  1. United States National Security Agency

    The National Security Agency is a U.S. intelligence agency responsible for the production and management of signals intelligence and information assurance for the United States government. Originating as a unit to decipher code communications in World War I, it was officially formed as the NSA by President Truman in 1952. Since then, it has become one of the largest of U.S. intelligence organizations in terms of personnel and budget, operating under the jurisdiction of the Department of Defense and reporting to the Director of National Intelligence. The NSA is tasked with the global monitoring, collection, decoding, translation and analysis of information and data for foreign intelligence and counterintelligence purposes, including surveillance of targeted individuals in U.S. territory. The agency is authorized to accomplish its mission through clandestine means, among which are bugging electronic systems and allegedly engaging in sabotage through subversive software. The NSA is also responsible for the protection of U.S. government communications and information systems. As part of the growing practice of mass surveillance in the United States, the NSA collects and stores all phone records of all American citizens.
