The Mitrokhin Commission was an Italian parliamentary commission set up in 2002 to investigate alleged KGB ties of some Italian politicians.
The KGB, an initialism for Komitet Gosudarstvennoy Bezopasnosti (Russian: "Комите́т Госуда́рственной Безопа́сности" ("КГБ") ; ] ), translated in English as Committee for State Security, was the main security agency for the Soviet Union from 1954 until its break-up in 1991, as a direct successor of such preceding agencies as Cheka, NKGB, NKVD and MGB, a committee was attached to the Council of Ministers.
 It was the chief government agency of "union-republican jurisdiction", acting as internal security, intelligence and secret police.
 Similar agencies were constituted in each of the republics of the Soviet Union aside from Russia, and consisted of many ministries, state committees and state commissions.
The Swedish Security Service (Swedish: "Säkerhetspolisen" , abbreviated Säpo, until 1989 " Rikspolisstyrelsens säkerhetsavdelning" abbreviated RPS/Säk) is a Swedish government agency organised under the Ministry of Justice.
 It operates like a security agency responsible for counter-espionage, counter-terrorism, the protection of dignitaries and the constitution.
 The Swedish Security Service is also tasked with investigating crimes against national security and terrorist crimes.
 Its main mission, however, is to prevent crime, and not to investigate them.
 Crime prevention is to a large extent based on information acquired via contacts with the regular police force, other authorities and organisations, foreign intelligence and security services, and with the use of various intelligence gathering activities, including interrogations, telephone tapping, covert listening devices and hidden surveillance cameras.
 The Service was, in its present form, founded in 1989, as part of the National Police Board and became an autonomous police agency January 1, 2015.
 National headquarters are located at Bolstomtavägen in south-east Solna since 2014, drawing together personnel from five different locations into a single 30000 m2 HQ facility.
The United States Army Security Agency (ASA) was the United States Army's signals intelligence branch.
 The Latin motto of the Army Security Agency was "Semper Vigilis" (Vigilant Always), which echoes the declaration, often misattributed to Thomas Jefferson, that "" The Agency existed between 1945 and 1976 and was the successor to Army signals intelligence operations dating back to World War I.
 ASA was under the operational control of the Director of the National Security Agency (DIRNSA), located at Fort Meade, Maryland; but had its own tactical commander at Headquarters, ASA, Arlington Hall Station, Virginia.
 Besides intelligence gathering, it had responsibility for the security of Army communications and for electronic countermeasures operations.
 In 1977, the ASA was merged with the US Army's Military Intelligence component to create the United States Army Intelligence and Security Command (INSCOM).
The National Security Agency (Egyptian Arabic: قطاع الأمن الوطني‎ ‎ , "Ketaʿ El Amn El Watani" , also Homeland Security) is an Egyptian security service, the main domestic security agency of Egypt and the successor of the State Security Investigations Service (Egyptian Arabic: مباحث أمن الدولة‎ ‎ "Mabaḥith Amn El Dawla" ).
 (Two other security agencies are the Military Intelligence and the General Intelligence Directorate which traditionally specializes in foreign intelligence gathering.)
 Its main responsibilities are counter-intelligence, internal and border security, counter-terrorism, and surveillance.
 The agency is under the jurisdiction of the Interior Ministry and is headquartered in Cairo.
 It "remains the most visible" of Egypt's security agencies and according to one estimate has about "100,000 employees and at least as many informants".
Vasili Nikitich Mitrokhin (Russian: Васи́лий Ники́тич Митро́хин ; March 3, 1922 – January 23, 2004) was a major and senior archivist for the Soviet Union's foreign intelligence service, the First Chief Directorate of the KGB, who defected to the United Kingdom in 1992 after providing the British embassy in Riga with a vast collection of KGB files, which became known as the Mitrokhin Archive.
 The intelligence files given by Mitrokhin to the MI6 exposed an unknown number of Russian agents, including Melita Norwood.

United States Army Security Agency (USASA) Field Station Augsburg was the site of a Wullenweber AN/FLR-9 radio direction finder, established during the Cold War.
 Field Station Augsburg was located on Gablingen Kaserne, near the village of Gablingen just north of Augsburg in Bavaria, West Germany.
 It was one of nearly 20 Field Stations positioned strategically around the world by U.S. Armed Forces during the Cold War.
 Field Station Augsburg opened in 1971 and closed in 1998, at which time it was turned over to the German government.
 It was owned and managed by the National Security Agency and manned by the U.S. Army Security Agency (USASA), which later became U.S. Army INSCOM (Intelligence and Security Command), in conjunction with other branches of the U.S. Military and various allied forces.
 Personnel assigned to Field Station Augsburg were composed of individuals who scored high enough on the Army entrance exams to be classified as "ST" or a skilled technician, which is the Army's top-ranked job category.
 Field Station Augsburg was manned 24 hours a day, by means of rotating shifts, as part of the effort to ensure the safety and security of the U.S., as are any country's intelligence operations.
 There was a saying in the '70s that if the intelligence units were able to effectively do their job, the combat units wouldn't have to do theirs.
 The mission of USAFSA was to monitor the communications of Cold War enemy nations, their allies, and client states around the world.
 The information gathered was time-sensitive and, based on its importance and classification, that information was collected, analyzed and passed through intelligence channels on a "real-time" basis.
