A security agency is a governmental organization which conducts intelligence activities for the internal security of a nation.
 They are the domestic cousins of foreign intelligence agencies, and typically conduct counterintelligence to thwart other countries' foreign intelligence efforts.
 For example, the United States Federal Bureau of Investigation (FBI) is the internal intelligence, security and law enforcement agency, while the Central Intelligence Agency (CIA) is an external intelligence service, which deals primarily with intelligence collection overseas.
 A similar relationship exists in Britain between MI5 and MI6.
The Rosenholz files are a collection of 381 CD-ROMs containing 280,000 files with information on persons who were sources and targets or employees and helpers in the focus of the "Hauptverwaltung Aufklärung" ("HVA", Main Directorate for Reconnaissance), the primary foreign intelligence agency of the former German Democratic Republic (East Germany).
 At the beginning one thought that the files mostly contain the real names of agents who worked for the HVA in former West Germany.
 Later it came clear that at least 90% of the persons never worked for or with the HVA.

 The First Chief Directorate was formed within the KGB directorate in 1954, and after the collapse of the Soviet Union was renamed as the Central Intelligence Service and finally the Foreign Intelligence Service (SVR RF).
 Although the agency "SVR" restyle in 1991 implies a generic overseas surveillance activity, the primary foreign intelligence service in Russia and the Soviet Union has been the GRU, a military intelligence organization and special operations force shrouded in secrecy, most famed for stealing the blueprints of the atomic bomb during the Manhattan Project and barring entry into its headquarters to anyone, even the leader of the Soviet Union proper, without a formal authentication.
