Wang modifies KVM switch for Tempest, Zone specs

Wang Government Services Inc. of McLean, Va., is adding a keyboard, video and mouse switch to its line of computer equipment designed to prevent electronic eavesdropping.

Wang will modify Desktop KVM switches from Raritan Computer Inc. of Somerset, N.J., to meet National Security Agency Tempest and Zone restrictions on electronic emanations.

The switches let a user access up to four CPUs from one keyboard, monitor and mouse.

Tempest is an acronym for transient electromagnetic pulse emulation standard. Tempest-approved products are shielded and re-engineered to prevent eavesdropping on the electronic signals that bleed from unshielded computer equipment.

Undetectable spying

Zone specifications are specific to individual users' needs and usually consist of a subset of the full Tempest specs.

Electronic eavesdropping 'is one of the worst attacks we can face' because it cannot be detected, said Chris Wahlen, Wang vice president for secure systems.

Wang's Tempest products include PCs, servers, LAN equipment and printers. The market for such secure products is entirely in the federal classified community, Wahlen said, and 'there has been absolutely no embracing on the commercial side.'

KVM equipment fills a need for classified systems users who must segregate information of differing classifications.

Wang will modify off-the-shelf Raritan switches to meet NSA specifications and price them according to the specification set.

Products are available on the Defense Department's Systems Acquisition and Support Services Hardware II contract.

Contact Wang at 703-827-3000.
