COMPLIANCE

December 17, 2019
MEMORANDUM FOR THE DEFENSE COUNTERINTELLIGENCE AND SECURITY
AGENCY
SUBJECT: Justification for the Use of Social Security Numbers in the National Industrial
Security System (NISS) - DITPR #14954 - Accepted
Thank you for completing a review of Social Security Number (SSN) use within this
system. The Defense Privacy, Civil Liberties and Transparency Division (DPCLTD) has
reviewed this request and has accepted your justification to use the SSN for the purpose of (3)
Security Clearance Investigation or Verification, to verify contractors’ eligibility for and ability
to maintain facility security clearances. Also, Acceptable Use (11) Legacy System Interface,
was accepted. NISS interfaces with the Defense Information System for Security (DISS) to
create security violation incident reports. This system must be reviewed on a continuous basis
and a new justification must be provided if any change to the system is submitted.
Acceptable Use (8) Computer Matching, was not accepted. This Acceptable Use applies to
systems/forms interfacing with non-Department of Defense federal systems. No description of
interfaces with other federal agencies (other than access to NISS) is addressed in the justification.
While this system has been identified as requiring the collection, maintenance and use of
the SSN, you must ensure this data is afforded the highest protections practicable through use of
appropriate administrative, technical and physical safeguards. Also, please maintain a copy of
your justification and this memo in your records.
SSN Justifications must be renewed three (3) years after the date of this memorandum if
the associated system has not been updated.
If you have any questions, please contact Ms. Cindy Stanley at (703) 571-0090 or email, cynthia.b.stanley2.civ@mail.mil.
