MEMORANDUM FOR DEFENSE PRIVACY, CIVIL LIBERTIES AND TRANSPARENCY

DIVISION

THROUGH: RECORDS, PRIVACY AND DECLASSIFICATION DIVISION

SUBJECT: Justification for the Use of the Social Security Number (SSN) in NBIS Defense Information System for Security Version 2 (DISS) DITPR ID #1640

1. System / Form

This memorandum is written to satisfy the requirement established in Department of Defense Instruction (DoDI) 1000.30, “Reduction of Social Security Number (SSN) Use Within DoD,” that requires justification of the collection and use of the SSN in the Defense Information System for Security (DISS).

DISS is a DoD enterprise automated system for personnel security, providing a common, comprehensive medium to record, document, and identify personnel security actions within the Department including submitting adverse information, verification of clearance status (to include grants of interim clearances), requesting investigations, and supporting Continuous Evaluation activities. The DISS is the replacement system for the Joint Personnel Adjudication System (JPAS).

2. Documentation

The information collected is covered by the Personnel Vetting Records System, DUSDI 02-DoD. (October 17, 2018; 83 FR 52420). DISS is secured to protect Personally Identifiable Information (PII) in accordance with the Privacy Act of 1974 and DoD 5400.11-R, “Department of Defense Privacy Program.”

3. Authorized Uses

In accordance with DoDI 1000.30, Enclosure 2, paragraph 2.c.(2), use of the SSN within DISS falls under 03 acceptable use, ‘Security Clearance Investigation or Verification’. The SSN is the single identifier that links all aspects of a security clearance investigation together. This use case is also linked to other Federal agencies that continue to use the SSN as a primary identifier.

Plan of Action for the migration from/elimination of SSN is not applicable to DISS
