The Defense Counterintelligence and Security Agency (DCSA) will begin to transition Industry hierarchy data from the Defense Information System for Security (DISS) to the National Background Investigation Services (NBIS) system on April 1, 2022. As part of this data migration, DCSA will move information from the National Industrial Security System (NISS)—the authoritative source for facility clearances, and DISS—the personnel security system of record and source of hierarchy used to manage personnel security programs. To prepare the NBIS data transition, DCSA recommends Industry partners who hold facility clearances to review DISS Security Management Offices (SMO), and determine if SMOs need consolidation into one SMO per CAGE code, to align with the cleared facility in NISS by March 31, 2022.
