The National Security Agency

The National Security Agency (NSA) is a U.S. government agency responsible for collecting and analyzing foreign communications and intelligence to protect national security. Established in 1952, its main functions include signal intelligence (intercepting communications) and cyber defense to safeguard U.S. information systems. The NSA plays a crucial role in preventing threats to the country, such as terrorism or cyberattacks. While often associated with surveillance, its activities are governed by laws and oversight to balance security needs with privacy rights. The agency collaborates with other intelligence and law enforcement organizations to enhance national safety.
