Which is NOT one of the five Executive Branch Agencies designated as a Cognizant Security Agency (CSA)?

The designation of Cognizant Security Agencies (CSAs) is critical within the realm of national security to ensure that classified information is adequately protected across various sectors. The agencies identified as CSAs play a central role in managing and overseeing security protocols pertaining to national defense and classified materials.

The Department of Justice (DOJ) is not one of the five Executive Branch Agencies designated as a CSA. The focus of the DOJ is primarily on federal law enforcement and legal proceedings, rather than the administration of classified security protocols that the CSAs are responsible for.

In contrast, the Department of Defense (DoD), Department of Energy (DOE), and Department of State (DOS) are all integral agencies that manage and execute policies related to security in areas such as nuclear energy, military operations, and foreign relations, respectively. These agencies are directly involved in safeguarding sensitive information that relates to national security, thereby qualifying them as CSAs.

Understanding the distinction between these agencies helps clarify the responsibilities each has in relation to security management and classified information, which is crucial for anyone involved in or studying the Facility Security Officer role in the National Industrial Security Program.
