6 Architectural Information

The Belkin® OmniView™ Secure KVM Switch architecture is divided into the following

sections in the ST:

Data Separation

Switch Management

The TOE itself is not concerned with the User’s information flowing between the shared

peripherals and the switched computers. It is only providing a connection between the human

interface devices and a selected computer at any given instant.

6.1.1 Data Separation

The Data Separation security function assures that the TOE is connected to only a single

computer at one time. Manual switches allow the operator to select which computer is connected

to the Peripheral Port Group at any given time. Each connected computer has a discrete switch

and hub on the TOE assigned to its USB and each switched computer has its own logical ID

within the TOE through this switch arrangement. Through this dedicated switching mechanism,

the connection between the peripheral port group and the selected computer is activated. The

design of these switches and associated circuitry assure that only a single computer can be

engaged by the keyboard, mouse, and video monitor resources. Through this data separation

security function, the TOE precludes the sharing or transfer of data between computers by the

TOE.

6.1.2 Switch Management

The TOE provides a LED indicator light above the push button switch that indicates to the User

which computer is activated to the peripheral port group. The switch management security

function also supports the switching rule that specifies that Data can flow to a peripheral port

group only if it was received from the same switched computer. The switching mechanism used

is strictly manual and precludes activating two switched computer members at once or partial

activation of more than a single peripheral port group member. The TOE supports domain

separation through the switch management security function and ensures that TSP functions are

successful prior to allowing data to travel through the TOE from the peripheral port group to the

switch computer resource.

6.2 TOE Boundaries

Figure 1 illustrates the Belkin® OmniView™ Secure KVM Switch and its intended

environment. Components other than the Belkin® OmniView™ Secure KVM Switch product

(i.e., Switched Peripheral Port Group and Host Computers), are not part of the TOE.
