It is periodically confirmed that the above Evaluation Facility meets the requirements on the appropriateness of the management and evaluators for maintaining the quality of evaluation. 7.2 Evaluation Approach The evaluation was conducted in accordance with the assurance requirements in the CC Part 3 required by the Conformance PP using the evaluation methods prescribed in the CEM and the assurance activities of the Conformance PP. Details for evaluation activities were reported in the Evaluation Technical Report. The Evaluation Technical Report explains the summary of the TOE as well as the content of the evaluation and the verdict for each work unit in the CEM and assurance activity of the Conformance PP. 7.3 Overview of Evaluation Activity The history of the evaluation conducted is described in the Evaluation Technical Report as follows. The evaluation started in 2023-05 and concluded upon completion of the Evaluation Technical Report dated 2024-01. The Evaluation Facility received a full set of evaluation deliverables necessary for evaluation provided by the developer, and examined the evidence in relation to a series of evaluation conducted. Furthermore, the evaluator conducted the evaluator testing at the developer site in 2023-08 and 09. Concerns in the evaluation process that the Certification Body found were described as the certification oversight reviews and sent to the Evaluation Facility. After the Evaluation Facility and the developer examined the concerns, those were reflected in the Evaluation Technical Report. JISEC-CC-CRP-C0808-01-2024 16 7.4 IT Product Testing As the verification results of the evidence presented in the evaluation process, the evaluator performed the evaluator independent testing to ensure that the security functions of the product are accurately implemented and the evaluator penetration testing based on the vulnerability assessment. 7.4.1 Developer Testing The developer testing is not included in the assurance requirements of this evaluation. 7.4.2 Evaluator Independent Testing The evaluator conducted evaluator independent testing (hereinafter referred to as "independent testing") based on the evidence presented during the evaluation to ensure that the security functions of the product are accurately implemented. The independent testing performed by the evaluator is explained as follows. 1) Independent Testing Environment The environment for the independent testing is based on the operational environment of the TOE shown in Figure 4-1. The components used in the independent testing environment are listed in Table 7-1. Table 7-1 Components of Independent Testing Components Description TOE - SHARP BP-B550WD fax-standard model with BP-FR12U Version: 0110M300 - SHARP BP-B537WR fax-standard model with BP-FR12U Version: 0110M300 Audit server rsyslog ver.8.24.0 Mail server Postfix ver.2.10.1 FTP server Microsoft Internet Information Services ver.10.0.19041.2130 Authentication server openLDAP ver.2.4.44 Client PC OS : Windows 10 Web browser : Microsoft Edge 116 Printer Driver: - SHARP BP-B550WD PCL6 04.00.08.17 - SHARP BP-B537WR PCL6 04.00.08.17 There are following differences between the configuration of the independent testing and the TOE configuration identified in the ST. The evaluator determined that there are no problems with those differences and that the security functions of the TOE configuration identified in the ST can be considered properly tested. JISEC-CC-CRP-C0808-01-2024 17 (1) Tested models In the models of the TOE described in Chapter 2 "TOE identification," there are multiple models due to the following differences: - Difference in printing speed The evaluator determined that the security functions of all the models of the TOE can be considered to have been tested by testing the representative two models considering the above differences, because the security functions of each models are the same. (2) Using a modified firmware for testing In the independent testing, a firmware modified for testing was used to verify the encryption functions instead of the firmware of the TOE. The evaluator determined that the testing on the modified firmware is valid because its modules of the encryption functions are the same as that of the TOE, and the modification for testing does not affect the encryption functions. (3) Using additional testing tools In the independent testing, some testing tools were used to confirm and alter the communication data and to confirm the encryption functions. The validity of those testing tools was confirmed by the evaluator. 2) Summary of the Independent Testing A summary of the independent testing is as follows. a. Viewpoints of the Independent Testing The viewpoints of the independent testing devised by the evaluator based on the requirements of the Conformance PP and on the evaluation documentation submitted for evaluation are shown below. 1. Confirm security functions for each Security Functional Requirement (SFR). 2. Confirm that the implementation of the cryptographic algorithms is correct. b. Independent Testing Outline An outline of the independent testing that the evaluator performed is as follows. The behavior of the TOE for inputs using the control panel of the TOE, the client PC and the testing tools was confirmed by following means: - If the behavior can be confirmed from the external interfaces of the TOE, the external interfaces of the TOE are used. - If the behavior cannot be confirmed from the external interfaces of the TOE, the firmware for testing is used. JISEC-CC-CRP-C0808-01-2024 18 The independent testing was performed on 35 items by the evaluator. Table 7-2 shows contents of the independent testing corresponding to the viewpoints. Table 7-2 Content of the Performed Independent Testing Viewpoint Outline of the Independent Testing 1 Confirmation of security functions Confirm that all security functions work as the specification with the test items created based on the assurance activities of the Conformance PP for each SFR or the requirements of the SFR. 2 Confirmation of implementation of cryptographic algorithms Confirm the following cryptographic algorithms are implemented as the specification using the test program installed in the TOE. - RSA (key generation, signature generation/verification) - ECDSA (signature verification) - AES-ECB-128, AES-ECB-256, AES-CBC-128, AES-CBC-256, AES- GCM-128, AES-GCM-256 - SHA-1, SHA-256, SHA-384, SHA-512 - HMAC-SHA-1, HMAC-SHA-256, HMAC-SHA-384 - CTR_DRBG c. Result All the independent testing performed by the evaluator was correctly completed, and the evaluator confirmed the behavior of the TOE. The evaluator confirmed consistencies between the expected behavior and all the testing results. 7.4.3 Evaluator Penetration Testing The evaluator devised and performed the evaluator penetration testing (hereinafter referred to as the "penetration testing") on the potentially exploitable vulnerabilities of concern under the assumed environment of use and attack level from the evidence presented in the process of the evaluation. The penetration testing performed by the evaluator is explained as follows. (1) Summary of the Penetration Testing A summary of the penetration testing performed by the evaluator is as follows. a.
