The Belkin Secure KVM product uses multiple microcontrollers to emulate the connected
peripherals in order to prevent various methods of attacks such as: display signaling, keyboard
signaling, power signaling etc. The product is also equipped with multiple unidirectional flow
forcing devices to assure adherence to the organizational confidentiality policy and flow
between coupled computers.
The Belkin Secure KVM line products are available in 2, 4, 8 or 16 port models with single or
dual ‐ head (displays). Products include traditional KVM switching devices, desktop controller
unit (DCU), direct display connection products (KM), Windowing KVM to allow secure
interaction with multiple connected computers.
The Belkin Secure KVM works with standard Personal Computers running operating systems
such as Windows or Linux and have ports for USB keyboard, USB mouse, DVI ‐ I video, DVI ‐ D
video, audio (input and output), and USB Common Access Card (CAC) or Smart ‐ Card reader.
The TOE is intended to be used in a range of security settings (i.e. computers coupled to a single
TOE can vary from non ‐ classified Internet connected to those protected in accordance with
national security policy). Any data leakage across the TOE may cause severe damage to the
organization and therefore must be prevented.
Unlike older Secure KVM security schemes that mostly protected user information transitioning
through the TOE, the modern approach primarily addresses the risk of TOE compromise
through remote attacks to coupled networks which could leak local user information.
A summary of the Belkin Secure KVM security features can be found in Section 1.4. A detailed
description of the TOE security features can be found in Section 6, TOE Summary Specification.
