NSA (National Security Agency)

The National Security Agency (NSA) is a United States government agency responsible for signals intelligence and information assurance. Its primary role is to collect, analyze, and protect national security information, particularly regarding foreign communications and cyber threats. The NSA works to ensure the security of U.S. communications and data against foreign adversaries. It also collaborates with other intelligence agencies to provide insights that inform national security policy and operations. While the NSA plays a critical role in protecting the U.S., its activities have raised important discussions about privacy and surveillance.
