The South African Bureau for State Security (incorrectly given the abbreviation B.O.S.S. by journalists, Afrikaans: Buro vir Staatsveiligheid) was established in 1969 and replaced by the National Intelligence Service (NIS) in 1980. The Bureau's job was to monitor national security. It was headed by Hendrik van den Bergh.
The Bureau is perhaps most infamous for its involvement in the Information Scandal or Muldergate Scandal, when South African Government funds were used to establish a pro-National Party English language newspaper, The Citizen. This scandal was the main reason for its replacement in 1980.
