K244E Secure Dual-Head KVM Switch User Manual

Introduction

Thank you for purchasing this HSL Secure Dual-head DVI-I KVM

Switch. This KVM Switch is designed for use in secure defense and

intelligence environments across wide security gaps. This 3rd

Generation Secure KVM Switch offers optical data diode per channel.

Optical data diodes are used to prevent data transfer between

connected computers running at different security levels even if

these computers attempts to attack the KVM. HSL K244 Secure KVM

switch product provides the highest security safeguards and features

that meet today’s and will meet future cyber prevention

requirements.

This User Manual provides all the details you’ll need to install and

operate your new Switch, in addition to troubleshooting guidance—

in the unlikely event of a problem.

Package Contents

Inside product packaging you will find the following:

HSL K244E Secure Dual-Head DVI-I KVM Switch unit

12V 1.5A DC Power Supply

Security Features

HSL Secure KVM Switch is the most advanced and secure

commercially available KVM Switch available today. Below is a

summary of some of the security features incorporated into the

product.

Unidirectional Data Paths

Optical diodes used to enforce unidirectional data flow from the

peripheral devices to computers preventing potential leakage paths

between computers even in the severe threat of two infected

computers attacking the KVM.

No Shared Resources

This KVM Switch designed to securely operate even when peripheral

devices are vulnerable to signaling attacks. This KVM Switch does not

allow computer access to any shared resource and does not share

controllable power sources.

Dedicated Processors for Emulation

The Switch features a dedicated processor per computer port to

emulate peripheral devices. This keeps each computer running on

different security levels physically separated and secure at all times,

and prevents any unintended data leakage between computers.

Non-Reprogrammable Firmware

The Switch features custom firmware that is not reprogrammable,

preventing the ability to remotely attack the KVM control logic.

EDID Emulation and Firewall

HSL Secure KVM Switch blocks the computer access to the shared

display by using isolated EDID emulators. This arrangement together

with the internal EDID firewall protects from KVM attacks targeting

the external memory effect of the shared display.

USB Ports Protection

Console USB ports are protected from the use of storage and other

unsafe USB devices through strong filtering (independent of

computer protection means). Unqualified devices are rejected when

connected to the Switch. Only mouse and keyboard data are passed

through.

Heavy-duty Steel Enclosure

HSL Secure KVM Switches uses thick steel components to protect the

product from physical tampering and to minimize radiated

electromagnetic emissions that can be snooped or intercepted.

Active Always-On Anti-Tamper

Active chassis anti-tamper system prevents the KVM electronic

circuitry from being accessed and tampered with by permanently

disabling the product once tampering is detected.

Holographic Tamper-Evident Labels

Four serially numbered holographic security tamper-evident labels

are placed on the enclosure surface to provide a visual indication if

the Switch has been opened or compromised.
