The Imperial Security Bureau (ISB), also referred to as the Security Bureau or Imperial Security, was a law enforcement and intelligence agency of the Galactic Empire that was charged with matters of 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, and was larger than Imperial Intelligence.
The Imperial Security Bureau was formed by Galactic Emperor Palpatine himself as a secret police organization, dedicated to rooting out enemies of the New Order and maintaining stability throughout Imperial territories shortly after the Proclamation of the New Order. Within fourteen years, the organization grew from a handful of agents into an organization double the size of Imperial Intelligence.
Six years into the Emperor's reign, Military Intelligence agents found a cache of communications devices on the distant world of Murkhana and referred the case to the ISB who brought the matter to the Emperor and his Imperial Ruling Council, it was ultimately decided to send Wilhuff Tarkin and Darth Vader to investigate the cache, which was in reality set up by a small rebel cell, despite the ISB hoping to receive full oversight of the investigation from Military Intelligence and the Naval Intelligence Agency.
One of the ISB's top members was Agent Kallus, who worked in both the Investigation and Internal Affairs branches of the organization and searched for signs of disloyal activity or insurgency. His primary mission was to ensure it did not spread into a full-scale rebellion against the Empire. In the fifteenth year of the Empire, the Imperial Security Bureau took special interest in a crew of Lothal-based thieves, whose attacks on Imperial outposts revealed risks of sedition and gave warning signs of rebellion.
Following the destruction of the first Death Star, the ISB became busier than at any time before in its history, embarking on numerous operations to root out the growing rebellion. Operations that included a plan to sway mathematical genius Drusil Bephorin to the Empire's cause by keeping her in a sort of luxurious imprisonment on Denon. Or by setting up Project Hidden Eye, which aimed at seeding sleeper operatives across the galaxy to spread propaganda and secretly report on citizens. The project, however, was cut short due to the intervention of Commander Luke Skywalker, a hero of the enemy Rebel Alliance.
20 days after the Battle of Endor, the ISB kept information on the Emperor's contingency plan on one of it's Black Sites, the Wretch of Tayron. However, the base was then taken by Rebel Alliance General Han Solo and his Pathfinders. The base commander was unable to initiate a data purge and the Alliance was able to attain information on Operation Cinder.
Command hierarchy and administrationEdit
The Imperial Security Bureau worked closely with Emperor Palpatine throughout his reign, being led by a Bureau Chief under which served Deputy Director Harus Ison and Colonel Wullf Yularen, who often operated in conjunction with the Joint Chiefs. Members of the ISB worked from the ISB Central Office as part of the Federal District on Coruscant, while agents in the field would constantly provide intelligence updates. High-ranking ISB agents could command stormtrooper squads, override orders of civilian and military authorities, replace questionable officers and commandeer Imperial military hardware, including Star Destroyers. Some ISB agents wore a distinctive type of helmet with cheek pieces that was designed to both symbolize their status and instill fear in their opponents. Loyalty officers of the ISB were tasked with ensuring that the regular troopers and officers obeyed orders and conformed to the Imperial ideology, and were regarded with great fear and respect.
Operatives in the Surveillance branch were by far the most numerous, with its members focused on deciphering encrypted information and analyzing data to screen for potential threats against the New Order.
Interrogation was the second largest branch in the ISB, and was intent on extracting information from various lifeforms to obtain valuable information. It claimed to have a 95 percent success rate in recovering useful data from questioned subjects. To that end, the ISB notably used IT-O Interrogation Units  developed by the Imperial Department of Military Research.
The Re-Education division was focused on what some would call 'brainwashing' its subjects into supporting the Galactic Empire and its actions across the galaxy.
The Enforcement branch of the ISB served as backup for agents in the field, specially trained to provide support when necessary.
Those in Investigation used previously collected data to suppress rebel activity.
The Internal Affairs division maintained order by investigating possible instances of insubordination within the Empire, with Colonel Wullf Yularen briefly heading a division dedicated to exposing sedition within the Imperial Senate before becoming Deputy Director of the Naval Intelligence Agency.
Members of the ISB often used a specialized vocabulary to prevent outsiders from understanding their conversations. The term "auditing" was used to signal that suspects knew they were being investigated. The practice of provoking a suspect to commit a crime was referred to as "crustbusting," and interrogating a supposed innocent in hopes he or she would react suspiciously was known as "scattering." Framing a wanted suspect for a crime to make sure he or she would be arrested was referred to as "Jabba."
