Command Codes

Command codes are specialized access codes used to access key command level functions. Such functions include most starship operations but more specifically allow personnel to access critical diagnostic, operational, and override functions of the main computer. All key functions are operated by command code.

Multifactor Authentication

Access to command functions is obtained through multifactor authentication schemes, these schemes utilize one or more of the following authentication parameters:

• Something You Know (i.e. access codes or username / password)
• Something You Have (i.e. physical access card or physical access key-fob)
• Something You Are (i.e. DNA, voice print, finger print, retinal scan, or other personally unique biometric data)

Access Cards / Fobs

In the case of a physical access card to key-fob, these require to be scanned by the computer or the short-lived alpha-numeric code for the device provided be input before access can be granted. When a key-fob produced a unique code, it lasts for 20 seconds, then it changed to a random or otherwise unpredictable code. Even if the proper access code or biometric data is given, if such a code or access is not available.

Combadge

A combadge provides multiple functions for the authentication process. For one, it can generate two forms of authentication. The device is equipped with a DNA scanner which, when attached close to the body (such as on clothes), is able to scan the wearers DNA and transmit verification data to the main computer. Secondly the device generates a 4096 bit authentication key every 20 seconds, this key is generated by the main computer as well. If the computers key and the combadge key both match, then this provides the same kind of authentication as key-fob.

Fourth Factor Authentication

Commands which require four factors of authentication require all three factors above and an additional biometric verification, usually voice print and DNA / retinal scan match before access is granted.

Command Levels

Command codes are given most often by rank, but specialized access may be given by someone of a given level, or above, overriding default access. Such instances are most often used with Non-Commissioned Officers who require specialized access but do not have specific rank. Usage of such access overrides is required to be audited but security personnel and reported on to the commanding officer or flag officer who originally granted the access. The table below indicates default access levels determined by rank.

Level	Granted To	Code Complexity	Authentication	Functions
Level 0	Civilian	6 Token Code	Single Factor	Basic library computer access Internal communications Unsecured external communications Access to unsecured areas
Level 1	Enlisted	8 Token Code	Single Factor	Secure access to BlueNet Secure access to all communications Access to secure areas Manual override access to tertiary systems Place Level 1 access lockouts.
Level 2	Commissioned Officers	8 Token Code	Two Factor	Advanced diagnostic control Manual override of secondary systems Override Level 1 access lockouts Place Level 2 access lockouts
Level 3	Department Heads	8 Token Code	Two Factor	Command functions Manual override of primary systems Provide Secondary Authorization for Self Destruct Override of Level 2 access lockouts Place level 3 access lockouts
Level 4	Executive Officer	8 Token Code	Three Factor	Override command functions Provide Primary Authorization for Self Destruct Access secure mission data Override of Level 3 access lockouts Place level 4 access lockouts
Level 5	Commanding Officer	8 Token Code	Three Factor	Localize command functions Manual override to any system under his/her command authority View classified data pertaining to current mission View eyes-only data pertaining to vessel operations Override of Level 4 access lockouts Place level 5 access lockouts
Level 6	Temporal Operatives	10 Token Code	Three Factor	Authorize use of time travel Access classified information related to temporal anomalies and current temporal operations Override operation of time travel related systems Override of Level 5 access lockouts Place level 6 access lockouts
Level 7	Flag Officers	10 Token Code	Four Factor	Access all mission data for any operation currently underway Access all mission data for past missions Access all mission data for missions currently in the planning stage Authorize changes in asset deployments Assign or remove command authority Recall temporal assets during field operations Override of Level 6 access lockouts Place level 7 access lockouts
Level 8	Fleet Admiral	10 Token Code	Four Factor	Re-task temporal surveillance assets Override temporal lockouts due to causality violations Declare a state of temporal emergency Recall all temporal assets Override all command protocols Override of Level 7 access lockouts Place level 8 access lockouts

In this case, a token is defined as a word from the Phonetic Alphabet table or a number.
