Imperial Security Bureau/Legends

The Imperial Security Bureau (also called Imperial Security or just ISB) was a key intelligence organization of the Galactic Empire under Emperor Palpatine. It was separate from, larger than, and often rival to Imperial Intelligence.

In addition to operating as a standard intelligence agency, the ISB was a part of the Commission for the Preservation of the New Order, or COMPNOR, charged with maintaining morale and loyalty among members of the Imperial military. Lord Crueya Vandron, one of Palpatine's closest advisors, was effectively the head of both COMPNOR and the ISB.

The ISB stationed moles among the officers of all capital ships in the Imperial Starfleet; their duty was to report on any possibly treasonous activities or sentiments present among others of the ship's crew (especially the commander), and to execute them if they acted upon them.

The ISB also was responsible for wiping out any memories of the Jedi Order. They destroyed the collection of Jedi antiquities on Obroa-skai.

Several key ISB members died aboard the Death Star. Such as Colonel Wolf, and a spy-droid used to investigate Core World secret bases of the Alliance.
