Imperial Security Bureau
The Imperial Security Bureau (ISB), also referred to as the Imperial Security Office or the Imperial Secret Service, was a law enforcement and intelligence agency of the Galactic Empire that was charged with matters of internal state security and ensuring the loyalty of citizens to the Empire. Aside from that, it happened to be one of the many umbrella organizations under the greater Commission for the Preservation of the New Order (COMPNOR), and was larger than its sister agency Imperial Intelligence.
