NSA

The National Security Agency (NSA) is a U.S. government agency responsible for monitoring and analyzing foreign communications and intelligence to protect national security. It focuses on signals intelligence, which involves intercepting and decrypting electronic communications, such as phone calls and internet traffic. The NSA also works to secure U.S. government communications and information systems. Established in 1952, the agency operates largely in secrecy, and its activities have raised debates about privacy, security, and surveillance, especially following revelations about extensive data collection practices. Ultimately, the NSA plays a crucial role in safeguarding the nation against foreign threats.
