information is recognized, the subsequent steps—such as assessing risks, analyzing vulnerabilities, and applying countermeasures—can be effectively undertaken to safeguard that information. Ultimately, this process ensures a proactive rather than reactive approach to security.
