Editing Security Service (Poland) (section)

==Tasks and organizational structure==
The tasks of the Security Service were identical to that of its predecessors (MBP, UB and KdsBP): to protect the communist system in the country (and beyond) through control and penetration into all structures of social life in Poland and abroad. The centrally-based MSW was divided into departments, bureaus, sections and directorates. The following was observed in the SB after the agency was founded:<ref>Aparat bezpieczeństwa w Polsce.
