Which executive branch agency is NOT a designated Cognizant Security Agency?

The Department of Justice (DOJ) is not a designated Cognizant Security Agency (CSA) within the National Industrial Security Program (NISP). The role of a Cognizant Security Agency is to oversee and manage the security aspects for cleared contractors and their facilities concerning classified information.

In the context of the NISP, the Department of Defense (DoD), Department of Homeland Security (DHS), and Department of Energy (DOE) are all designated CSAs. These agencies have specific responsibilities and authority under the NISP to provide guidance, oversight, and support relating to the protection of national security information. The DOJ, while it plays a critical role in law enforcement and legal matters surrounding national security, does not have direct responsibilities as a CSA for the purposes of the NISP. This distinction is essential for understanding the framework within which facility security officers operate, focusing on protecting classified information through directed oversight by designated agencies.
