Executive Summary This report describes the certification result drawn by the certification body on the results of the EAL1+ evaluation of SafeDB V4.1(“TOE” hereinafter) with reference to the Common Criteria for Information Technology Security Evaluation (“CC” hereinafter) [1]. It describes the evaluation result and its soundness and conformity. The TOE is provided as software and provides the encryption/decryption function for the user data by each column of Database. The TOE consists of SafeDB Policy Server that manages cryptographic operation policies and keys, SafeDB Manager that performs web security management, SafeDB Agent that is received security policy from SafeDB Policy Server and deploy the policy to SafeDB SDK and SafeDB Plug-In, SafeDB SDK which supports Java / C language, and SafeDB Plug-In applied to DBMS. When the security administrator input policy information through the SafeDB Manager, the security policy is managed by the SafeDB Policy Server. The security policy is distributed as SafeDB Agent, and it is referenced in SafeDB SDK and SafeDB Plug-In cryptographic operation based on the received security policy. The TOE is required to use the cryptographic algorithm validated in the Korea Cryptographic Module Validation Program (KCMVP). The TOE is used to encrypt the user data according to the policy set by the authorized administrator to prevent the unauthorized disclosure of the confidential information. The TOE includes a variety of security features: security audit function that records the audit data for the critical events related to the security and management functions, identification and authentication function including verification of an administrator identity and authentication failures handling, TSF protection function such as protecting the data stored in the storage controlled by the TSF, TSF self-testing and integrity check. In addition, the TOE provides security management functions to define the administrator role and configure security functions, the TOE access function to manage the authorized administrator’s interacting session. Certification Report Page 6 The evaluation of the TOE has been carried out by Telecommunications Technology Association (TTA) and completed on June 25, 2024. This report grounds on the evaluation technical report (ETR) TTA had submitted [5] and the Security Target (ST) [6]. The ST claims strict conformance to the Korean National Protection Profile for Data Encryption V1.1 [3]. All Security Assurance Requirements (SARs) in the ST are based only upon assurance component in CC Part 3. 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. The operational environment of the TOE is shown in [Figure 1, 2] TOE Operational Environment. The operational environment of the TOE includes all the two types (API type, plug-in type) defined in the PP [3].

And the guidance documents listed in this report chapter 6 [Table 4] were evaluated with the TOE. Certification Report Page 13 9. Results of the Evaluation The evaluation facility wrote the evaluation results in the ETR [5] which references Single Evaluation Reports for each assurance requirement and Observation Reports. The evaluation results were based on the CC [1] and CEM [2]. 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. 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 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. Certification Report Page 14 The verdict PASS is assigned to the assurance class ADV. 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 Life Cycle Support Evaluation (ALC) The developer has clearly 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. 9.5 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 behaves as specified in the functional specification and guidance documentation. Certification Report Page 15 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. 9.6 Vulnerability Assessment (AVA) By penetration 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 Results 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 ASE_TSS.1 ASE_TSS.1.1E PASS PASS ASE_TSS.1.2E PASS Certification Report Page 16 Assurance Class Assurance Component Evaluator Action Elements Verdict Evaluator Action Elements Assurance Component Assurance Class ADV ADV_FSP.1 ADV_FSP.1.1E PASS PASS PASS ADV_FSP.1.2E 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 ALC ALC_CMC.1 ALC_CMC.1.1E PASS PASS PASS ALC_CMS.1 ALC_CMS.1.1E PASS 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 Results Summary 10.
