1. Executive Summary
This report describes the certification result drawn by the certification body on the
results of the evaluation of CubeOne V3.0 of eGlobal Systems 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 to prevent
unauthorized exposure of the information from DBMS. The TOE is provided as
software and provides the following security features: security audit, cryptographic
operations using validated cryptographic module, user identification and authentication
including mutual authentication between the TOE components, security management,
the TOE access session management, and the TSF protection.
The TOE is comprised of the following software components: CubeOne Manager,
CubeOne Server, CubeOne Security Server. The TOE uses cryptographic modules
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, CubeOne Server is installed in a database server. In the API type,
CubeOne Server is installed in an application server. The component CubeOne
Manager provides security management function to an authorized policy administrator.
An authorized log administrator can access to CubeOne Security Server to check if
there is security alert and audit log.
The evaluation of the TOE has been carried out by Korea System Assurance (KoSyAs)
and completed on 24 November 2023. This report grounds on the evaluation technical
report (ETR) KoSyAs had submitted [5] and the Security Target (ST) [6][7].
The ST claims strict conformance to the Korean National Protection Profile for
Database Encryption V1.1 [9]. 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 [9]. 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 environment of the TOE for the plug-in
and API types, respectively.

3. Security Policy
The ST [6][7] for the TOE claims strict conformance to the National Protection Profile
for Database Encryption V1.1 [9], and complies security policies defined in the PP [9]
by security requirements. Thus, the TOE provides security features defined in the PP [9]
as follows:
 Security audit: The TOE generates audit records of security relevant events
including the start-up/shutdown of the audit functions, integrity violation and
self-test failures, and stores them in the DBMS.
 Cryptographic support: The TOE performs cryptographic operations and
cryptographic key management operations using cryptographic module (COLib
V1.2.0) validated under the KCMVP.
 Identification and authentication: The TOE provides the identification and
authentication operations for administrators using ID and password. The TOE
mutually authenticates TOE components when they communicate each other.
 Security management: Security management of the TOE is restricted to only
the authorized administrator who can access the management interface
provided by TOE.
Certification Report Page 11
 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 provides the self-test and integrity verification
functions of TSF execution code and TSF data.
 TOE access: The TOE manages the authorized administrator’s access to itself
by terminating and lock interactive sessions after predefined time interval of
their inactivity for CubeOne Security Server and CubeOne Manager,
respectively.
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 [9] 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][7], chapter 3.).
5. Architectural Information
The TOE is software consisting of the following components:
 CubeOne Manager
 CubeOne Server, and
 CubeOne Security Server.

7. TOE Testing
The developer took a testing approach based on the APIs and security services based
on the operational environment of the TOE. 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
The evaluator set up the test configuration and testing environment, which are
consistent with the ST [6][7]. The evaluator performed all tests provided by developer,
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
are summarized in the ETR [5].
8. Evaluated Configuration
The TOE is CubeOne V3.0 (version number rev.0025). See table 3 for detailed
information on the TOE components.
The TOE is installed from the CD-ROM distributed by eGlobal Systems Co., LTD. After
installing the TOE, the customer can check the TOE version from ‘About CubeOne’
menu in the CubeOne Manager. The guidance documents listed in this report chapter 6,
[Table 5] were evaluated with the TOE.
Certification Report Page 14
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
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
Certification Report Page 15
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 consider 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
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).
Certification Report Page 16
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.

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 TOE shall be in a physically secure environment to which only the
authorized administrator is allowed to access. The TOE shall not allow remote
management.
 The authorized administrator of the TOE shall preserve a secure state of the
TOE by various methods such as keeping the OS and the DBMS up to date
with the latest patch, eliminating unnecessary services, and changing the
default ID and password.
 The administrator shall periodically check a spare space of audit data storage
in case of the audit data loss, and carries out the audit data to prevent audit
data loss.
 In order to install and operate the TOE, it is recommended that developers of
an application server should fully understand the guidance documents (the
preparative procedures guidance and the operational user guidance).
