The National Security Agency is an intelligence organization of the United States government, responsible for global monitoring, collection, and processing of information and data for foreign intelligence and counterintelligence purposes, a discipline known as signals intelligence.
Signals intelligence is intelligence-gathering by interception of signals, whether communications between people or from electronic signals not directly used in communication.

Inside NSA - The National Security Agency - Documentary by Francis Hector
NSA is concurrently charged with protection of U.S. government communications and information systems against penetration and network warfare.
The government of the United States of America is the federal government of the republic of fifty states that constitute the United States, as well as one capital district, and several other territories.

Although many of NSA's programs rely on "passive" electronic collection, the agency is authorized to accomplish its mission through active clandestine means, among which are physically bugging electronic systems and allegedly engaging in sabotage through subversive software.
A covert listening device, more commonly known as a bug or a wire, is usually a combination of a miniature radio transmitter with a microphone.
Sabotage is a deliberate action aimed at weakening a polity or corporation through subversion, obstruction, disruption or destruction.
Moreover, NSA maintains physical presence in a large number of countries across the globe, where its Special Collection Service inserts eavesdropping devices in difficult-to-reach places.
The Special Collection Service is a highly classified joint U.S. Central Intelligence Agency-National Security Agency program charged with inserting eavesdropping equipment in difficult-to-reach places, such as foreign embassies, communications centers, and foreign government installations.
Eavesdropping is secretly listening to the private conversation of others without their consent, as defined by Black's Law Dictionary.
SCS collection tactics allegedly encompass "close surveillance, burglary, wiretapping, breaking and entering".
Unlike the Defense Intelligence Agency and the Central Intelligence Agency, both of which specialize primarily in foreign human espionage, NSA does not unilaterally conduct human-source intelligence gathering, despite often being portrayed so in popular culture.
The Central Intelligence Agency is a civilian foreign intelligence service of the United States federal government, tasked with gathering, processing and analyzing national security information from around the world, primarily through the use of human intelligence.

Instead, NSA is entrusted with assistance to and coordination of SIGINT elements at other government organizations, which are prevented by law from engaging in such activities without the approval of the NSA via the Defense Secretary.
As part of these streamlining responsibilities, the agency has a co-located organization called the Central Security Service, which was created to facilitate cooperation between NSA and other U.S. military cryptanalysis components.
The Central Security Service is an agency of the United States Department of Defense, which was established in 1972 to integrate the National Security Agency and the Service Cryptologic Elements of the United States Armed Forces in the field of signals intelligence, cryptology and information assurance at the tactical level.
Additionally, the NSA Director simultaneously serves as the Commander of the United States Cyber Command and as Chief of the Central Security Service.
United States Cyber Command is an armed forces sub-unified command subordinate to United States Strategic Command.
Originating as a unit to decipher coded communications in World War II, it was officially formed as the NSA by President Harry S. Truman in 1952.
World War I, also known as the First World War, or the Great War, was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918.
In cryptography, a cipher is an algorithm for performing encryption or decryption—a series of well-defined steps that can be followed as a procedure.
World War II, also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier.
Since then, it has become one of the largest U.S. intelligence organizations in terms of personnel and budget, operating as part of the Department of Defense and simultaneously reporting to the Director of National Intelligence.
The Director of National Intelligence is the United States government official – subject to the authority, direction, and control of the President – required by the Intelligence Reform and Terrorism Prevention Act of 2004 to:
NSA surveillance has been a matter of political controversy on several occasions, such as its spying on anti-Vietnam war leaders or economic espionage.
Industrial espionage, economic espionage, corporate spying or corporate espionage is a form of espionage conducted for commercial purposes instead of purely national security.
In 2013, the extent of some of the NSA's secret surveillance programs was revealed to the public by Edward Snowden.
Edward Joseph Snowden is an American computer professional, former Central Intelligence Agency employee and former contractor for the United States government who copied and leaked classified information from the National Security Agency in 2013 without prior authorization.
According to the leaked documents, the NSA intercepts the communications of over a billion people worldwide, many of whom are American citizens, and tracks the movement of hundreds of millions of people using cellphones.
Internationally, research has pointed to the NSA's ability to surveil the domestic Internet traffic of foreign countries through "boomerang routing".
