From Wikipedia, the free encyclopedia.
Sluzba Bezpieczenstwa (SB) was, under the communists, the name of the Polish intelligence agency and security police. It was created in 1956 to replace the Urzad Bezpieczenstwa. It was responsible for intelligence, counterintelligence, state security and suppression of political opposition until its replacement by the Urzad Ochrony Panstwa in 1990 after the fall of communism.
