It describes the evaluation result and its soundness and conformity. The Target of Evaluation (hereinafter referred to as “TOE”) is Electronic Document Encryption designed to protect important documents managed by the organization based on the encryption/decryption. Also, the TOE provides a variety of security features: security audit, the user identification and authentication including mutual authentication between TOE components, security management, the TOE access session management, and the TSF protection function, etc. The evaluation of the TOE has been carried out by Korea System Assurance (KOSYAS) and completed on February 20, 2024. This report grounds on the Evaluation Technical Report[7] had submitted and the Security Target(ST)[4]. The ST claims conformance to the Korean National Protection Profile for Electronic Document Encryption V1.1[3]. All Security Assurance Requirements (SARs) in the ST are based only upon assurance component in CC Part 3, and the TOE satisfies the SARs of Evaluation Assurance Level EAL1+. The ST and the resulting TOE is CC Part 3 conformant. The Security Functional Requirements (SFRs) are based upon both functional components in CC Part 2 and a newly defined component in the Extended Component Definition chapter of the PP, therefor the ST, and the TOE satisfies the SFRs in the ST. Therefore, the ST and the resulting TOE is CC Part 2 extended. [Figure 1] shows the operational environment of the TOE. The TOE is composed of the Document SAFER Blue 3 Server(“Server(TOE)” hereinafter) which manages the security policy and cryptographic key, the Document SAFER Blue 3 Agent(“Agent”(TOE) hereinafter) that performs Electronic Document encryption/decryption installed in the user PC, and the Document SAFER Blue 3 Core(“Core”(TOE) hereinafter) that performs Electronic Document encryption installed in the information system in the form of API module. A wrapper is used for compatibility between the Core and various information systems, but it is outside of the TOE scope.

Each test case includes the following information: ⚫ Test no.: Identifier of each test case ⚫ Test Purpose: Includes the security functions to be tested ⚫ Test Configuration: Details about the test configuration ⚫ Test Procedure detail: Detailed procedures for testing each security function ⚫ Expected result: Result expected from testing ⚫ Actual result: Result obtained by performing testing ⚫ Test result compared to the expected result: Comparison between the expected and actual result The developer correctly performed and documented the tests according to the assurance component ATE_FUN.1. The evaluator has installed the product using the same evaluation configuration and tools as the developer’s test and performed all tests provided by the developer. The evaluator has confirmed that, for all tests, the expected results had been consistent with the actual results. In addition, the evaluator conducted penetration testing based upon test cases devised by the evaluator resulting from the independent search for potential vulnerabilities. The evaluator testing effort, the testing approach, configuration, depth, and results are summarized in the ETR [7]. 8. Evaluated Configuration The TOE is software consisting of the following components: TOE: Document SAFER Blue 3 (3.0.02) Certification Report Page 13 - Document SAFER Blue 3 Server 3.0.02 - Document SAFER Blue 3 Agent 3.0.02 - Document SAFER Blue 3 Core 3.0.02 The Administrator can identify the complete TOE reference after installation using the product’s Info check menu. And the guidance documents listed in this report chapter 6, [Table 5] were evaluated with the TOE 9. Results of the Evaluation The evaluation facility provided the evaluation result in the ETR [7] which references Single Evaluation Reports for each assurance requirement and Observation Reports. The evaluation result was based on the CC [1] and CEM [2]. The TOE was evaluated based on Common Criteria for Information Technology Security Evaluation. (EAL1+). As a result of the evaluation, the verdict PASS is assigned to all assurance components. 9.1 Security Target Evaluation (ASE) The ST Introduction correctly identifies the ST and the TOE, and describes the TOE in a narrative way at three levels of abstraction (TOE reference, TOE overview and TOE description), and these three descriptions are consistent with each other. Therefore, the verdict PASS is assigned to ASE_INT.1. The Conformance Claim properly describes how the ST and the TOE conform to the CC and how the ST conforms to PPs and packages. Therefore, the verdict PASS is assigned to ASE_CCL.1. The Security Objectives for the operational environment are clearly defined. Therefore, the verdict PASS is assigned to ASE_OBJ.1. The Extended Components Definition has been clearly and unambiguously defined, and it is necessary. Therefore, the verdict PASS is assigned to ASE_ECD.1. The Security Requirements is defined clearly and unambiguously, and they are internally consistent. Therefore, the verdict PASS is assigned to ASE_REQ.1. The TOE Summary Specification addresses all SFRs, and it is consistent with other narrative descriptions of the TOE. Therefore, the verdict PASS is assigned to ASE_TSS.1. Certification Report Page 14 Thus, the ST is sound and internally consistent, and suitable to be used as the basis for the TOE evaluation. The verdict PASS is assigned to the assurance class ASE. 9.2 Life Cycle Support Evaluation (ALC) The developer has uniquely identified the TOE. Therefore, the verdict PASS is assigned to ALC_CMC.1. The configuration management document verifies that the configuration list includes the TOE and the evaluation evidence. Therefore, the verdict PASS is assigned to ALC_CMS.1. Also the evaluator confirmed that the correct version of the software is installed in device. The verdict PASS is assigned to the assurance class ALC. 9.3 Guidance Documents Evaluation (AGD) The procedures and steps for the secure preparation of the TOE have been documented and result in a secure configuration. Therefore, the verdict PASS is assigned to AGD_PRE.1. The operational user guidance describes for each user role the security functionality and interfaces provided by the TSF, provides instructions and guidelines for the secure use of the TOE, addresses secure procedures for all modes of operation, facilitates prevention and detection of insecure TOE states, or it is misleading or unreasonable. Therefore, the verdict PASS is assigned to AGD_OPE.1. Thus, the guidance documents are adequately describing the user can handle the TOE in a secure manner. The guidance documents take into account the various types of users (e.g. those who accept, install, administrate or operate the TOE) whose incorrect actions could adversely affect the security of the TOE or of their own data. The verdict PASS is assigned to the assurance class AGD. 9.4 Test Evaluation (ATE) The developer correctly performed and documented the tests in the test documentation. Therefore, the verdict PASS is assigned to ATE_FUN.1. By independently testing a subset of the TSFI, the evaluator confirmed that the TOE Certification Report Page 15 behaves as specified in the functional specification and guidance documentation. Therefore, the verdict PASS is assigned to ATE_IND.1. Thus, the TOE behaves as described in the ST and as specified in the evaluation evidence (described in the ADV class). The verdict PASS is assigned to the assurance class ATE. 9.5 Development Evaluation (ADV) The functional specifications specify a high-level description of the SFR-enforcing and SFR-supporting TSFIs, in terms of descriptions of their parameters. Therefore, the verdict PASS is assigned to ADV_FSP.1. The verdict PASS is assigned to the assurance class ADV. 9.6 Vulnerability Assessment (AVA) By penetrating testing, the evaluator confirmed that there are no exploitable vulnerabilities by attackers possessing basic attack potential in the operational environment of the TOE. Therefore, the verdict PASS is assigned to AVA_VAN.1. Thus, potential vulnerabilities identified, during the evaluation of the development and anticipated operation of the TOE or by other methods (e.g. by flaw hypotheses), don’t allow attackers possessing basic attack potential to violate the SFRs. The verdict PASS is assigned to the assurance class AVA. 9.7 Evaluation Result Summary Assurance Class Assurance Component Evaluator Action Elements Verdict Evaluator Action Elements Assurance Component Assurance Class ASE ASE_INT.1 ASE_INT.1.1E PASS PASS PASS ASE_INT.1.2E PASS ASE_CCL.1 ASE_CCL.1.1E PASS PASS ASE_OBJ.1 ASE_OBJ.1.1E PASS PASS ASE_ECD.1 ASE_ECD.1.1E PASS PASS ASE_ECD.1.2E PASS ASE_REQ.1 ASE_REQ.1.1E PASS PASS Certification Report Page 16 Assurance Class Assurance Component Evaluator Action Elements Verdict Evaluator Action Elements Assurance Component Assurance Class ASE_TSS.1 ASE_TSS.1.1E PASS PASS ASE_TSS.1.2E PASS ALC ALC_CMC.1 ALC_CMC.1.1E PASS PASS PASS ALC_CMS.1 ALC_CMS.1.1E PASS PASS AGD AGD_PRE.1 AGD_PRE.1.1E PASS PASS PASS AGD_PRE.1.2E PASS AGD_OPE.1 AGD_OPE.1.1E PASS PASS ADV ADV_FSP.1 ADV_FSP.1.1E PASS PASS PASS ADV_FSP.1.2E PASS ATE ATE_FUN.1 ATE_FUN.1.1E PASS PASS PASS ATE_IND.1 ATE_IND.1.1E PASS PASS ATE_IND.1.2E PASS AVA AVA_VAN.1 AVA_VAN.1.1E PASS PASS PASS AVA_VAN.1.2E PASS AVA_VAN.1.3E PASS [Table 5] Evaluation Result Summary 10. Recommendations The TOE security functionality can be ensured only in the evaluated TOE operational environment with the evaluated TOE configuration, thus the TOE shall be operated by complying with the followings: ⚫ The administrator should periodically check the free space of the audit data storage in preparation for the loss of the audit records, and perform backups of the audit records so that the audit records are not exhausted. ⚫ The Server(TOE) must be installed and operated in a physically secure environment that is accessible only to authorized administrators and should not allow remote administration from outside. ⚫ If a cryptographic key is lost due to administrator's wrong cryptographic key Certification Report Page 17 management, document users may not be able to decrypt the encrypted file stored on the user's PC, so administrator has to be careful with cryptographic key management. ⚫ If the TOE is operated in a ‘Information system encryption’ type defined in the PP [3], it is recommended that those who are good at using the API. 11.
