The police intelligence mainframe was a computer used by Bajoran Militia stations to store and process intelligence for public security operations. During the occupation of Deep Space 9 by temporally displaced Dominion forces, a Klingon Intelligence agent attempted to bug the police intelligence mainframe in the Militia's station in the city of Hathon. The bug was found and removed, and Field Colonel Harka reportedly threatened to shoot the operative responsible if it happened again. ("Past Continuous")
