Starfleet Protocol: Command Action Zero

Command Action Zero is a top-secret Starfleet protocol designed to prevent starships and their crews from going "rogue". After the successful overthrow of the corrupt Starfleet brass in 2401, Starfleet officials eventually decided that they needed a safeguard in place to prevent similar events from happening. In the event that the sovereignty of the Federation is challenged or starship commanders seem to be unstable and untrustworthy, Starfleet activates Command Action Zero. Command Action Zero can be used to target individual ships, groups of ships, or the entire fleet.

Command Action Zero locks out all computer access terminals, command protocols, and voice commands. No computer access, whether via wall panels or terminals, is allowed for targeted ships. This ensures that the ship will carry out the orders Starfleet sends it to the letter.

Once activated, Command Action Zero can only be terminated by Starfleet Command. All orders to ships operating under Command Action Zero are sent via a master hub on a secret subspace frequency that is heavily encrypted.

Command Action Zero is impossible to hack, as it is not directly present on the ship. The subspace frequency used is coded to be invisible to anyone looking for it, blending in with background "noise" and radiation under its many levels of encryption.
