The Defense Security Service (DSS), formerly known as the Defense Investigative Service (DIS) was established on Jan. 1, 1972. DSS was created in response to President Richard M. Nixon's approval of proposals suggesting the reorganization of the national intelligence community and the creation of an "Office of Defense Investigation" to consolidate Department of Defense (DoD) personnel security investigations (PSI). Prior to this consolidation, such work was accomplished through U.S. military departments by four major DoD investigative agencies. They were: 1) the U.S. Army Intelligence Command, 2) the U.S. Army Criminal Investigative Command, 3) the Naval Investigative Service, and 4) the Office of Special Investigations, Air Force.
