US National Security Agency (NSA)

The National Security Agency (NSA) is a U.S. government agency responsible for collecting and analyzing foreign communications and intelligence to protect national security. It focuses on monitoring electronic communications, including phone calls and internet data, to prevent threats such as terrorism and cyberattacks. The NSA also works on securing U.S. government communications and information systems. While it plays a crucial role in national defense, its surveillance practices have raised privacy concerns and debates about the balance between security and individual rights.
