The United States National Security Agency (NSA) is a federal intelligence agency under the jurisdiction of the Department of Defense. Its primary role is to protect national security by safeguarding U.S. information and information systems, as well as by collecting, deciphering, and analyzing communications and foreign intelligence in support of U.S. political and military leadership. The NSA was established in 1952, combining several existing signal intelligence units into one central agency. It operates under the oversight of Congress, with the Director of National Intelligence as its head. Its activities are regulated by laws such as the Foreign Intelligence Surveillance Act and the USA Freedom Act. The NSA is known for its significant role in global cybersecurity and encryption standards. However, it has been subject to controversy due to allegations of overreach in its surveillance activities.
