All Starfleet starships and bases are fitted with advanced computer systems which can perform many tasks and store masses of information. Access to these computers, and the data they contain, is strictly regulated, so that only authorised personnel can perform certain tasks, or access certain data files.
Computer Access Codes
Access to all Starfleet computer systems is highly regulated. A standard set of authorization codes has been programmed into the computer cores of all starships and bases in order to stop any undesired access to the systems.
There are 6 types of access codes:
Alpha-2
Unlimited access to all ship's records, systems, commands and computers.
Alpha-1
Unlimited access to all ship's records, systems and computers. No access to ship localized command functions.

Beta-1

Different officers on a starfleet vessel, have varying levels of security access, depending on their level of authority or their duties. The following common positions, have been assigned standard levels of security access. The final decision on an officers level of security access, however, is decided by that officer's Commanding Officer.
The Commanding Officer reserves the privilege of permitting limited access to any unspecified section of the ship to any personnel whose functions, in the eyes of the CO, require it.
Alpha-2: Commanding Officer, First Officer, Executive Officer, Security/Tactical Chief
Alpha-1 or Beta-2: Chief Operations Officer, Chief Engineering Officer
