Consistent with Executive Order 13869, "Transferring Responsibility for Background Investigations to the Department of Defense," the Acting Secretary of Defense has renamed the Defense Security Service to be the Defense Counterintelligence and Security Agency (DCSA).  This action became effective June 20, 2019. 

DCSA will serve as the primary Federal entity for conducting background investigations for the Federal Government. DCSA will also, as a continuation of the former DSS, serve as the primary Department of Defense component for the National Industrial Security Program and will execute responsibilities relating to continuous vetting, insider threat programs, and any other responsibilities assigned to it by the Secretary of Defense.

The National Access Elsewhere Security Oversight Center (NAESOC) is a centralized DCSA Field Office providing consolidated and consistent oversight and security management over select access elsewhere companies in the National Industrial Security Program (NISP). This centralized office will handle communications, guidance, and education to NAESOC-assigned facilities and Government Partners. As a benefit to your facility being assigned to the NAESOC, we will provide continuous outreach and consistent direction. The relationships and partnerships created by the new oversight center will optimize communications, threat reporting, and vulnerability identification and mitigation.

An access-elsewhere facility is a facility that does not store classified information and all critical performance (classified or unclassified) related to their classified contract takes place at the government customer or prime contractor locations.

No. NAESOC provides oversight, support, and guidance consistent with NISPOM compliance requirements.

No. However, all new DD-254s must reflect NAESOC as the Cognizant Office.
