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 licence 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, 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
The presence of the Common Criteria Recognition Arrangement (CCRA) and the SOG-IS logos on the
certificate indicates that this certificate is issued in accordance with the provisions of the CCRA and
the SOG-IS Mutual Recognition Agreement (SOG-IS MRA) and will be recognised by the participating
nations.
International recognition
The CCRA was signed by the Netherlands in May 2000 and provides mutual recognition of certificates
based on the Common Criteria (CC). Since 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.
For details of the current list of signatory nations and approved certification schemes, see
http://www.commoncriteriaportal.org.
European recognition
The SOG-IS MRA Version 3, effective since April 2010, provides mutual recognition in Europe of
Common Criteria and ITSEC certificates at a basic evaluation level for all products. A higher
recognition level for evaluation levels beyond EAL4 (respectively E3-basic) is provided for products
related to specific technical domains. This agreement was signed initially by Finland, France,
Germany, The Netherlands, Norway, Spain, Sweden and the United Kingdom. Italy joined the SOG-IS
MRA in December 2010.
For details of the current list of signatory nations, approved certification schemes and the list of
technical domains for which the higher recognition applies, see https://www.sogis.eu.

1 Executive Summary
This Certification Report states the outcome of the Common Criteria security evaluation of the Huawei
CloudEngine S8700 Series Switches’ YunShan Software V600R021C10SPC500. The developer of
the Huawei CloudEngine S8700 Series Switches’ YunShan Software V600R021C10SPC500 is
Huawei Technologies Co., Ltd. located in Shenzhen, Peoples Republic of China 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 software running on the CloudEngine S8700 Series. These switches consist of both
hardware (non-TOE) and software. The software running on the switches is called Yunshan software
developed by Huawei. Yunshan software provides extensive security features, including different
interfaces with according access levels for administrators, enforcing authentications prior to
establishment of administrative sessions, auditing of security-relevant management activities. The
TOE software consists of TSF and non-TSF parts. These are shown in section 2.4.
The TOE has been evaluated by Riscure B.V. in Delft. The evaluation was completed on 10 February
2023 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 Huawei CloudEngine S8700 Series Switches’
YunShan Software V600R021C10SPC500, 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 Huawei CloudEngine S8700 Series Switches’ YunShan Software
V600R021C10SPC500 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 provide sufficient
evidence that the TOE meets the EAL4 augmented (EAL4+) assurance requirements for the evaluated
security functionality. This assurance level is augmented with ALC_FLR.2 (Flaw Reporting
Procedures).
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] (Parts I, II and III).
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. Note that the certification results apply only to the
specific version of the product as evaluated.

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.
2.4 Architectural Information
The TOE scope consists of the software running in the router device. The hardware is out of TOE
scope.
The underlying OS on which the TOE software is supported consists in a Linux operating system. The
OS provides basic services including memory management, scheduling management, file
management, and device management.
The Yunshan software is a network operating platform, which has a distributed, multi-process, and
component-based architecture. It builds upon the hardware development trend and will meet carriers'
service requirements.
The Yunshan software is responsible for functional management, routing information generation,
receiving generated routing information and formatting them into hardware-specific data to direct traffic
forwarding.
The diagram below describes which modules of the Yunshan software are part of the TSF and which
ones are not. Only the part of the TOE highlighted in green is included in the TSF.
Architecture and boundaries of the Target of Evaluation
The Yunshan software consists of Management Plane, Control Plane and Data Plane.
In TSF scope:
• Management Plane (MP), implements management for external access, management for
system configuration, information output on Yunshan software, NTP.
• Framework, implements system internal scheduling, communication, management of signals,
events, timers, etc. System security functions are also implemented at this plane.
In TOE scope:
• Control Plane (CP) controls and manages the operation of all network protocols. The control
plane provides various network information and forwarding query entries required for data
processing and forwarding on the Data Plane;

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 evaluator repeated developer test cases which covered audit trail, authentication failure
management, password Management, authentication aspects of SSH and administrator privileges
In addition, the evaluator devised additional independent evaluator tests to provide further assurance
of the functional security. These focussed on command privileges and password controls.
2.6.2 Independent penetration testing
The TOE is a network server that performs routing. Therefore, the vulnerability analysis is conducted
using the network attack methods, and is structured in the following phases:
• Information Gathering and Potential Vulnerability Identification: understand network structures,
server properties using port scanning, detection of running services etc. and conducting public
vulnerability searches to identify potential vulnerabilities
• Exploitation: get some first unprivileged access e.g. by manipulating file upload mechanisms,
authentication bypass, password attacks etc.
• Privilege escalation: escalate to extended / root privileges to gather further information on
operating system properties, application services, file-system structures to get deeper into the
system and break security features
The vulnerability analysis took information from the design assessment of the TOE into account. The
ADV/ATE documentation along with the source code review that was done as part of the combined
AVA/ADV_IMP assessment also provided insight into areas that could be potentially vulnerable.
These were then testing in the penetration testing phase.
To rate the difficulties to exploit potential vulnerabilities the evaluation used the standard rating
methodology from the Common Criteria Standard. The reason for this choice is that the standard
rating focusses on the efforts of creating / identifying a potential exploit which is the most important

factor as exploits for this type of product usually have to be deployed remotely and therefore scale
quite well. Thus, there is no reason for applying a specific rating scheme which for example explicitly
splits identification and exploitation efforts.
The total test effort expended by the evaluators was 1 week. During that test campaign, 100% of the
total time was spent on logical tests.
2.6.3 Test configuration
The configuration of the sample used for independent evaluator testing and penetration testing was
the same as described in the [ST].
2.6.4 Test 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 Reused Evaluation Results
There has been extensive reuse of the ALC aspects for the sites involved in the development and
production of the TOE, by use of 5 Site Technical Audit Reports.
No sites have been visited as part of this evaluation.
2.8 Evaluated Configuration
The TOE is defined uniquely by its name and version number Huawei CloudEngine S8700 Series
Switches’ YunShan Software V600R021C10SPC500.
The TOE can be identified by running the display version slot [slot-id] command through the console
or SSH interface as described in the [AGD_PRE].
2.9 Evaluation Results
The evaluation lab documented their evaluation results in the [ETR], which references an ASE
Intermediate Report and other evaluator documents, and Site Technical Audit Report(s) for the site(s)
[STAR] 2.
The verdict of each claimed assurance requirement is “Pass”.
Based on the above evaluation results the evaluation lab concluded the Huawei CloudEngine S8700
Series Switches’ YunShan Software V600R021C10SPC500, to be CC Part 2 extended, CC Part 3
conformant, and to meet the requirements of EAL 4 augmented with ALC_FLR.2. 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 “Documentation” contains necessary information about
the usage of the TOE.
In addition, all aspects of assumptions, threats and policies as outlined in the Security Target not
covered by the TOE itself must 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. For the evolution of attack methods and techniques to be covered, the
customer should define the period of time until a re-assessment for the TOE is required and thus
requested from the sponsor of the certificate.
2 The Site Technical Audit Report contains information necessary to an evaluation lab and
certification body for the reuse of the site audit report in a TOE evaluation.
