Which agency clears industrial facilities, accredits information systems, facilitates the personnel security clearance process, delivers security education, training, and certification, and provides information technology services to support security missions?

• A. Defense Counterintelligence and Security Agency (DCSA)
• B. Defense Central Index of Investigations (DCII)
• C. Under Secretary of Defense for Intelligence and Security
• D. Industrial Security Representative (IS Rep)

Answer: (A)

This item is about which DoD entity unifies and executes the security functions for contractors handling classified information. The Defense Counterintelligence and Security Agency is the organization responsible for implementing the National Industrial Security Program, bringing together the core industrial-security duties in one place. It clears industrial facilities by issuing Facility Clearances, accredits the information systems that store or process classified data to ensure proper protection, and oversees the personnel security clearance process through coordination of background investigations and adjudication support. It also delivers security education, training, and certification to personnel and provides information technology services to support security missions, such as secure IT infrastructure and related services.

The other options don’t fit this comprehensive role. The central index of investigations is a data repository, not an agency. The Under Secretary of Defense for Intelligence and Security is a policy-level office, not the operational agency. An Industrial Security Representative is a field role, not the organization that administers the program nationwide.
