The National Security Agency (NSA) was established in 1952 and the Central Security Service (CSS) was established in 1972. NSA/CSS is under the authority, direction, and control of the Under Secretary of Defense for Intelligence. As the Nation's cryptologic organization, NSA/CSS employs the Nation's premier codemakers and codebreakers. It ensures an informed, alert, and secure environment for U.S. warfighters and policymakers. The cryptologic resources of NSA/CSS unite to provide U.S. policymakers with intelligence information derived from America's adversaries while protecting U.S. Government signals and information systems from exploitation by those same adversaries.
