Executive Summary This report describes the certification result drawn by the certification body on the results of the APE evaluation of Korean National Protection Profile for Database Encryption V3.1 (“PP” hereinafter) [1] with reference to the Common Criteria for Information Technology Security Evaluation (“CC” hereinafter) [2]. It describes the evaluation result and its soundness and conformity. The authors of the PP [1] are National Security Research Institute (NSR). The Target of Evaluation (TOE) in the PP [1] is Database Encryption designed to prevent the unauthorized disclosure of confidential information by encrypting the database. Also, the TOE shall provide a variety of security features: security audit, the identification and authentication including mutual authentication between TOE components, security management, the TOE access session management, and the TSF protection function, etc. These TOE Security Functional Requirements (SFRs) are outlined in the PP [1]. The evaluation of the PP [1] has been carried out by Korea Security Evaluation Laboratory Co., Ltd. (KSEL) and completed on 10 Oct 2024. This report grounds on the evaluation technical report (ETR) KSEL had submitted [6]. The evaluation of the PP [1] was performed in accordance with the APE (Protection Profile Evaluation) requirements in CC Part 3 and the Common Methodology for Information Technology Security Evaluation (“CEM” hereinafter) [3]. The PP [1] does not claim conformance to any other Protection Profile. All Security Assurance Requirements (SARs) in the PP [1] are based only upon assurance component in CC Part 3, and the assurance package is EAL1 augmented by ATE_FUN.1. Therefore, the PP [1] is CC Part 3 conformant. The Security Functional Requirements (SFRs) are based upon both functional components in CC Part 2 and newly defined components in the Extended component definition chapter of the PP [1]. Therefore, the PP [1] is CC Part 2 extended. The PP [1] requires strict conformance. The operational environment of the Database Encryption is as shown in in [Figure 1], [Figure 2], [Figure 3], and [Figure 4].

Security Policy The PP shall comply with the following Organizational Security Policies. Refer to the PP chapter 3.3 for details. - P.AUDIT - P.SECURE_OPERATION - P.CRYPTO_STRENGTH 4. Assumptions and Clarification of Scope The TOE defined in the PP [1] is the Database Encryption. The TOE of the PP shall be installed and operated with the following assumptions in consideration. Refer to the PP chapter 3.4 for details. - A.PHYSICAL_CONTROL - A.TRUSTED_ADMIN - A.SECURE_DEVELOPMENT - A.OPERATION_SYSTEM_REINFORCEMENT 5. Results of the Evaluation The PP [1] claims EAL1+ (ATE_FUN.1). The evaluation facility provided the evaluation result in the ETR [6] which references a Single Evaluation Report for APE requirements and Observation Reports. The evaluation result was based on the CC [2] and CEM [3]. As a result of the evaluation, the verdict PASS is assigned to all assurance components of APE. Certification Report Page 10 5.1 Protection Profile Evaluation (APE) The PP Introduction correctly identifies the PP, and the PP reference and the TOE overview are consistent with each other. Therefore, the verdict PASS is assigned to APE_INT.1. The Conformance Claim properly describes how the PP conforms to the CC and packages. Therefore, the verdict PASS is assigned to APE_CCL.1. The Security Problem Definition clearly defines the security problem intended to addressed by TOE and its operational environment. Therefore, the verdict PASS is assigned to APE_SPD.1 The Security Objectives for the operational environment from the PP is clearly defined. Therefore, the verdict PASS is assigned to APE_OBJ.1. The Extended Components Definition has been clearly and unambiguously defined, and it is necessary. Therefore, the verdict PASS is assigned to APE_ECD.1. The Security Requirements is defined clearly and unambiguously, and it is internally consistent. Therefore, the verdict PASS is assigned to APE_REQ.1. Thus, the PP is sound and internally consistent, and suitable to be used as the basis for writing a direct rationale ST or another direct rationale PP. The verdict PASS is assigned to the assurance class APE. 5.2 Evaluation Result Summary Assurance Class Assurance Component Evaluator Action Elements Verdict Evaluator Action Elements Assurance Component Assurance Class APE APE_INT.1 APE_INT.1.1E PASS PASS PASS APE_CCL.1 APE_CCL.1.1E PASS PASS APE_SPD.1 APE_SPD.1.1E PASS PASS APE_OBJ.1 APE_OBJ.1.1E PASS PASS APE_ECD.1 APE_ECD.1.1E PASS PASS APE_ECD.1.2E PASS APE_REQ.1 APE_REQ.1.1E PASS PASS [Table 2] Evaluation Result Summary Certification Report Page 11 6. Recommendations The PP [1] defines the minimum security requirements for Database Encryption, and requires an ST or another PP claiming this PP [1] to fulfill the CC requirements for strict conformance. If the TOE defined in the ST which claims conformance to the PP [1] implements additional security features, then it is strongly recommended the ST author to define additional security functional requirements in accordance with the TOE implementation. 7.
