Seal of the National Security Agency

Its stated goal is to protect the US people by

  • Worldwide "earsdropping," secretly listening to what people are saying in other countries. It monitors, collects, decodes, translates and analyses information and data. That is known as signals intelligence (SIGINT).
  • Protecting the US from eavesdropping and SIGINT spying by foreign governments and agencies, called "penetration and network warfare."[1][2] The agency does so by clandestine (secret) means,[3] such as bugging electronic systems,[4] and sabotaging their computer networks with viral software.[5][6]
