The National Counterintelligence and Security Center (NCSC) leads national counterintelligence (CI) for the United States government. It is part of the Office of the Director of National Intelligence (ODNI). History 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 decision 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. ONCIX replaced the National Counterintelligence Center, which was created in 1994 in response to the arrest of CIA mole Aldrich Ames. These new counterintelligence institutions were later codified by the Counterintelligence Enhancement Act of 2002. The 2004 Intelligence Reform and Terrorism Prevention Act (IRTPA), passed to implement many of the recommendations of the 9/11 Commission, placed the NCIX and ONCIX, which coordinated Intelligence Community (IC) counterintelligence, inside the new Office of the Director of National Intelligence (ODNI), which itself coordinated all IC activities generally. In November 2014, the Director of National Intelligence established NCSC by combining ONCIX with the Center for Security Evaluation, the Special Security Center and the National Insider Threat Task Force, to effectively integrate and align counterintelligence and security mission areas under a single organization. With this reorganization, the ONCIX ceased to exist as a separate organization. The National Counterintelligence Executive (NCIX) became the Director of the new NCSC. Role The ONCIX 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; 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 National Counterintelligence Executive 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. While ONCIX 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, the State
