Which DoD system is utilized for verifying a facility clearance?

The Industrial Security Facilities Database (ISFD) is the correct choice because it serves as the primary system for tracking and verifying facility clearances within the context of national security and defense. ISFD stores essential information about facilities that have been granted security clearances to handle classified information, ensuring that data regarding these clearances is readily accessible to authorized individuals and organizations. This facilitates compliance with Department of Defense (DoD) regulations and helps maintain the integrity of classified operations.

When assessing other options, while the Defense Security Service (DSS) is responsible for overseeing and managing the industrial security program, it does not function as a database specifically for verifying facility clearances. The National Industrial Security Program (NISP) is a set of policies and guidelines under which the ISFD operates; however, it is not a verification system itself. Similarly, Cognizant Security Agencies (CSAs) are government entities that provide oversight for security practices but do not directly involve database functions for clearance verification like ISFD. Thus, the ISFD is specifically designed for the purpose of verifying and managing facility clearances effectively.
