Executive Summary This report describes the certification result drawn by the certification body on the results of the Document Security V5.0 developed by SoftCamp 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” hereinafter) is Electronic Document Encryption designed to protect important documents managed by the organization based on the encryption/decryption. Also, the TOE provide 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 October 24, 2019. This report grounds on the Evaluation Technical Report (ETR) [4] KOSYAS had submitted and the Security Target (ST) [5]. The ST claims strict conformance to the Korean National PP for Electronic Document Encryption V1.0 [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. [Figure 1] shows the operational environment of the TOE. TOE is composed of the Document Security Server V5.0 (hereinafter ‘Server’) which manage security policy and cryptographic key, Document Security Client V5.0 (hereinafter ‘Client’) which encrypt/decrypt Electronic Document, and Document Security Console V5.0 (hereinafter ‘Console’) which provide security management interface.

Security Policy The TOE complies security policies defined in the ST [5] by security requirements. Thus the TOE provides following security features. For more details refer to the ST [5]. TSF Explanation 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. Cryptographic Support The TOE performs cryptographic operation such as encryption/decryption, and cryptographic key management such as key generation/distribution/destruction using XecureCrypto v2.0.1.1 and SCCrypto v1.0. User Data Protection The TOE protects user’s documents by making them Secured Documents by means of encrypting them and controlling access to them in accordance to the access control policy per user set by the administrator. Identification and Authentication The TOE identifies and authenticates the administrators and document users based on ID/PW. Security Management Server(TOE) provides functions such as TOE security function management, security attribute management and TSF data management to the authorized administrator. Protection of the TSF The TOE provides secure communications amongst TOE components to protect confidentiality and integrity of the transmitted data between them. The TOE also protects TSF data against unauthorized exposure and modification through encryption and proprietary encoding. TOE Access The TOE manages the authorized administrator’s access to itself by terminating interactive sessions after defined time interval of their inactivity. [Table 4] The TOE Security Functions 4. Assumptions and Clarification of Scope There are no explicit Assumptions in the Security Problem Definition in the Low Assurance ST.

TOE Testing The developer took a testing approach based on the security services provided by each TOE component based on the operational environment of the TOE. Each test case includes the following information:  Test no. and conductor: Identifier of each test case and its conductor  Test Purpose: Includes the security functions and modules 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 [4]. 8. Evaluated Configuration The TOE is software consisting of the following components: TOE: Document Security V5.0 Version: V5.0.0.6 - Document Security Server V5.0 (V5.0.0.3) - Document Security Client V5.0 (V5.0.0.6) - Document Security Console V5.0 (V5.0.0.4) 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, Certification Report Page 13 [Table 6] were evaluated with the TOE 9. Results of the Evaluation The evaluation facility provided the evaluation result in the ETR [4] 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 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 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 Certification Report Page 14 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 Development Evaluation (ADV) The functional specifications specifies 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. 9.5 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. Therefore the verdict PASS is assigned to ATE_IND.1. Certification Report Page 15 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 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 ASE_TSS.1 ASE_TSS.1.1E PASS PASS ASE_TSS.1.2E PASS ALC ALC_CMS.1 ALC_CMS.1.1E PASS PASS PASS ALC_CMC.1 ALC_CMC.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.1 ADV_FSP.1.1E PASS PASS PASS ADV_FSP.1.2E 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 Certification Report Page 16 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. 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 storage is 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.  The administrator shall maintain a safe state such as application of the latest security patches, eliminating unnecessary service, change of the default ID/password, etc., of the operating system and DBMS in the TOE operation.  If a cryptographic key is lost due to administrator's neglectful cryptographic key 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 11.
