4 Executive Summary
4.1 Introduction
This Certification Report states the outcome of the Common Criteria security
evaluation of Thinklogical VX640 Router KVM Matrix Switch to the Sponsor,
Thinklogical, and is intended to assist prospective consumers when judging the
suitability of the IT security of the product for their particular requirements.
Prospective consumers are advised to read this report in conjunction with the
Security Target[1] which specifies the functional, environmental and assurance
evaluation requirements.
4.2 Evaluated Product
The product evaluated was Thinklogical VX640 Router KVM Matrix Switch (VXR-
000640 Rev B)
And Data Input/Output cards:
 Velocity Matrix Router 640 Data Input/Output Card, 20 Ports, SFP+, Multi
Mode (VXM-DIOR20 Rev A),
This product is also described in this report as the Target of Evaluation (TOE). The
developer was Thinklogical.
Details of the evaluated configuration, including the TOE’s supporting guidance
documentation, are given in Annex A.
4.3 TOE scope
4.3.1 System type and overview
The TOE is a 640 x 640 routing system, which provides connection of 640 optical
inputs located on the upper and lower card cage ports to any or all of the 640
optical outputs located on the same upper and lower card cage ports. The TOE
consists of 32 Data Input and Output Cards having 20 optical input and output ports.
The 32 Data Input and Output Cards installed in the upper and lower card cages can
be used to connect any of the 640 Inputs in one direction to any output or multiple
outputs. Any combination of Transmitter Port L1 to Receiver Port L1 or Receiver Port
L2 to Transmitter Port L2. Each of the 32 Data Input and Output Cards connects to
each of the eight 160x160 switch cards through five connections on a passive
backplane. The TOE allows for remote operation of shared computers using sets of
shared peripherals, dynamically connecting (switching) physical ports on a particular
computer to a particular shared peripheral set.
The TOE consists of the following hardware devices:
1. Thinklogical KVM Matrix Switch (VX640 Router)
2. 32 Data Input/Output Cards
Thinklogical VX640 Router KVM Matrix Switch EAL 4
SERTIT-051 CR Issue 1.0
28 November 2013
Page 9 of 20
Velocity Transmitter Extenders are connected to the input ports of the Data Input
and Output Cards located in the upper card cage and to the output ports of the Data
Input and Output cards located in the lower card cage of the Switch using optical
fibers connections.
Velocity Receiver Extenders are connected to the output ports of the Data Input and
Output Cards located in the upper card cage and to the input ports of the Data Input
and Output cards located in the lower card cage of the Switch using optical fibers
connections.
Each Transmitter and Receiver Port Group is composed of two ports: T port and R
port. Two optical cables are then required to connect a Velocity Transmitter or
Receiver Extender to a Transmitter or Receiver Port Group on the Switch. One cable is
used to transmit data from the Extender to the Switch; the other cable is used to
transmit data from the Switch to the Extender. As a result, a bi-directional
connection is established, where data can flow in both directions.
All data types, including video, audio and serial data are converted to an optical
form and transmitted in a single optical cable.
The purpose of the Switch is to establish logical connections between Transmitter
and Receiver Port Groups, while preserving Data Separation Security Function Policy
(SFP).
Data Separation Security Function Policy (SFP) states that data shall flow between
Transmitter Port A and Receiver Port B if and only if a deliberate logical connection
has been established to connect A to B. There shall be no other data flow between a
Transmitter Port or a Receiver Port and any other physical port on the Switch.
The use of a restrict or partition table in the system overrides any deliberate logical
connection established between Transmitter Port A and Receiver Port B since the
restrict policy disallows connection of a higher priority input to a lower priority
output and the partition policy disallows connection of an input from one partition
going to the output of another partition.
The TOE connections are first controlled by restrict and priority tables and then
controlled, if not in conflict with the restrict or partition tables, over the serial RS-
232/console interface, a wired 10/100BASE-TX LAN connection.
4.3.2 Physical boundaries
VX 640 Router KVM Matrix Switch is a hardware device. TOE Physical Boundaries then
correspond to the physical boundaries of the device enclosure.
4.3.3 Logical boundaries
TOE logical boundaries include all software and firmware components inside the VX
640 Router KVM Matrix Switch.
The following Security Functions are provided by the TOE
Thinklogical VX640 Router KVM Matrix Switch EAL 4

these objectives meet and security functional requirements and security functions to
elaborate the objectives. All of the SFR’s are taken from CC Part 2[3]; use of this
standard facilitates comparison with other evaluated products.
4.8 Threats Countered
 Residual data may be transferred between different port groups in violation of
data separation security policy.
 State information may be transferred to a port group other than the intended
one.
4.9 Threats Countered by the TOE’s environment

Switch to the transmitters and receivers and the wired network connections
from the TOE to the administrators shall be physically secure.
 Vulnerabilities associated with attached devices or their connections to the
TOE, shall be a concern of the application scenario and not of the TOE.
4.14 Security Functional Requirements
 FDP_ETC.1.1 Enforce the Data Separation Policy when exporting user data,
controlled under the SFP, from outside of the TOE.
 FDP_ETC.1.2 Export the user data without the user data's associated security
attributes.
 FDP_IFC.1.1 Enforce the Data Separation Policy on the set of Transmitter and
Receiver Port Groups, and the bi-directional flow of data and state
information between the shared peripherals and the switched computers.
 FDP_IFF.1.1 Enforce the Data Separation Policy based on the following types
of subject and information security attributes:
- Transmitter and Receiver Port Groups (subjects)
- peripheral data and state information (objects)

 FDP_IFF.1.2 Permit an information flow between a controlled subject and
controlled information via a controlled operation if the following rules hold:
Thinklogical VX640 Router KVM Matrix Switch EAL 4
Page 12 of 20 SERTIT-051 CR Issue 1.0
28 November 2013
- peripheral data and state information can only flow between
Transmitter and Receiver port groups that have been previously
logically connected by the administrator using the TOE management
interface
 FDP_IFF.1.3 Enforce that Transmitter Port Group may be logically connected
to multiple Receiver Port Groups, out of which bi-directional information flow
will be established only with a single Primary Receiver Port Group selected by
the administrator. The remaining Non-Primary Receiver port groups will only
receive unidirectional multicast audio and video signals. Any Receiver Port
Group may only be logically connected to a single Transmitter Port Group.
 FDP_IFF.1.5 Explicitly deny an information flow based on the following rules:
- No data or state information flow shall be allowed between logically
unconnected port groups.
- No data or state information flow shall be allowed between any two

4.15 Security Function Policy
The TOE logically connects Transmitter and Receiver Port Groups according to the
current switching configuration. The data flows between a particular Transmitter Port
Group and a set of Receiver Port Groups if and only if there is an active logical
connection connecting these. If there are multiple Receiver Port Groups connected to
a Transmitter Port Group, bi-directional information flow will be then established
between the Primary Receiver Port Group and the Transmitter Port Group. The
remaining Non-Primary Receiver Port Groups will receive uni-directional multi-cast
video and audio signals from the Transmitter Port Group.
4.16 Evaluation Conduct
The evaluation was carried out in accordance with the requirements of the
Norwegian Certification Scheme for IT Security as described in SERTIT Document
SD001E[5]. The Scheme is managed by the Norwegian Certification Authority for IT
Security (SERTIT). As stated on page 2 of this Certification Report, SERTIT is a
member of the Arrangement on the Recognition of Common Criteria Certificates in
the Field of Information Technology Security (CCRA), and the evaluation was
conducted in accordance with the terms of this Arrangement.
Thinklogical VX640 Router KVM Matrix Switch EAL 4
SERTIT-051 CR Issue 1.0

Page 13 of 20
The purpose of the evaluation was to provide assurance about the effectiveness of
the TOE in meeting its Security Target[1], which prospective consumers are advised to
read. To ensure that the Security Target[1] gave an appropriate baseline for a CC
evaluation, it was first itself evaluated. The TOE was then evaluated against this
baseline. Both parts of the evaluation were performed in accordance with CC Part
3[4] and the Common Evaluation Methodology (CEM)[6].
SERTIT monitored the evaluation which was carried out by the Norconsult AS
Commercial Evaluation Facility (CLEF/EVIT). The evaluation was completed when the
EVIT submitted the Evaluation Technical Report (ETR)[7] to SERTIT on 28.11.2013.
SERTIT then produced this Certification Report.
4.17 General Points
The evaluation addressed the security functionality claimed in the Security Target[1]
with reference to the assumed operating environment specified by the Security
Target[1]. The evaluated configuration was that specified in Annex A. Prospective
consumers are advised to check that this matches their identified requirements and
give due consideration to the recommendations and caveats of this report.
Certification does not guarantee that the IT product is free from security
vulnerabilities. This Certification Report and the belonging Certificate only reflect
the view of SERTIT at the time of certification. It is furthermore the responsibility of
users (both existing and prospective) to check whether any security vulnerabilities
have been discovered since the date shown in this report. This Certification Report is
not an endorsement of the IT product by SERTIT or any other organization that
recognizes or gives effect to this Certification Report, and no warranty of the IT

5.1 Introduction
The evaluation addressed the requirements specified in the Security Target[1]. The
results of this work were reported in the ETR[7] under the CC Part 3[4] headings. The
following sections note considerations that are of particular relevance to either
consumers or those involved with subsequent assurance maintenance and re-
evaluation of the TOE.
5.2 Delivery
On receipt of the TOE, the consumer is recommended to check that the evaluated
version has been supplied, and to check that the security of the TOE has not been
compromised in delivery.
Thinklogical’s delivery procedure [8] describes how the TOE is shipped from
Thinklogical’s warehouse via Federal Express, UPS or DHL to the customer. The
procedure explains that all tracking and shipment information are logged, and upon
delivery of the TOE a signature is required. Each shipment is noted with dimension
and weight, and hard copies of each shipment are held in Thinklogical’s Sales Order
folder.
The product manual [9] describes that users has to verify and ensure that all parts of
the TOE has been delivered in the correct version. The text states that if the user has
ordered an EAL4 certified unit, the user has to verify that he or she has received the
proper materials.
5.3 Installation and Guidance Documentation
A description of the secure installation of the TOE and the secure preparation of the
operational environment in accordance with the security objectives in the ST [1] can
be found in the product manual [9].
The guidance documentation [9] describes the security functionality and interfaces
provided by the TSF, it provides instructions and guidelines for the secure use of the
TOE, it addresses secure procedures for all modes of operation, facilitates prevention
and detection of insecure TOE states.
A list of all guidance documents evaluated can be found in Annex A.
5.4 Misuse
There is always a risk of intentional and unintentional misconfigurations that could
possibly compromise confidential information. Administrators should follow the
guidance for the TOE in order to ensure that the TOE operates in a secure manner.
The guidance document adequately describes the mode of operation of the TOE, all
assumptions about the intended environment and all requirements for external
security. Sufficient guidance is provided for the consumer to effectively administer
and use the TOE’s security functions

28 November 2013
5.5 Vulnerability Analysis
The evaluators’ assessment of potential exploitable vulnerabilities in the TOE has
been addressed and shows that the vulnerability analysis is complete, and that the
TOE in its intended environment is resistant to attackers with an Enhanced-Basic
attack potential.
5.6 Developer’s Tests
The evaluators’ assessments of the developers’ tests shows that the developer testing
requirements is extensive and that the TSF satisfies the TOE security functional
requirements. The testing performed on the TOE by both the developer and evaluator
showed that the EAL 4 assurance components requirements are fulfilled.
5.7 Evaluators’ Tests
The evaluator have independently tested the TSFs and verified that the TOE behaves
as specified in the design documentation and confidence in the developer's test
results is gained by performing a sample of the developer's tests.

Environmental Configuration
The TOE is a hardware device. The TOE provides remote connections from a set of
shared computers to a set of shared peripherals. The switching capability of the TOE
is used to connect ports on a particular computer to a particular peripheral set. The
corresponding electronic signal from a computer port is transformed into an optical
signal by the Velocity extender, transmitted through an optical fiber, switched by the
KVM Matrix Switch to another optical fiber, and then transformed back to an
electronic form by the Velocity extender. The resulting signal is used by the shared
peripherals.
