The National Security Agency/Central Security Service (NSA/CSS) is America's codemakers and codebreakers. NSA was created in 1952 by President Harry S. Truman to unite military and civilian codemakers and codebreakers. CSS was created in 1972 by NSA Director VADM Noel Gayler, USN, and includes the cryptologic units of each of the military services: Army, Navy, Marine Corps, Air Force, and Coast Guard. These units are called Service Cryptologic Elements (SCEs). The Director of NSA is also the Chief of the CSS. Our current Director is GEN Keith B. Alexander, USA. Our current Deputy Director is Mr. John C. (Chris) Inglis.
Together, NSA and CSS provide the technology (Information Assurance) and the information (Signals Intelligence) our Nation's leaders and warfighters need to get their jobs done. Without NSA/CSS, they wouldn't be able to talk to one another without the bad guys listening and they wouldn't be able to figure out what the bad guys were planning. The combination of foreign Signals Intelligence and Information Assurance, called Cryptology, gives the United States an advantage over its enemies.
