FSB

The counterintelligence organization of Russia is its Federal Security Service (Russian: ФСБ, Федера́льная слу́жба безопа́сности; Federalnaya Sluzhba Bezopasnosti or FSB). Its immediate ancestor under the Soviet Union was the Committee for State Security (Russian: Комитет государственной безопасности; Komityet Gosudarstvennoy Bezopasnosti or KGB). The KGB, in turn, was one of a long sequence of "Organs of State Security" under the Soviet government, and can trace its origin to the Okhrana of Czarist Russia.
