Foreword
The Netherlands Scheme for Certification in the Area of IT Security (NSCIB) provides a third-party
evaluation and certification service for determining the trustworthiness of Information Technology (IT)
security products. Under this NSCIB, TÜV Rheinland Nederland B.V. has the task of issuing
certificates for IT security products, as well as for protection profiles and sites.
Part of the procedure is the technical examination (evaluation) of the product, protection profile or site
according to the Common Criteria assessment guidelines published by the NSCIB. Evaluations are
performed by an IT Security Evaluation Facility (ITSEF) under the oversight of the NSCIB Certification
Body, which is operated by TÜV Rheinland Nederland B.V. in cooperation with the Ministry of the
Interior and Kingdom Relations.
An ITSEF in the Netherlands is a commercial facility that has been licensed by TÜV Rheinland
Nederland B.V. to perform Common Criteria evaluations; a significant requirement for such a license is
accreditation to the requirements of ISO Standard 17025 “General requirements for the accreditation
of calibration and testing laboratories”.
By awarding a Common Criteria certificate, TÜV Rheinland Nederland B.V. asserts that the product or
site complies with the security requirements specified in the associated (site) security target, or that
the protection profile (PP) complies with the requirements for PP evaluation specified in the Common
Criteria for Information Security Evaluation. A (site) security target is a requirements specification
document that defines the scope of the evaluation activities.
The consumer should review the (site) security target or protection profile, in addition to this
certification report, in order to gain an understanding of any assumptions made during the evaluation,
the IT product's intended environment, its security requirements, and the level of confidence (i.e., the
evaluation assurance level) that the product or site satisfies the security requirements stated in the
(site) security target.

Recognition of the certificate
Presence of the Common Criteria Recognition Arrangement and SOG-IS logos on the certificate
indicates that this certificate is issued in accordance with the provisions of the CCRA and the SOG-IS
agreement and will be recognised by the participating nations.
International recognition
The CCRA has been signed by the Netherlands in May 2000 and provides mutual recognition of
certificates based on the CC. Starting September 2014 the CCRA has been updated to provide mutual
recognition of certificates based on cPPs (exact use) or STs with evaluation assurance components
up to and including EAL2+ALC_FLR. The current list of signatory nations and approved certification
schemes can be found on: http://www.commoncriteriaportal.org.
European recognition
The European SOGIS-Mutual Recognition Agreement (SOGIS-MRA) version 3 effective from April
2010 provides mutual recognition of Common Criteria and ITSEC certificates at a basic evaluation
level for all products. A higher recognition level for evaluation levels beyond EAL4 (resp. E3-basic) is
provided for products related to specific technical domains. This agreement was initially signed by
Finland, France, Germany, The Netherlands, Norway, Spain, Sweden and the United Kingdom. Italy
joined the SOGIS-MRA in December 2010. The current list of signatory nations, approved certification
schemes and the list of technical domains for which the higher recognition applies can be found on:

1 Executive Summary
This Certification Report states the outcome of the Common Criteria security evaluation of the Cisco
Unified Computing System Standalone, Version 4.0(4i). The developer of the Cisco Unified Computing
System Standalone, Version 4.0(4i) is Cisco Systems Inc located in San Jose, USA and they also act
as the sponsor of the evaluation and certification. A Certification Report is intended to assist
prospective consumers when judging the suitability of the IT security properties of the product for their
particular requirements.
The TOE is a network device that consists of hardware and software components that support Cisco
Unified Systems, running in standalone mode. The TOE features a role based access control policy to
control the separation of administrative duties and provide a security log of all changes made.
In standalone mode each UCS C-Series and S Series server runs as an independent system. The
Cisco Integrated Management Controller (CIMC) manages each platform as an individual entity in a
Data Centre or across remote locations.
The TOE has been evaluated by Brightsight B.V. located in Delft, The Netherlands. The evaluation
was completed on 21 April 2020 with the approval of the ETR. The certification procedure has been
conducted in accordance with the provisions of the Netherlands Scheme for Certification in the Area of
IT Security [NSCIB].
The scope of the evaluation is defined by the security target [ST], which identifies assumptions made
during the evaluation, the intended environment for the Cisco Unified Computing System Standalone,
Version 4.0(4i), the security requirements, and the level of confidence (evaluation assurance level) at
which the product is intended to satisfy the security requirements. Consumers of the Cisco Unified
Computing System Standalone, Version 4.0(4i) are advised to verify that their own environment is
consistent with the security target, and to give due consideration to the comments, observations and
recommendations in this certification report.
The results documented in the evaluation technical report [ETR]
1
for this product provides sufficient
evidence that the TOE meets the EAL2.
The evaluation was conducted using the Common Methodology for Information Technology Security
Evaluation, Version 3.1 Revision 5 [CEM] for conformance to the Common Criteria for Information
Technology Security Evaluation, version 3.1 Revision 5 [CC].
TÜV Rheinland Nederland B.V., as the NSCIB Certification Body, declares that the evaluation meets
all the conditions for international recognition of Common Criteria Certificates and that the product will
be listed on the NSCIB Certified Products list. It should be noted that the certification results only apply
to the specific version of the product as evaluated.

2 Certification Results
2.1 Identification of Target of Evaluation
The Target of Evaluation (TOE) for this evaluation is the Cisco Unified Computing System Standalone,
Version 4.0(4i) from Cisco Systems Inc located in San Jose, USA.
The TOE is comprised of the following main components:
Delivery
item type
Identifier Version
Hardware
Cisco UCS C-Series Rack Servers (C220 M5, C240 M5, C480
M5 and C480 ML M5)
N/A
Cisco UCS S-Series Rack Servers (S3260 M5) N/A
Virtual Interface Cards (security non-enforcing and listed in [ST]
section 1.3.3)
N/A
Software Cisco Integrated Management Controller (CIMC) 4.0(4i)
To ensure secure usage a set of guidance documents is provided together with the Cisco Unified
Computing System Standalone, Version 4.0(4i). Details can be found in section 2.5 of this report.
2.2 Security Policy
The major security features provided by the TOE are summarized as follows:
The TOE provides audit information to assist the administrator in monitoring the security state of the
TOE as well as trouble shooting various problems that arise throughout the operation of the system.
The TOE provides local administrator authentication using username and password, or authenticate
administration via a remote authentication server. However only one of them can be select at a time,
not both.
The TOE can be managed using the graphical user interface (over TLS 1.2), the command line (over
SSHv2 or by local console access via the RS-232 port), or by manipulating an XML API. The
interfaces all operate on the same XML data structures and provide identical functionality. In addition
the UCS provides SNMPv3 to export system traps and support remote monitoring (read only). This
interface supports SHA authentication and AES-128 encryption for protecting the confidential system
information.
The TOE internally maintains the date and time. This date and time is used as the timestamp that is
applied to audit records generated by the TOE. The TOE provides the Authorized Administrators the
capability to change the timezone in order to update the TOE’s clock to maintain a reliable timestamp.
The timestamp is updated accordingly when the timezone is changed.
Role-Based Access Control (RBAC) is a method of restricting or authorizing system access for users
based on user roles. A role defines the privileges of a user in the system that a user is allowed access.
Because users are not directly assigned privileges, management of individual user privileges is simply
a matter of assigning the appropriate roles.
2.3 Assumptions and Clarification of Scope
2.3.1 Assumptions
The assumptions defined in the Security Target are not covered by the TOE itself. These aspects lead
to specific Security Objectives to be fulfilled by the TOE-Environment. Detailed information on these
security objectives that must be fulfilled by the TOE environment can be found in section 4.2 of the
[ST].

2.3.2 Clarification of scope
The evaluation did not reveal any threats to the TOE that are not countered by the evaluated security
functions of the product.
Note: A syslog server is required for receiving and reviewing audit messages of failed administrative
actions. Successful actions are logged to the local audit logs as well as to the remote syslog server.
Failed authentication attempts are not logged to the local audit log but are sent to a remote syslog
server.
2.4 Architectural Information
The general architecture consists of two subsystems:
 The Processing Node subsystem in which only CMIC chip is the only SFR enforcing part
which provides the following security functions:
o I&A
o Management functions
o Logging
o Secure communication
o Management interfaces:CLI and GUI
 The UCS CIMC Client Subsystem which is a java-based application running in a non-TOE
browser on a non-TOE workstation:
o It is used to connect to the UCS CIMC chip running on the server and perform
management operations.
o It makes no decision as the CIMC chip decides whether actions are allowed.

2.6 IT Product Testing
Testing (depth, coverage, functional tests, independent testing): The evaluators examined the
developer’s testing activities documentation and verified that the developer has met their testing
responsibilities.
2.6.1 Testing approach and depth
The developer tests consisted of 23 tests. These tests covered most of the TSFI and SFRs and
include both positive and negative tests. The developer and evaluator tested using different device
models to maximize the coverage over multiple devices. The evaluator repeated 5 tests putting
emphasis on those tests covering verification of the SSH remote access protocol, verifying user
account privileges, certain claims in the Security Target (e.g. role-based access control) and protection
of audit logs and their time stamp.
In addition to the developer tests, the evaluator derived and executed 10 additional functional tests.
2.6.2 Independent Penetration Testing
The evaluators performed 10 penetration tests. These were derived from a vulnerability analysis
comprised of 3 parts:
1. SFR mapping table
The evaluator applied their knowledge of attacks applicable to the TOE based on the information
gathered from all evaluation evidence.
2. Public domain analysis
The evaluator performed a public domain vulnerability search for TOE specific items (TOE name,
TOE-type, secure libraries, etc.)
The evaluator used the websites provided by NSCIB as a basis to perform the search.
3. Network scanning tools
The evaluator ran vulnerability scanning tools and analysed the results to identify potential
vulnerabilities.
2.6.3 Test Configuration
The following parts made up the TOE under test, and were configured as show in Figure 2:

2.6.4 Testing Results
The testing activities, including configurations, procedures, test cases, expected results and observed
results are summarised in the [ETR], with references to the documents containing the full details.
The developer’s tests and the independent functional tests produced the expected results, giving
assurance that the TOE behaves as specified in its [ST] and functional specification.
No exploitable vulnerabilities were found with the independent penetration tests.
2.7 Re-used evaluation results
There is no re-use of evaluation results in this certification.
2.8 Evaluated Configuration
The TOE is defined uniquely by its name and version number Cisco Unified Computing System
Standalone, Version 4.0(4i). Details of the hardware models included in the TOE are provided in
section 2.1
2.9 Results of the Evaluation
The evaluation lab documented their evaluation results in the [ETR] which references a ASE
Intermediate Report and other evaluator documents.
The verdict of each claimed assurance requirement is “Pass”.
Based on the above evaluation results the evaluation lab concluded the Cisco Unified Computing
System Standalone, Version 4.0(4i), to be CC Part 2 extended, CC Part 3 conformant, and to meet
the requirements of EAL2. This implies that the product satisfies the security requirements specified in
Security Target [ST].
2.10 Comments/Recommendations
The user guidance as outlined in section 2.5 contains necessary information about the usage of the
TOE. Certain aspects of the TOE’s security functionality, in particular the countermeasures against
attacks, depend on accurate conformance to the user guidance of both the software and the hardware
part of the TOE. There are no particular obligations or recommendations for the user apart from
following the user guidance. Please note that the documents contain relevant details with respect to
the resistance against certain attacks.
Note: To record failed authentication attempts, the user needs to configure a remote syslog server.
Successful actions are logged to the local audit logs as well as to the remote syslog server. Failed
authentication attempts are not logged to the local audit log but are sent to a remote syslog server.
In addition all aspects of assumptions, threats and policies as outlined in the Security Target not
covered by the TOE itself need to be fulfilled by the operational environment of the TOE.
The customer or user of the product shall consider the results of the certification within his system risk
management process. In order for the evolution of attack methods and techniques to be covered, he
should define the period of time until a re-assessment for the TOE is required and thus requested from
the sponsor of the certificate.
