INTRODUCTION• The National Security Agency (NSA) is a U.S. intelligence agency

responsible for providing the United States government with encrypted communications and the reading of encrypted communications of other nations.

• The NSA also creates and maintains secure computer network operations for the U.S. Government and prepares for network warfare.

• Originating as a unit to decipher code communications in World War II, 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.

HISTORY• In the early 20th century, the US military faced a new challenge with

the increased use of radio technology for military operations.

• Cryptology, the study of codes and how to crack them, emerged as an important tool for military intelligence.

• It was for this reason that during World War I, the US Army created the Cipher Bureau within the Military Intelligence Division to assist with radio intelligence.

• It was re-established as the core of the Signal Security Agency, and played a key role in intelligence gathering during the war.

• The US military and intelligence agencies transformed in the aftermath of World War II.

• In 1947, the National Security Act passed and created the Central Intelligence Agency and the National Security Council to combat new threats to American security.

• In 1949, the Armed Forces Security Agency was created within the Department of Defense for the purposes of organizing electronic communication throughout civilian agencies.
