National Security Agency (NSA)

The National Security Agency (NSA) is a U.S. government agency responsible for collecting and analyzing foreign intelligence data, primarily focusing on signals intelligence. It plays a crucial role in national defense by monitoring communications and activities that could pose threats to national security. The NSA also protects U.S. government communications and information systems from cyber threats. While its work is vital for safeguarding the country, it often raises concerns about privacy and civil liberties, as it operates largely behind the scenes and handles sensitive information.
