Police officers could advance and attain the ranks of Master Sergeant, Lieutenant, Captain, and Major. Officers could also advance to become CorSec Inspectors. CorSec was headed by a Director. During the reign of the Galactic Empire, it was common for the organization's divisions to be observed by a Imperial Liaison officer.
The Tactical Response Team was an elite paramilitary branch of CorSec, and it had its own Intelligence service. CorSec also had its own Smuggling Interdiction Division and Animal Control Division as well as a Special Operations Division. There was a false, but persistent, myth that all CorSec officers were given quotas of traffic tickets to hand out.
CorSec employed agents of many skills, including computer experts, technicians, commandos, security guards, diplomats and snipers. The agency was extremely efficient, and few criminals were able to operate for extended periods of time on Corellia before a CorSec agent would infiltrate the organization.
Undercover officers were allowed to participate in crimes against property, but could not aid in or even allow crimes against people. All undercover agents were told that they did not have to do anything they morally or philosophically objected to.

The Corellian Security Force was an extremely self-sufficient organization, though during the reign of the Galactic Empire, Kirtan Loor was an Imperial Intelligence liaison with the organization. During that time the goals of CorSec matched those of the Empire, which included hunting down slicers, terrorists and Rebels. During the Great Jedi Purge, CorSec also aided Darth Vader and his agents in tracking down and hunting Jedi.
During the Galactic Civil War, CorSec captured the illegally-modified Short Hauler Nova Whisper, up till then property of the privateer Dharus. CorSec wanted to use the ship as a bait for criminals and left the customizations on it. The ship was assigned to CorSec's vehicle pool until it was hijacked by its pilot, Delt Nerris.
In 7 ABY it was dissolved upon order of Diktat Daclif Gallamby, and the new Public Safety Service (PSS) was formed to replace it. However, by the time of the Yuuzhan Vong War it had been reconstituted, possibly after Thrackan Sal-Solo became governor-general. In the Second Galactic Civil War it was under the control of the Ministry of War.
