The National Security Agency (NSA) is part of the US government. The agency was started in 1952, and its main office is in Maryland.

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]
