Chief of security

The security chief (or chief of security) is the officer in charge of the security division of a starship or starbase.

In the Earth Starfleet, the armory officer was in charge of a ship's security department.

In the mid-23rd century Federation Starfleet a security chief, like Lieutenant Commander Giotto of the USS Enterprise, was not necessarily a bridge officer (TOS:"The Devil in the Dark").

In the 2270s, the role of security chief was combined with that of the chief tactical officer. The chief tactical officer could be a separate position or be combined with that of helmsman or navigator (Star Trek: The Motion Picture, Star Trek V: The Final Frontier, Star Trek VI: The Undiscovered Country).

In the 24th century, with helm and navigation consolidated in the new flight controller position, the chief tactical officer fulfilled the role of security chief (TNG:"Encounter at Farpoint").

On starbases, the chief of security is usually a separate position from the tactical officer.
