Which agency acts as the policy-making body for the National Industrial Security Program?

The Department of Defense (DoD) is the correct choice as it is the primary agency responsible for implementing and overseeing the National Industrial Security Program (NISP). The DoD establishes policies, procedures, and standards for how sensitive information is handled within the industrial base. As part of its role, the DoD works to ensure that classified information is properly protected when it is accessed or processed by contractors and other entities involved in national security.

The other agencies mentioned have different functions in relation to security and information oversight. The National Security Council (NSC) plays a broad advisory role concerning national security and foreign policy but does not directly oversee the NISP. The Defense Information Systems Agency (DISA) focuses on providing IT and communications support within the DoD, which is distinct from the specific policy-making aspect of the NISP. Similarly, the Information Security Oversight Office (ISOO) plays a role in overseeing the implementation of national security classification but does not serve as the primary policy-making body for the NISP itself.
