(NSA) National Security Agency

The National Security Agency (NSA) is a U.S. intelligence organization responsible for the collection, analysis, and dissemination of signals intelligence (SIGINT) to support national security objectives. It is headquartered in Fort Meade, Maryland and is part of the Department of Defense. The NSA's mission is to protect the U.S. national security systems and to produce foreign signals intelligence in support of U.S. national security objectives. The NSA has been in the news in recent years due to its controversial surveillance programs, which have raised questions about privacy and civil liberties.
