Under this NSCIB, TrustCB B.V. has the task of issuing certificates for IT security products, as well as for protection profiles and sites. Part of the procedure is the technical examination (evaluation) of the product, protection profile or site according to the Common Criteria assessment guidelines published by the NSCIB. Evaluations are performed by an IT Security Evaluation Facility (ITSEF) under the oversight of the NSCIB Certification Body, which is operated by TrustCB B.V. in cooperation with the Ministry of the Interior and Kingdom Relations. An ITSEF in the Netherlands is a commercial facility that has been licensed by TrustCB B.V. to perform Common Criteria evaluations; a significant requirement for such a licence is accreditation to the requirements of ISO Standard 17025 ' General requirements for the accreditation of calibration and testing laboratories ' . By awarding a Common Criteria certificate, TrustCB B.V. asserts that the product or site complies with the security requirements specified in the associated (site) security target, or that the protection profile (PP) complies with the requirements for PP evaluation specified in the Common Criteria for Information Security Evaluation. A (site) security target is a requirements specification document that defines the scope of the evaluation activities. The consumer should review the (site) security target or protection profile, in addition to this certification report, to gain an understanding of any assumptions made during the evaluation, the IT product's intended environment, its security requirements, and the level of confidence (i.e., the evaluation assurance level) that the product or site satisfies the security requirements stated in the (site) security target.

Page: 7/12 of report number: NSCIB-CC-2400066-01-CR, dated 29 January 2026 ####### · Security Management The TSF shall enforce security attributes through identification and authentication of administrators and operators before giving any administrative access to the TOE (i.e., giving any access to TSF management functions. The TSF management functions allow for the changes of logical TOE connection via the Restrict, Partition, and P2P Tables. ####### · Protection of the TSF The TOE runs a suite of self-tests during initial startup and or after activating the reset button. The self-test includes a test of the basic TOE hardware and firmware integrity. ####### · Identification and Authentication The TOE maintains a single administrator role and operator role with the 'Timing of identification' SFR which ensures that only an operator or administrator can identify themselves to the TOE. ## 2.3 Assumptions and Clarification of Scope ### 2.3.1 Assumptions The assumptions defined in the Security Target are not covered by the TOE itself. These aspects lead to specific Security Objectives to be fulfilled by the TOE-Environment. For detailed information on the security objectives that must be fulfilled by the TOE environment, see section 4.2 of the [ST] . ### 2.3.2 Clarification of scope The evaluation did not reveal any threats to the TOE that are not countered by the evaluated security functions of the product. ## 2.4 Architectural Information The TOE architecture can be depicted as follows: ## 2.5 Documentation The following documentation is provided with the product by the developer to the customer: ® TrustCB is a registered trademark.

All parameter choices were addressed at least once. All boundary cases identified were tested explicitly, and additionally the near-boundary conditions were covered probabilistically. The testing was largely automated using industry standard and proprietary test suites. Test scripts were used extensively to verify that the functions return the expected values. The evaluators reproduced a selection of the developer tests, as well as a small number of test cases designed by the evaluator. ### 2.6.2 Independent penetration testing Because the TOE is located in a physically protected environment where only trusted authorized administrator can access it and make any change (physical and logical) to it. The system user has very limited interaction with the TOE (switch the ports based on the restrictions, send hot key to make pre-defined connection, send key/mouse signal passing the TOE to the source, receive response from the source). Therefore, there is very limited attack surface and attack path to the TOE. Due to the very limited attack path, the vulnerability analysis is performed in only three parts - SFR Design Analysis: Based on the information obtained in the evaluation evidence, the SFR implementation details were examined. The aspects described in CEM annex B were considered. During this examination several potential vulnerabilities were identified. - CWE Vulnerability focus: When the implementation of the SFR was understood, a coverage check were performed on the relevant aspects of all SFRs. This expanded the list of potential vulnerabilities. - Public domain analysis: The evaluator performed public domain vulnerability search based on the TOE name, TOE type, and identified 3rd party security relevant libraries and/or services. Several additional potential vulnerabilities were identified during a search in the public domain. - User mistakes: Considering that no external threat can reach the TOE and the internal users are trusted according to the OE, the only thing that remains are user mistakes. Potential vulnerabilities were identified during a search in this domain. The potential vulnerabilities identified were analyzed, and some of the potential vulnerabilities were concluded not exploitable within in the Enhanced-Basic attack potential, or covered by guidance. For remaining potential vulnerabilities, penetration tests were devised. ® TrustCB is a registered trademark. Any use or application requires prior approval. Page: 9/12 of report number: NSCIB-CC-2400066-01-CR, dated 29 January 2026 The total test effort expended by the evaluators was 70 hours. During that test campaign, 100% of the total time was spent on logical tests. ### 2.6.3 Test configuration The TOE was tested in the following configuration: - TLX Matrix Switch Chassis TLX-MSC-000160 Rev B quantity 1 - TLX Matrix Switch Controller Card TLX-MSM-C000160 Rev B, quantity 2 - CONTROLLER CARD, PCB 000525-R REV A, ASSY XGXA-000020 - TLX Matrix Switch Data I/O Card TLX-MSD-M00010 Rev A, quantity 16 - 10 PORT FIBER I/O CARD, PCB 000527-R Rev A, ASSY XGXA-000022 - IMX6 PROCESSOR CARD, PCB 000458 - R REV C, ASSY DCSA-000081 - FAN TRAY, PCB 000529-R REV B, ASSY XGXA-000024 - BACKPLANE, PCB 000524-R REV B, ASSY XGXL-000019 ### 2.6.4 Test results The testing activities, including configurations, procedures, test cases, expected results and observed results are summarised in the [ETR] , with references to the documents containing the full details. The developer's tests and the independent functional tests produced the expected results, giving assurance that the TOE behaves as specified in its [ST] and functional specification. No exploitable vulnerabilities were found with the independent penetration tests. ## 2.7 Reused Evaluation Results There has been extensive reuse of the ALC aspects for the sites involved in the development and production of the TOE, by use of 1 Site Technical Audit Report. No sites have been visited as part of this evaluation. ## 2.8 Evaluated Configuration The TOE is defined uniquely by its name and version number Thinklogical TLX160 Matrix Switch Chassis (TLX-MSC-000160) Rev. B. ## 2.9 Evaluation Results The evaluation lab documented their evaluation results in the [ETR] , which references an ASE Intermediate Report and other evaluator documents. The verdict of each claimed assurance requirement is ' Pass '. Based on the above evaluation results the evaluation lab concluded the Thinklogical TLX160 Matrix Switch Chassis (TLX-MSC-000160) Rev. B, to be CC Part 2 conformant, CC Part 3 conformant , and to meet the requirements of EAL 4 augmented with ALC_FLR.2 . This implies that the product satisfies the security requirements specified in Security Target [ST] . ## 2.10 Comments/Recommendations The user guidance as outlined in section 2.5 ' Documentation ' contains necessary information about the usage of the TOE. Certain aspects of the TOE's security functionality, in particular the countermeasures against attacks, depend on accurate conformance to the user guidance of both the software and the hardware part of the TOE. There are no particular obligations or recommendations for the user apart from following the user guidance. Please note that the documents contain relevant details concerning the resistance against certain attacks. The user of the TOE must carefully verify the correctness of the Restriction, Partition, and P2P csv tables as mentioned in the TLX160 Product Manual p.43, p47, and p49. The csv tables must be entirely correct, strictly follow the syntax defined for the restriction table, p42, partition table p45, P2P ® TrustCB is a registered trademark. Any use or application requires prior approval. Page: 10/12 of report number: NSCIB-CC-2400066-01-CR, dated 29 January 2026 table p48, and located in the right folder. Any error in the csv table may cause unexpected information flow or unexpected behaviour of the TOE. In addition, all aspects of assumptions, threats and policies as outlined in the Security Target not covered by the TOE itself must be fulfilled by the operational environment of the TOE. The customer or user of the product shall consider the results of the certification within his system risk management process. For the evolution of attack methods and techniques to be covered, the customer should define the period of time until a re-assessment for the TOE is required and thus requested from the sponsor of the certificate.
