Security

Star Fleet Security is a branch of Star Fleet responsible for maintaining security, with its headquarters at Star Fleet Security Command

In the early 2150s, Star Fleet Security was a section of United Earth's Star Fleet that had at least one branch based on Earth in the Sol sector.

Harris served in Star Fleet Security until 2149, when his service abruptly ended. In 2154, Commander Collins was a security officer who worked for Star Fleet Security. The department scanned for DNA and ionization traces to search for Doctor Phlox, who had been kidnapped outside Madame Chang's Mandarin Cafe in San Francisco on Earth.

Following the foundation of the United Federation of Planets, Star Fleet Security was not only responsible for Star Fleet security, but also some Federation outposts, starships, and facilities. In this function, they act in ways analogous to local and regional police agencies, but Star Fleet Security's mandate extends much farther than that. The agency is responsible for maintaining and enforcing Star Fleet Security regulations, procedures and policies on all Star Fleet and affiliated facilities, outposts, and vessels. In addition, this agency is responsible for security clearances of all Star Fleet/UFP personnel.

The agency, in close cooperation with Star Fleet Intelligence, is also responsible for counter-intelligence operations. The agency is also responsible for the security of the Federation President, as well as members of the Federation Council and visiting alien dignitaries.

In 2367, Vice Admiral Thomas Henry was the Chief of Star Fleet Security. He evidently was a firm defender of personal liberty in addition to his primary duties when he punished Admiral Norah Satie for leading a baseless political witch-hunt on the Enterprise. By 2370, Admiral Raner was serving as head of Star Fleet Security Command.

In 2369, the Star Fleet Security officer George Primmin was sent to Deep Space 9 to help protect a shipment of deuridium.

Star Fleet Security often sent Odo criminal activity reports.

A Star Fleet Security investigation determined that Ambassador Krajensky had been kidnapped or killed by the Dominion on his way to Risa.

In a situation of emergency, officers may be assigned to planetary security. In 2372 Benjamin Sisko was assigned Chief of Star Fleet Security on Earth by Admiral Leyton.

After Sisko was attacked by a member of the Cult of the Pah-wraiths in early 2375, he gave a statement to Star Fleet Security.

Aboard Star Fleet-run facilities and vessels, security was one of the most important divisions in the 23rd and 24th centuries, combining the armory and MACO functions of the 22nd century. Security personnel served functions both defensive and offensive, ranging from security patrols on board a starship, to guarding prisoners, to firing the ship's weapons, to providing protection during landing party/away team missions, and more. In the 24th century the officer in charge of security on a starship was given the title of Security Chief.
