Which agency oversees the implementation of the National Industrial Security Program (NISP)?

The Defense Security Service (DSS) is the agency responsible for overseeing the implementation of the National Industrial Security Program (NISP). This program is critical for ensuring that U.S. government and contractor facilities protect classified information from unauthorized disclosure.

DSS operates under the Department of Defense and has a primary role in managing the security clearance process for personnel working in companies that contract with the government. This agency ensures that these organizations comply with security regulations and provides training and support to help them safeguard sensitive materials. By overseeing the NISP, DSS plays a pivotal role in maintaining national security by managing industrial security across various sectors.

The other agencies mentioned do not have the same specific role in overseeing the NISP as DSS does. For instance, the FBI focuses on federal law enforcement and counterterrorism, while the NSA primarily deals with signal intelligence and cybersecurity. The Department of Homeland Security focuses on protecting the nation from threats, but it does not have the specific mandate to oversee the industrial security aspects of classified information as DSS does.
