4 & 8 port Secure KM Switch User Manual

Introduction

Thank you for purchasing this HSL Secure KM Switch. This KM Switch

is designed for use in secure defense and intelligence environments

across wide security gaps. This 3rd Generation Secure KM 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 KM. This 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 product, in addition to troubleshooting guidance—

in the unlikely event of a problem.

What is KM?

There are many cases where one computer user needs to work

simultaneously with few computers. In some cases users are having

multiple displays attached to these multiple computers. The

challenge is how a single user can interact with multiple computers

having multiple displays. KMs would not do a good job for these users

as they were designed to switch displays as well.

KM switch is a device that switches a single set of keyboard and

mouse between multiple computers. KM switch is essentially a KM

switch without the video switching - all displays are continuously

connected to their respective computers.

Package Contents

Inside product packaging you will find the following:

HSL Secure KM Switch unit

12V 1.5 A wall-mounted power Supply (K304x models) or

AC power cable (K308 model)

Important: This product is equipped with always-on active

anti-tampering system. Any attempt to open the product

enclosure will activate the anti-tamper triggers and render the

unit inoperable.

If the unit’s enclosure appears disrupted or if all the channel-

select LEDs flash continuously, please remove product from

service immediately and contact HSL Technical Support.

Security Features

HSL Secure KM Switch is the most advanced and secure commercially

available KM 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 KM.

No Shared Resources

This KM Switch designed to securely operate even when peripheral

devices are vulnerable to signaling attacks. This KM 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 KM control logic.

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 KM 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 KM 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.

Dedicated Peripheral Port (K304E)

HSL patented Dedicated Peripheral Ports enables secure use of CAC

or smart-card readers leveraging security.

Common Criteria Listing

The Switch is listed by the Common Criteria organization.

Operational Features

The HSL Secure KM Switch was designed with the user in mind for

today’s IT environment. Below is a summary of some of the features

incorporated into the Product.

Virtual Display Technology (VDT)

VDT allows the KM to switch automatically between computers once

mouse cursor crosses display borders. Seamless switching between

multiple computers with cusrsor movement.

Support for multiple head

Product can be easily configured to support dual, triple and up to 16

head computers through signed software driver. Note that single

head installation does not need any software installation.

Extensive administrator setup options

Administrator mode provides many customized settings from display

arrangement, size to cursor speed and acceleration.

Dedicate Peripheral Port (K304E only)

HSL K304E Secure KM Switch products supports parallel switching of

wide set of user authentication devices including CAC, smart-card

and biometric readers.

Audio Support

The KM Switch support audio out switching. Microphone switching

not supported to prevent analog leakages through audio ports.

KM Extenders Support

HSL Secure KM Switch supports most copper and fiber KM extenders

connected to the console port.

What is Virtual Display Technology (VDT)?

Virtual Display Technology (VDT) is implemented in HSL Secure KM

switches series to enable seamless cursor and keyboard switching

between multiple displays. VDT allows administrators to configure

any desired displays configuration with same or different size and

resolution. User simply moves mouse cursor across neighboring

displays to switch between connected computers.

Refer to the example in the figure at the right side. Assume that

computer #1 is connected to the left display, computer #2 is

connected to the top display, computer #3 is connected to the center

bottom display and computer #4 is connected to the display at the

right side. In this example all four displays are identical. VDT allows

the user to move the mouse cursor across the four displays while

automatically switch the shared peripherals based on the current

cusrsor location. For example when the user moves the cursor from

the left display to the center bottom display, the KM identifies the

display boarder crossing between these two displays and switches

the KM to computer #3.

HSL VDT is now further enhanced with the inclusion of pointing

device drivers to support dual, triple and up to 16 head computers.

With this technology user workstation may be integrated with any

combination of single, dual, triple and quad head computers.

VDT Configurator software enables the user administrator to easily

configure any set of display sizes, resolutions, geometry and physical

arrangements.
