Control room with several networks

Shared peripherals are the channel between the domains, and an ordinary KVM switch shares EDID, USB state and sometimes memory.

The problem

What makes it hard

An operator has to see a situational picture on an open network, an agency-internal network and a network handling classified information — at the same time, under time pressure, without the networks ever touching, and without three sets of keyboards on the desk.

Domain switching by key combination rather than by a physical control, and the operator loses track of which domain is active. The active-domain indication sits in the wrong place in the field of view.

How it is built

Shared workstation with physical KVM switching

Four properties separate a secure KVM from an ordinary one: EDID emulation, one-way HID, no shared buffer, tamper indication.
