Security Access Codes
Access to all Starfleet computer systems is highly regulated. A standard set of authorization codes have been programmed into the starboard and engineering computer cores of all ships in order to stop any undesired access to the systems.

The codes are as follows:

Alpha-Two
Unlimited access to all ship's records, systems, commands and computers.

Alpha-One
Unlimited access to all ship's records, systems and computers. No access to ship localized command functions.

Beta-Two
Unlimited access to all ship's records, systems and computers. Limited access to command functions (except if stated otherwise by Commanding Officer).

Beta-One
Unlimited access to all ship's records, and computers. Limited access to command functions (except if stated otherwise by Commanding Officer). Access to ship systems is limited to duty related functions.

Delta-Two
Limited access to all ship's records, systems, commands and computers. Access Limited to duty related functions.

Delta-One
Limited access to all ship's records, and computers. Access limited to job related functions.

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.

The access levels are as follows:

Level 5
Unlimited access to all classified, secret, top-secret, ultra-secret Starfleet or Federation documents and records.

Level 4
Limited access to all classified, secret, top-secret Starfleet or Federation documents and records. Access is limited on a 'need to know' basis.

Level 2
Limited access to all Starfleet or Federation documents and records. Access is limited on a 'need to know' basis.

Level 1

The following guidelines have been set as standard, by Starfleet Command:

 

Starfleet Rank	Access Level
Admirals and Commodores	Level 5
Captains, Commanders and certain specific personnel (duty related)	Level 4
Lieutenants, Lieutenants (j.g.) and certain specific personnel (duty related)	Level 3
