1. Executive Summary
This report describes the certification result drawn by the certification body on the
results of the evaluation of Pass-Ni SSO v4.0 of UbiNtisLab 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 Single Sign-On (SSO) software to be used to enable
the user to access various business systems and use the service through a single user
login without additional login action. The TOE is comprised of four software
components: Pass-Ni SSO Server, Pass-Ni SSO Agent for JAVA, Pass-Ni SSO Agent
for ASP.NET, and Pass-Ni SSO Agent for PHP. Pass-Ni SSO Server performs functions
such as user login processing, authentication token issuance and policy setting, while
Pass-Ni SSO Agent that is installed in each business system validates the
authentication token through interworking with Pass-Ni SSO Server. It also includes
preparative procedures that describe the procedures for secure acceptance and
installing the TOE, and operational guidance that specify how to use the TOE safely.
The TOE includes a cryptographic module validated under the Korea Cryptographic
Module Validation Program (KCMVP).
The evaluation of the TOE has been carried out by Korea System Assurance (KOSYAS)
and completed on February 21, 2019. This report grounds on the evaluation technical
report (ETR) KOSYAS had submitted [5] and the Security Target (ST) [6].
The ST claims strict conformance to the Korean National Protection Profile for Single
Sign On 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 PP, and the TOE satisfies the SFRs in the ST. Therefore, the ST and the resulting
TOE is CC Part 2 extended.

3. Security Policy
The ST [6] for the TOE claims strict conformance to the Korean National Protection
Profile for Single Sign On 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
including the start-up/shutdown of the audit functions and all auditable events
listed in ST [6] such as the results of the TOE security functionality (TSF) self-
tests and modifications to the values of TSF data. The TOE stores the audit
recodes in the DBMS and provides the recodes for the authorized
administrator.
z Cryptographic support: The TOE performs cryptographic key management
such as key generation, distribution, and destruction, and cryptographic
operations such as encryption, decryption, and hash using the cryptographic
module (Pass-Ni Crypto V1.1) validated under the KCMVP.
z Identification and authentication: The TOE identifies and authenticates the
Certification Report Page 10
administrators and end-users using their ID/password and mutually
authenticates TOE components. The TOE performs authentication token
management such as token issuance, verification, and destruction. The TOE
authenticates end-users based on the authentication tokens issued during the
initial authentication procedure using their ID/password.
z Security management: The TOE allows only authorized administrators 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.
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
attributes such as connection IP address. The TOE terminates administrators’
and end-users’ sessions after predefined time interval of inactivity.
z Trusted channel: The TOE implements secure communications between the
TOE and the SMTP server in the operational environment.
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 Pass-Ni SSO Server provides security features of audit data generation,
identification and authentication of users (administrators and end-users),
cryptographic key management, cryptographic operations, security
management to the TOE and TSF data, protection of TSF data, access control
to Pass-Ni SSO Server, and the trusted channel between the TOE and the
Certification Report Page 11
SMTP server.
z Pass-Ni SSO Agent (Pass-Ni SSO Agent for JAVA, Pass-Ni SSO Agent for
ASP.NET, Pass-Ni SSO Agent for PHP) authenticates end-users based on their
authentication tokens issued by Pass-Ni SSO Server, performs cryptographic
key management and cryptographic operations related to the mutual
authentication and the internal TSF data transfer protection, and protects
transmitted and stored TSF data.
For the detailed description on the architectural information, refer to the ST [6], chapter
1.4.3.

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. In addition, 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 confirmed that all the actual testing
results correspond to the expected testing results.
The evaluator’s testing effort, the testing approach, configuration, depth, and results
are summarized in the ETR [5].
8. Evaluated Configuration
The TOE is Pass-Ni SSO v4.0 (version number 4.0.005). See table 3 for detailed
information on the TOE components.
The TOE is installed from a CD-ROM distributed by UbiNtisLab Co., Ltd. After the
installation of the TOE, an administrator can identify the TOE version through 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.
Certification Report Page 13
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 PP 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 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 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.
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.
Certification Report Page 14
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 provided by the developer specify 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 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.
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
Certification Report Page 15
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:
z The TOE must be installed and operated in a physically secure environment
accessible only by authorized administrators and should not allow remote
management from outside.
z 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.
z The administrator should periodically checks a spare space of audit data
storage in case of the audit data loss, and carries out the audit data backup to
prevent audit data loss.
z The developer who uses the TOE to interoperate with the user identification
and authentication function in the operational environment of the business
system shall ensure that the security functions of the TOE are securely applied
in accordance with the requirements of the manual provided with the TOE.
