Not everything over there is fully functional yet, and the internal links still point to this blog, and will for the indefinite future.So all the old material will be left here for archival purposes, with comments turned off.The National Security Agency (NSA) is a national-level intelligence agency of the United States Department of Defense, under the authority of the Director of National Intelligence. Unlike the CIA and the Defense Intelligence Agency (DIA), both of which specialize primarily in foreign human espionage, the NSA does not publicly conduct human-source intelligence gathering.The NSA is responsible for global monitoring, collection, and processing of information and data for foreign intelligence and counterintelligence purposes, specializing in a discipline known as signals intelligence (SIGINT). The NSA is entrusted with providing assistance to, and the coordination of, SIGINT elements for other government organizations - which are prevented by law from engaging in such activities on their own. To further ensure streamlined communication between the signals intelligence community divisions, the NSA Director simultaneously serves as the Commander of the United States Cyber Command and as Chief of the Central Security Service. Originating as a unit to decipher coded communications in World War II, it was officially formed as the NSA by President Harry S. SCS collection tactics allegedly encompass "close surveillance, burglary, wiretapping, [and] breaking and entering". The NSA, alongside the Central Intelligence Agency (CIA), maintains a physical presence in many countries across the globe; the CIA/NSA joint Special Collection Service (a highly classified intelligence team) inserts eavesdropping devices in high value targets (such as Presidential palaces or embassies).
According to the leaked documents, the NSA intercepts and stores the communications of over a billion people worldwide, including United States citizens.
The documents also revealed the NSA tracks hundreds of millions of people's movements using cellphones metadata. and was part of the war effort under the executive branch without direct Congressional authorization. At that point, the unit consisted of Yardley and two civilian clerks.
Internationally, research has pointed to the NSA's ability to surveil the domestic Internet traffic of foreign countries through "boomerang routing". A code and cipher decryption unit was established as the Cable and Telegraph Section which was also known as the Cipher Bureau. During the course of the war it was relocated in the army's organizational chart several times. It absorbed the navy's Cryptanalysis functions in July 1918. Army cryptographic section of military intelligence, known as MI-8, in 1919, the U. government created the Cipher Bureau, also known as Black Chamber.
The origins of the National Security Agency can be traced back to April 28, 1917, three weeks after the U. World War I ended on November 11, 1918, and the army cryptographic section of Military Intelligence (MI-8) moved to New York City on May 20, 1919, where it continued intelligence activities as the Code Compilation Company under the direction of Yardley. The Black Chamber was the United States' first peacetime cryptanalytic organization.
Jointly funded by the Army and the State Department, the Cipher Bureau was disguised as a New York City commercial code company; it actually produced and sold such codes for business use.
