As a branch of Strategic Operations, Starfleet Security agency is responsible for ship and personnel security aboard all Starfleet vessels and installations, as well as select United Federation of Planets outposts, vessels, and facilities.
It is the role of the Security Officer to protect the vessel/facility as well as its crew in addition to maintaining and enforcing Starfleet Security regulations, procedures and policies. In addition, this agency is responsible for security clearances of all Starfleet and Federation personnel.
Starfleet Security, in close cooperation with Starfleet Intelligence, is responsible for counter-intelligence operations.
In conjunction with Federation Security, the agency is also responsible for the security of the Federation President, as well as members of the Federation Council and visiting alien dignitaries.
The jurisdiction of Starfleet Security extends only to Starfleet vessels, stations and facilities and the Starfleet personnel stationed therein. As a branch of a naval organization, Starfleet Security does not have any significant jurisdiction over civilians. In situations where a civilian commits a crime within a Starfleet facility, Starfleet Security has authority to detain the accused until such time as they can be remanded to the appropriate civilian authorities.
Jurisdictional authority should not be interpreted as being limited to the vessel on which an officer serves. Though a visiting officer must always report to the department head, a security officer serving aboard Starbase Zetari has as much jurisdictional authority for arrest and detention aboard the USS Archer.
Starfleet Security has absolutely no jurisdiction on non-Starfleet colonies or installations, regardless of their status as Federation members.
