4. ASSUMPTIONS

4.1 Physical Security Assumptions

A key environmental assumption is physical security, for it is assumed appropriate

physical security protection will be applied to the TOE hardware commensurate with the

value of the IT assets. Specifically, the TOE is assumed to be located within a facility

providing controlled (i.e., employee-only) access to prevent unauthorized physical access

to internal parts of the TOE.

4.2 Personnel Security Assumptions

It is assumed that an authorized user possesses the necessary privileges to access the

information transferred by the TOE – users are authorized users. It is also assumed that

the TOE is installed and managed in accordance with the manufacturer’s directions. It is

assumed that the authorized user is non-hostile and follows all usage guidance.

4.3 Operational Security Assumptions

It is assumed that the TOE meets the appropriate national requirements (in the country

where used) for conducted/radiated electromagnetic emissions. [In the United States Part

15 of the FCC Rules for Class B digital devices]. It is also assumed that only the selected

computer’s video channel will be visible on the shared monitor. It is assumed that

vulnerabilities associated with the attached devices (shared peripherals or switched

computers), or their connection to the TOE, are a concern of the application scenario and

not of the TOE.

4.4 Threats Countered and Not Countered

The TOE is designed to fully or partially counter the following threats:

T.BYPASS

The TOE may be bypassed, circumventing nominal SWITCH functionality

T.INSTALL

The TOE may be delivered and installed in a manner which violates the

security policy.

T.LOGICAL

The functionality of the TOE may be changed by reprogramming in such a

way as to violate the security policy.

T.PHYSICAL

A physical attack on the TOE may violate the security policy.

T.RESIDUAL

RESIDUAL DATA may be transferred between PERIPHERAL PORT

GROUPS with different IDs.

T.SPOOF

Via intentional or unintentional actions, a USER may think the set of

SHARED PERIPHERALS are CONNECTED to one COMPUTER when in

fact they are connected to a different one.

T.STATE

STATE INFORMATION may be transferred to a PERIPHERAL PORT
