Contract Number: MDA904-02-D-0612
Contract Expiration Date: September 30, 2004

Contract Description: The Defense Information Infrastructure (DII) Guard is the system component used to support the DMS requirement to support the exchange of electronic messages between security enclaves. Developed under the National Security Agency's Multilevel Information Systems Security Initiative (MISSI), the DII Guard ensures compliance with the Joint Staff's Secret and Below Interoperability (SABI) approach for messaging.

The DII Guard is comprised of four primary components: The X.400/SMTP Message Transfer Agent (MTA), the Message Guard, the X.500 Directory Server Agent (DSA), and the X.500 Directory Guard. In addition, it has three DII Guard utility programs. The DII Guard operates on the Pentium based DigitalNet XTS-300tm platform, a Class B3 Trusted Computer System. The platform uses the Secure Trusted Operating Program (STOP) V5.2EU3 (or higher) as its operating system. The DigitalNet XTS-300tm and the STOP operating system are collectively referred to as the DII High Assurance Guard.

The DII Guard implementation allows users to send and receive electronic mail messages. The data sensitivities expected to be processed by the DII Guard up to the Secret level. The DII Guard will allow the bi-directional flow of unclassified X.400 and SMTP messages. By policy, the X.500 directory shadowing is allowed to flow only from low to high.

The DII Guard comes in two system types: a prime system, or one that has a license to use the DII Guard application software and STOP operating system, and a spare system, or one that does not include a license to use the DII Guard application software or STOP operating system. However, a spare system may temporarily execute the software in the event of the mal-function of the prime systems hardware, or if the prime system is taken off-line for preventive maintenance. Both the prime and spare systems can be ordered in one of four hardware configurations: a tower unit, a 6U rack-mount unit, a 2U rack-mount unit, and a ruggedized 2U rack-mount unit.

The STOP Operating System and related software and documentation are subject to the International Traffic in Arms Regulations (ITAR) and may require a U.S. State Department license. Therefore an order requiring OCONUS (with the exception of Alaska and Hawaii) shipment may also require the receipt of an export license approval from the U.S. Department of State.
