Which of the following agencies is NOT part of the National Industrial Security Program (NISP) administration?

The Department of Justice is not part of the National Industrial Security Program (NISP) administration. The NISP is primarily managed by the Department of Defense and other Cognizant Security Agencies that play a direct role in overseeing industrial security for classified information.

The Secretary of Defense has significant authority over the NISP and sets the policies and procedures that govern how classified information is handled within the industrial base. Cognizant Security Agencies are those specific government entities that provide oversight and guidance to contractors concerning their security responsibilities. The National Security Council is involved in overarching national security policy but does not directly administer the NISP.

In contrast, the Department of Justice, while an important agency within the federal government, does not have a direct role in the administration of the NISP. Therefore, it cannot be considered part of the entities responsible for managing industrial security policies at the level outlined by the NISP. This distinction clarifies why the Department of Justice is the correct answer in this context.
