Here List of EarthForce Secuity Levels for information. I believe this will prove useful for those who want to to EA related campaigns. In is taken from the EarthForce Campaign Book from the B5: RPG
PUBLIC: The information in the Document is not Secret and can be viewed by anyone
NOFORN: The information in the Document is not for the use of Foreign nationals or aliens
EYES ONLY: The information should only be read (off a computer screen), not printed, copied or stored in any fashion.
BRAIN ONLY: Rarely seen outside the upper echelons of the intelligence comunity, Brain Only data is either transmitted by Telepath couriers, or is decoded by pre-existing hypnotic routines - to anyone without the hypnotic comands, the information looks like a random pattern of light and sound. (Garibaldi got at least one of these during S4. Sheridan possibly got one in ACTA)
CONFIDENTIAL: The Document is for the use of EarthForce, EarthGov, and other official government bodies (Such as the Psi Corps) only, and should not be distributed to civilians without a security clearance.
CLASSIFIED: The information is restricted to EarthForce only. Ditributing Classified data is a Level 2 offence.
(L2 offence - minor, worth disciplinary action but not a mark on permanent Record. Punishments include Considerable Extra Duty and/or detention/cofined to quarters)
SECRET: The information is considered a secret by EarthForce; only those with secret clearence can read it. Getting a Secret clearance is relativly easy; all EF officers and most specialists, warrent officers and senior NCOs will have Secret Clearance. Most Technical documents are Secret. Distribuiting this Data is a Level 4 Offence.
(L4 Offence - major; a dereliction of duty. This level of breach will way heavily on the offender's permanent record. Punishment: Docked pay and/or suspension and/or transfer to other duty and/or mark on permanent record)
VERY SECRET - Used for tactical information. Very Secret data includes current enemy troop deploymens, info about EF assignments, info about alien governments obtained by EFI (EarthForce Intelligence) and so on. Commanders and higher will generally have Very Secret clearance.
TOP SECRET - The highest clearance most officers ever know about, let alone possess, Top Secret is used for the most sensitive information. Distributing Top Secret inormation is a Level 7 Offence.
(L7 Offence - Treason; the offende has betrayed EarthForce completely and wilfully. Punishment: Dishonerable discharge and/or imprisionment - Death of Personality (depending on the severity of the treason.))
ULTRA VIOLET (aka Ultra Secret): - Ultra Violet's mere existance is not know to most people in EarthForce; awareness of UV is very much on a need to know basis. It is reserved for various super-secret projects like Project Tarsus and the Advanced Destroyer Program. Distributing UV information is an offence normally punished by the offender disappearing and never being seen by human eyes again.
In addition to the clearences taken from above, there are also 5 channel codes that indicate how a message may be tranmitted.
BRONZE: Any transmission method may be used. Bronze messages can be transmitted in the clear by radio if no other options are available, as Bronze messages are not expected to be secure.
SILVER: The Default transmission level, Silver Channel messages are expected to be transmitted via secure means, using encrypted tachyon broadcasts or uninterceptable point-to-point lasers.
GOLD: Gold Channel messages are the highest level of standard security channel. Messages sent via gold channel are heavily encrypted using the most secure codes. Maintaining the integrety of Gold Channel communications is vital for any military unit as most communications from HeadQuaters come via Gold Channel.
BLACK: For a communication channel to be rated Black, it has to be even more secure than Gold. Only a handful of places have the cryptographic technollogy and computer security necissary to qualify for Black level.
NULL: A message with the Null tag may not be transmitted or relayed in any fashion. Null messages must be delivered by courier, and that courier must be given whatever protection or passage is needed to get the message to its destination
