Designing & Operating a Multilevel Security Network Using Standard Commercial Products

In March 1996, the 2nd Bomb Wing, Barksdale AFB, LA declared initial operational capability on the first multilevel security system (a.k.a. multilevel network or MLN) using only low-cost commercially available products. The MLN integrates the many sources and sensitivities of information (secret and unclassified) necessary for a commander to effectively command and control global bombing operations. We developed and implemented the MLN for two reasons: • First, to reduce the number of terminals each command and control center (C) operator must use. Multiple non-integrated systems and the technical necessity of separating classified and unclassified systems have created enormous system overhead and operator training inefficiencies base and Air Force wide. In many operational areas, real estate is at a premium and reducing required floor or table space would also improve the work environment. Reducing the number of garrison terminals needed could eventually affect deployed operations, where less combat support weight means more combat weight could be transported. • Second, to reduce operational costs. Costs are reduced by buying commercial products. Savings are enhanced by the commonality of parts among various operational systems as they connect to the network. Training costs will decrease as new operational systems are added to the network because a common human-computer interface would exist between systems. The MLN is working and the single most expensive item is the operating system at roughly $3,000 each ($1900 each with a site license). The MLN is already a model for other C centers and continuous refinement will only improve its desirability.
