Executive Summary This report describes the certification result drawn by the certification body on the results of the evaluation of SafeDB V4.0 of INITECH Co., Ltd. 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 Target of Evaluation (TOE) is database encryption software that encrypts and decrypts the user data in a column of a database to be protected. The TOE consists of SafeDB Policy Server, SafeDB Manager, SafeDB Agent, SafeDB Plug-In, SafeDB SDK for Java, and SafeDB SDK for C. SafeDB Policy Server allows authorized administrators to manage security functions and TSF data such as cryptographic operation policies and keys, SafeDB Manager provides management interfaces to authorized administrators, SafeDB Agent fetches security policies and data encryption keys from SafeDB Policy Server, and SafeDB Plug-In encrypts and decrypts the user data based on the policies. SafeDB SDK for Java and SafeDB SDK for C behave the same way as SafeDB Plug-In does. The TOE includes cryptographic modules (INISAFE Crypto for Java v4.1, INISAFE Crypto for C V5.3) validated under the Korea Cryptographic Module Validation Program (KCMVP). There are two types of the TOE operational environments: plug-in and API types. In the plug-in type, SafeDB Plug-In is installed in a database server, while SafeDB SDK(SafeDB SDK for Java and SafeDB SDK for C) is installed in an application server in the API type. The evaluation of the TOE has been carried out by Telecommunications Technology Association (TTA) and completed on March 8, 2019. 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 PP for Database Encryption V1.0 [7]. 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 the PP [7]. Therefore, 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 newly defined components in the Extended Component Definition chapter of 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] and [Figure 2] show the operational environments of the TOE.

Security Policy The ST [6] for the TOE claims strict to the Korean National PP for Database Encryption V1.0 [7], and complies security policies defined in the PP [7] by security requirements. Thus, the TOE provides security features defined in the PP [7] as follows: z Security audit: The TOE generates audit records of security relevant events such as the start-up/shutdown of the audit functions, integrity violation, self-test failures, and stores them in the DBMS. z Cryptographic support: The TOE performs cryptographic key management such as key generation, distribution, and destruction, and cryptographic operations such as encryption and decryption using the cryptographic modules (INISAFE Crypto for Java v4.1, INISAFE Crypto for C V5.3) validated under the KCMVP. z User data protection: The TOE provides encryption and decryption for the user data in a column of a database. z Identification and authentication: The TOE identifies and authenticates the administrators using their ID/password and mutually authenticates TOE components. z Security management: The TOE allows only an authorized administrator to access the management interface provided by the TOE. z Protection of the TSF: The TOE implements secure communications between the TOE components to protect the transmitted data. The TOE encrypts the stored TSF data to protect them from unauthorized exposure and modification. Certification Report Page 11 The TOE performs self-tests on the TOE components, which includes the self- test on the validated cryptographic module. z TOE access: The TOE manages authorized administrators’ sessions based on access IP addresses and administrator rights, and terminates the sessions after predefined time interval of inactivity. 4. Assumptions and Clarification of Scope There is no explicit Security Problem Definition chapter, therefore no Assumptions section in the low assurance ST. Some security aspects of the operational environment are added to those of the PP [7] in which the TOE will be used or is intended to be used (For the detailed and precise definition of the security objectives of the operational environment, refer to the ST [6], chapter 3.): 5. Architectural Information The TOE is software consisting of the following components: z SafeDB Policy Server provides security features of identification and authentication of administrators, cryptographic key managements, and security management to the TOE and TSF data. z SafeDB Manager provides management interfaces to authorized administrators. z SafeDB Agent provides CLI-based management interface to an authorized administrator. z SafeDB Agent fetches security policies and data encryption key from SafeDB Policy Server, then provides those data to SafeDB Plug-In, SafeDB SDK for Java, and SafeDB SDK for C. z SafeDB Plug-In, SafeDB SDK for Java, SafeDB SDK for C encrypt and decrypt the user data in a column of a database. Note that all the five components perform the same functionalities of audit data generation, cryptographic key management, cryptographic operations, protection of TSF data, and mutual authentication between the components. For the detailed description on the architectural information, refer to the ST [6], chapter 1.4.3. Certification Report Page 12 6. Documentation The following documentations are evaluated and provided with the TOE by the developer to the customer. Identifier Release Date CCP.C_SB40_Preparative Procedures (PRE)_V1.4 V1.4 Feb. 14, 2019 CCP.C_SB40_Operational Guidance(OPE)_V1.4 V1.4 Feb. 14, 2019 [Table 5] Documentation 7. TOE Testing The developer took a testing approach based on the security services provided by each TOE components based on the operational environment of the TOE. Each test case includes the following information: z Test no.: Identifier of each test case z Test Purpose: Includes the security functions and modules to be tested z Test Configuration: Details about the test configuration z Test Procedure detail: Detailed procedures for testing each security function z Expected result: Result expected from testing z Actual result: Result obtained by performing testing z 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 installed and prepared the TOE in accordance to the preparative procedures, and conducted independent testing based upon test cases devised by the evaluator. The TOE and test configuration are identical to the developer’s tests. Also, the evaluator conducted vulnerability analysis and penetration testing based upon test cases devised by the evaluator resulting from the independent search for potential vulnerabilities. The evaluator’s testing effort, the testing approach, configuration, depth, and results Certification Report Page 13 are summarized in the ETR [5]. 8. Evaluated Configuration The TOE is SafeDB V4.0 (version number V4.0.3). See table 3 for detailed information on the TOE components. The TOE is installed from the CD-ROM distributed by INITECH Co., Ltd. After installing the TOE, an administrator can identify the complete TOE reference using the product’s Info check menu. 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 [5] which references Single Evaluation Reports for each assurance requirement and Observation Reports. The evaluation result was 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 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 it is internally Certification Report Page 14 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 Life Cycle Support Evaluation (ALC) The developer has uniquely identified the TOE. Therefore, the verdict PASS is assigned to ALC_CMC.1. The configuration list includes the TOE and the evaluation evidence required by the SARs in the ST. Therefore, the verdict PASS is assigned to ALC_CMS.1. 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 Development Evaluation (ADV) The developer has provided a high-level description of at least the SFR-enforcing and Certification Report Page 15 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. 9.5 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 TSF, the evaluator confirmed that the TOE 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. 9.6 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, 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 Certification Report Page 16 Assurance Class Assurance Component Evaluator Action Elements Verdict Evaluator Action Elements Assurance Component Assurance Class 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 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 PASS AGD_OPE.1 AGD_OPE.1.1E PASS PASS ADV ADV_FSP.2 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 6] Evaluation Result Summary 10.
