Final answer:
The primary database used to verify personnel access to SCIFs outside of DoD is the Joint Personnel Adjudication System (JPAS). It is an integrated, web-based system that provides comprehensive personnel security information and facilitates the adjudication process for security clearances.
Step-by-step explanation:
The primary database used to verify personnel access to SCIFs (Sensitive Compartmented Information Facilities) outside of the Department of Defense (DoD) is the Joint Personnel Adjudication System (JPAS). JPAS is an integrated, web-based system that provides comprehensive personnel security information and facilitates the adjudication process for security clearances. It is primarily used to determine an individual's eligibility for access to classified information and secure facilities.
JPAS is a vital tool for managing security clearances and conducting personnel security investigations. It allows authorized users to input, update, and retrieve security clearance information, including background investigation data, eligibility determinations, and access control information. The database serves as a central repository for security-related information and is accessible to DoD components, government agencies, and cleared contractors. JPAS employs various security measures to ensure the protection and integrity of the stored data, including encryption, access controls, and auditing mechanisms. It plays a crucial role in maintaining the security of SCIFs and controlling access to classified information.
