The NSA is also tasked with the protection of U. S. communications networks and information systems. The NSA relies on a variety of measures to accomplish its mission, the majority of which are clandestine.

The NSA is entrusted with providing assistance to, and the coordination of, SIGINT elements for other government organizations which are prevented by law from engaging in such activities on their own. As part of these responsibilities, the agency has a co located organization called the Central Security Service CSS, which facilitates cooperation between the NSA and other U.

HistoryeditFormationeditThe origins of the National Security Agency can be traced back to April 2. U. S. Congress declared war on Germany in World War I. A code and cipher decryption unit was established as the Cable and Telegraph Section which was also known as the Cipher Bureau. It was headquartered in Washington, D. C. and was part of the war effort under the executive branch without direct Congressional authorization. During the course of the war it was relocated in the armys organizational chart several times.

Jointly funded by the Army and the State Department, the Cipher Bureau was disguised as a New York Citycommercial code company it actually produced and sold such codes for business use. Its true mission, however, was to break the communications chiefly diplomatic of other nations. Its most notable known success was at the Washington Naval Conference, during which it aided American negotiators considerably by providing them with the decrypted traffic of many of the conference delegations, most notably the Japanese. The Black Chamber successfully persuaded Western Union, the largest U. S. telegram company at the time, as well as several other communications companies to illegally give the Black Chamber access to cable traffic of foreign embassies and consulates.

The AFSA was tasked to direct Department of Defense communications and electronic intelligence activities, except those of U. S. military intelligence units. However, the AFSA was unable to centralize communications intelligence and failed to coordinate with civilian agencies that shared its interests such as the Department of State, Central Intelligence Agency CIA and the Federal Bureau of Investigation FBI. In December 1. 95. President Harry S. Truman ordered a panel to investigate how AFSA had failed to achieve its goals. The results of the investigation led to improvements and its redesignation as the National Security Agency. The agency was formally established by Truman in a memorandum of October 2.
