Starfleet Security is the branch of the Federation Starfleet responsible for security aboard all Federation starships and at all Federation starbases and outposts. In addition, Starfleet Security is responsible for providing security at all Federation government facilities, such as the Palais de la Concorde. Starfleet Security is responsible for maintaining and enforcing Starfleet regulations, procedures and policies on all Starfleet and affiliated facilities, outposts, and vessels, and is responsible for setting security clearances for all Starfleet and government personnel and facilities. Starfleet Security often works in conjunction with Starfleet Intelligence. (TNG episode: "The Drumhead", et. al.)
