National Counterintelligence and Security Center

The position of National Counterintelligence Executive (NCIX) and its supporting office, the Office of the National Counterintelligence Executive (ONCIX), were established on January 5, 2001, by a presidential directive (PDD-75) from then-President Bill Clinton; the directive also established the National Counterintelligence (CI) Board of Directors and National CI Policy Board (NCIPB) to advise the NCIX. These new counterintelligence institutions were later codified by the Counterintelligence Enhancement Act of 2002. With this reorganization, ONCIX ceased to exist as a separate organization. The National Counterintelligence Executive (NCIX) became the Director of the new NCSC. == Activities ==

The NCSC facilitates and enhances US counterintelligence efforts and awareness by enabling the CI community to better identify, assess, prioritize and counter intelligence threats from foreign powers, terrorist groups, and other non-state entities; it ensures that the CI community acts efficiently and effectively; and provides for the integration of all US counterintelligence activities. Its official mission is to: • exploit and defeat adversarial intelligence activities directed against US interests • protect the integrity of the US intelligence system • provide incisive, actionable intelligence to decision-makers at all levels • protect vital national assets from adversarial intelligence activities • neutralize and exploit adversarial intelligence activities targeting the armed forces The NCSC Director chairs the National Counterintelligence Policy Board, the principal interagency mechanism for developing national CI policies and procedures, and directs the National Counterintelligence and Security Center. The Board consists of members from the Department of Justice, (which includes the FBI), Department of Defense (including the Joint Chiefs of Staff), Department of State, Department of Energy, and the CIA. The Board may also include appointed additional members from "any other department, agency, or element of the United States Government". While NCSC does not distribute warnings of potential threats to the private sector, it works closely with the FBI's Awareness of National Security Issues and Response (ANSIR) program, with the State Department's Overseas Security Advisory Council (OSAC), as well as with the Central Intelligence Agency (CIA) to ensure that such warnings are timely made. The Office of Counterintelligence of the National Geospatial-Intelligence Agency maintains a full-time presence within NCSC. ==Leadership==
