1 Executive Summary
This Validation Report (VR) documents the National Information Assurance Partnership (NIAP) assessment
of the evaluation of VMware Horizon Agent 8 2209 (Horizon 8.7) (the Target of Evaluation, or TOE). It
presents the evaluation results, their justifications, and the conformance results. This VR is not an
endorsement of the TOE by any agency of the U.S. Government and no warranty of the TOE is either
expressed or implied.
The evaluation was performed by Leidos Common Criteria Testing Laboratory (CCTL) in Columbia,
Maryland, USA, and was completed in June 2023. The information in this report is largely derived from
the Evaluation Technical Report (ETR) and associated test report written by Leidos. The evaluation
determined that the TOE is Common Criteria Part 2 Extended and Common Criteria Part 3 Extended and
meets the assurance requirements of the following documents:
• Protection Profile for Application Software, Version 1.4, 7 October 2021
• Functional Package for Transport Layer Security (TLS), Version 1.1, February 12, 2019
The TOE is VMware Horizon Agent 8 2209 (Horizon 8.7). The TOE identified in this VR has been evaluated
at a NIAP approved CCTL using the Common Methodology for IT Security Evaluation (Version 3.1, Rev. 5)
for conformance to the Common Criteria for IT Security Evaluation (Version 3.1, Rev. 5). The evaluation
has been conducted in accordance with the provisions of the NIAP Common Criteria Evaluation and
Validation Scheme (CCEVS) and the conclusions of the testing laboratory in the ETR are consistent with
the evidence provided.
The Validation team monitored the activities of the evaluation team, provided guidance on technical
issues and evaluation processes, and reviewed the individual work units documented in the ETR and the
Assurance Activities Report (AAR). The Validation team found the evaluation demonstrated the product
satisfies all of the Security Functional Requirements (SFRs) and Security Assurance Requirements (SARs)
specified in the ST. The conclusions of the testing laboratory in the ETR are consistent with the evidence
produced. Therefore, the Validation team concludes that the testing laboratory's findings are accurate,
the conclusions justified, and the conformance results are correct.
The technical information included in this report was obtained from the VMware Horizon Agent 8 2209
(Horizon 8.7) Security Target, Version 1.0, 17 May 2023, and analysis performed by the Validation team.

3 TOE Architecture
The Horizon Agent TOE consists of the Horizon Agent application. The TOE has both Windows and Linux
platform versions. The Windows application consists of C, C++, and Java code, and the Linux application
consist of C, C++, Java, Python, JavaScript, and shell code. Third-party components used by the TOE (as
specified by Appendix A.2 in the Security Target) are linked into the TOE binaries or run as a system service,
depending on the component.
3.1 Physical Boundary
The VMware Horizon Agent 8 application is a server application that that runs on virtual servers in the
enterprise environment and is responsible for serving content on the system it runs on to an authorized
Horizon Client accessing it through the virtual desktop.
The VMware Horizon Agent 8 application is part of the VMware Horizon suite of applications consisting
of Horizon Client applications, Horizon Agent applications, and Horizon Connection Server(s). A VMware
Horizon deployment typically includes one or more instances of the VMware Unified Access Gateway
(UAG) as well. Figure 1 shows the TOE in a sample deployment with other VMware Horizon applications
and the UAG in its operational environment.

Page 6 of 21
The following network ports must be open for the TOE to function:
• TCP/22443 (for Blast protocol connectivity to Horizon Client via UAG)
The TOE’s operational environment includes the following:
• Other VMware Horizon components (at least one each of Horizon Connection Server and
Horizon Client).
• Network access between “outer” and “protected” networks mediated through VMware UAG.
• Platform (hardware and software) on which the TOE is hosted.
o The TOE is capable of running on a general-purpose Windows or Linux operating system
on standard consumer-grade hardware. For the evaluated configuration, the TOE was
tested on the following environments:
▪ Windows platform:
• Windows Server 2019 and Windows 10, both virtualized on VMware
ESXi 7.0
• Platform configured into FIPS-compliant mode of operation
▪ Linux platform:
• RHEL 8, virtualized on VMware ESXi 7.0
• Platform configured into FIPS-compliant mode of operation
o Each tested configuration included an Intel Xeon 6230R (Cascade Lake) processor.
• VMware VM Encryption is required for the TOE platform to ensure adequate data-at-rest
protection.
• Authentication server (Active Directory) – optional for configuration.
The TOE has multiple editions with different features that are activated by licensing. The security
functionality claimed within the TOE boundary is not affected by which license is used. The highest tier
edition (Enterprise) was used for the tested configuration.

4 Security Policy
The TOE enforces the following security policies as described in the ST.
4.1 Cryptographic Support
The TOE makes use of cryptography to protect data at rest and in transit.
For data at rest, the Windows platform version of the TOE relies on its operational environment to control
access to stored credential data stored as certificates. All other credential data for both the Windows and
Linux platform versions are protected by TSF-provided cryptographic functions.
For protection of sensitive data in transit, the TOE implements TLS/HTTPS as a server. The TOE implements
all cryptography used for these functions using its own implementation of OpenSSL with CAVP validated
algorithms. The TOE also implements cryptography through its own implementation Bouncy Castle BC-
FJA. This is used to decrypt and encrypt data that is transmitted between the environmental Connection
Server and the TOE. The TOE’s DRBG is seeded using entropy from the underlying OS platform.
4.2 User Data Protection
The TOE relies on volume encryption via VMware VM Encryption to protect sensitive data at rest in
addition to the mechanisms described in section 4.1 above that are used to protect credential data at rest.
The TOE relies on the network connectivity of its host OS platform. The TOE can also access the system
clipboard, audio/video capture devices, and file system resources.
4.3 Security Management
The TOE itself and the configuration settings it uses are stored in locations recommended by the platform
vendor. The TOE is launched by an authenticated OS user and runs in the session context of that user;
there is no interface to the TSF to act as an administrator through separate authentication. Changes to
the product configuration are initiated from the Operational Environment.
4.4 Privacy
The TOE does not have a mechanism to retrieve or transmit personally identifiable information (PII) of
any individuals.
4.5 Protection of the TSF
The TOE enforces various mechanisms to prevent itself from being used as an attack vector to its host OS
platform. The TOE implements address space layout randomization (ASLR), does not allocate any memory
with both write and execute permissions, does not write user-modifiable files to directories that contain
executable files, is compiled using stack overflow protection, and is compatible with the security features
of its host OS platform.
The TOE contains libraries and invokes system APIs that are well-known and explicitly identified.
The TOE has a mechanism to determine its current software version. Software updates to the TOE can be
acquired through the application itself or by leveraging its OS platform, depending on the platform version
of the TOE. All updates are digitally signed to guarantee their authenticity and integrity.
4.6 Trusted Path/Channels
The TOE encrypts sensitive data in transit between itself and its operational environment using TLS/HTTPS.

5 Assumptions and Clarification of Scope
5.1 Assumptions
The Security Problem Definition, including the assumptions, may be found in the following documents:
• Protection Profile for Application Software, Version 1.4, 07 October 2021
That information has not been reproduced here and PP_APP_V1.4 should be consulted if there is interest
in that material.
As a functional package, the TLS Package does not contain a Security Problem Definition. The TOE’s use
of TLS is intended to mitigate the T.NETWORK_ATTACK and T.NETWORK_EAVESDROP threats defined by
PP_APP_V1.4.
5.2 Clarification of Scope
The scope of this evaluation was limited to the functionality and assurances covered in the
PP_APP_V1.4/FP_TLS_V1.1 as described for this TOE in the ST. Other functionality included in the product
was not assessed as part of this evaluation. All other functionality provided by the devices needs to be
assessed separately, and no further conclusions can be drawn about their effectiveness.
All evaluations (and all products) have limitations, as well as potential misconceptions that need clarifying.
This text covers some of the more important limitations and clarifications of this evaluation. Note that:
• As with any evaluation, this evaluation shows only that the evaluated configuration meets the
security claims made, with a certain level of assurance, achieved through performance by the
evaluation team of the evaluation activities specified in the following documents:
o Protection Profile for Application Software, Version 1.4, 7 October 2021 ([5])
o Functional Package for Transport Layer Security (TLS), Version 1.1, February 12, 2019 (TLS
Package)
• This evaluation covers only the specific software distribution and version identified in this
document and referenced in the VMware Horizon Agent 8 2209 (Horizon 8.7) Security Target,
Version 1.0, 17 May 2023, and not any earlier or later versions released or in process.
• Apart from the Admin Guides identified in Section 6, additional customer documentation for the
specific software version and platform versions was not included in the scope of the evaluation
and therefore should not be relied upon when configuring or operating the device as evaluated.
• This evaluation did not specifically search for, nor attempt to exploit, vulnerabilities that were not
“obvious” or vulnerabilities to objectives not claimed in the ST. The CEM defines an “obvious”
vulnerability as one that is easily exploited with a minimum of understanding of the TOE, technical
sophistication and resources.
• The functionality evaluated is scoped exclusively to the security functional requirements specified
in the PP_APP_V1.4/FP_TLS_V1.1 and applicable Technical Decisions. Any additional security
related functional capabilities included in the product were not covered by this evaluation. In
particular, the functionality mentioned in Section 8.2 of this document is excluded from the scope
of the evaluation.

8 TOE Evaluated Configuration
8.1 Evaluated Configuration
The TOE is the VMware Horizon Agent 8 2209 (Horizon 8.7), evaluated on the following host platforms:
• Windows platform:
o Windows Server 2019 and Windows 10, both virtualized on VMware ESXi 7.0
o Platform configured into FIPS-compliant mode of operation
• Linux platform:
o RHEL 8, virtualized on VMware ESXi 7.0
o Platform configured into FIPS-compliant mode of operation
Each tested configuration included an Intel Xeon 6230R (Cascade Lake) processor.
8.2 Excluded Functionality
The TOE has the following logical exclusions:
• Tunnel Channel – The Windows platform version of the Horizon Agent has a separate tunnel
channel that allows for communications of Microsoft RDP and Windows Media MMR through
HTTPS. This channel also allows a USB device connected to a remote Horizon Client system to be
accessible by the TOE platform as if it was plugged in to the remote device (USB redirection),
and it allows for the Horizon Client system’s file system to be similarly accessible on the virtual
desktop (Client Drive Redirection, or CDR). In the evaluated configuration, the communications
that use the tunnel channel are configured to use Blast instead.
• PcoIP – The Windows platform version of the Horizon Agent supports PC over IP (PcoIP) for
remote communications with Horizon Clients. In the evaluated configuration, this is disabled
and Blast is used instead (the Linux platform version only supports Blast).

9 Results of the Evaluation
The results of the evaluation of the TOE against its target assurance requirements are generally described
in this section and are presented in detail in the proprietary Evaluation Technical Report for VMware
Horizon Agent 8 2209 (Horizon 8.7). The reader of this VR can assume that all assurance activities and
work units received passing verdicts.
A verdict for an assurance component is determined by the resulting verdicts assigned to the
corresponding evaluator action elements. The evaluation was conducted based upon CC version 3.1,
revision, and the specific evaluation activities specified in:
• Protection Profile for Application Software, Version 1.4, 7 October 2021
• Functional Package for Transport Layer Security (TLS), Version 1.1, February 12, 2019
The evaluation determined the TOE satisfies the conformance claims made in the VMware Horizon Agent 8 2209
(Horizon 8.7) Security Target, of Part 2 extended and Part 3 extended. The Validation team reviewed all the work of
the evaluation team and agreed with their practices and findings.
9.1 Evaluation of the Security Target (ST) (ASE)
The Evaluation team performed each TSS evaluation activity and ASE CEM work unit. The ST evaluation
ensured the ST contains an ST introduction, TOE overview, TOE description, security problem definition in
terms of threats, policies and assumptions, description of security objectives for the operational
environment, a statement of security requirements claimed to be met by the product that are consistent
with the claimed Protection Profile, and security function descriptions that satisfy the requirements.
The Validation team reviewed the work of the Evaluation team and found that sufficient evidence and
justification was provided by the Evaluation team to confirm that the evaluation was conducted in
accordance with the requirements of the CEM, and that the conclusion reached by the Evaluation team
was justified.
9.2 Evaluation of the Development (ADV)
The Evaluation team performed each ADV evaluation activity and applied each ADV_FSP.1 CEM work unit.
The evaluation team assessed the evaluation evidence and found it adequate to meet the requirements
specified in the claimed Protection Profile for design evidence. The ADV evidence consists of the TSS
descriptions provided in the ST and product guidance documentation providing descriptions of the TOE
external interfaces.
The Validation team reviewed the work of the Evaluation team and found that sufficient evidence and
justification was provided by the Evaluation team to confirm that the evaluation was conducted in
accordance with the requirements of the CEM, and that the conclusion reached by the Evaluation team
was justified.
9.3 Evaluation of the Guidance Documents (AGD)
The Evaluation team performed each guidance evaluation activity and applied each AGD work unit. The
evaluation team determined the adequacy of the operational user guidance in describing how to operate
the TOE in accordance with the descriptions in the ST. The Evaluation team followed the guidance in the
TOE preparative procedures to test the installation and configuration procedures to ensure the
procedures result in the evaluated configuration. The guidance documentation was assessed during the
design and testing phases of the evaluation to ensure it was complete.

The Evaluation team performed each ALC evaluation activity and applied each ALC_CMC.1 and ALC_CMS.1
CEM work unit, to the extent possible given the evaluation evidence required by the claimed PP. The
evaluation team ensured the TOE is labeled with a unique identifier consistent with the TOE identification
in the evaluation evidence, and that the ST describes how timely security updates are made to the TOE.
The Validation team reviewed the work of the Evaluation team and found that sufficient evidence and
justification was provided by the Evaluation team to confirm that the evaluation was conducted in
accordance with the requirements of the CEM, and that the conclusion reached by the Evaluation team
was justified.
9.5 Evaluation of the Test Documentation and the Test Activity (ATE)
The Evaluation team performed each test activity and applied each ATE_IND.1 CEM work unit. The
Evaluation team ran the set of tests specified by the claimed PP and recorded the results in the Test
Report, summarized in the AAR.
The Validation team reviewed the work of the Evaluation team and found that sufficient evidence and
justification was provided by the Evaluation team to confirm that the evaluation was conducted in
accordance with the requirements of the CEM, and that the conclusion reached by the Evaluation team
was justified.
9.6 Vulnerability Assessment Activity (AVA)
The evaluation team performed each AVA evaluation activity and applied each AVA_VAN.1 CEM work
unit. The evaluation team performed a vulnerability analysis following the processes described in the
claimed PP. This comprised a search of public vulnerability databases.
The evaluation team performed a search of the National Vulnerability Database (https://nvd.nist.gov/).
Searches were performed on 30 March 2023, 16 May 2023 and 20 June 2023 using the following search
terms:
• VMware Horizon
• Horizon Client
• Horizon Agent
• Horizon connection server
• VMware Photon
• VMware's BC-FJA (Bouncy Castle FIPS Java API) 1.0.2.3
• VMware's OpenSSL FIPS Object Module 2.0.20-vmw
• Third Party Libraries identified in Section A.2 of the Security Target
The Evaluation team determined that that no residual vulnerabilities exist that are exploitable by attackers
with Basic Attack Potential.

met, sufficient to satisfy the assurance activities specified in the claimed PP. Additionally, the Evaluation
team’s testing also demonstrated the accuracy of the claims in the ST.
The Validation team’s assessment of the evidence provided by the Evaluation team is that it demonstrates
that the Evaluation team followed the procedures defined in the CEM, and correctly verified that the
product meets the claims in the ST.

10 Validator Comments/Recommendations
The Validation team suggests that the consumer pay particular attention to the evaluated configuration
of the TOE. As stated in the Clarification of Scope, the evaluated functionality is scoped exclusively to the
SFRs specified in the Security Target, and the only evaluated functionality was that which was described
by the SFRs claimed in the Security Target. All other functionality provided by the TOE needs to be
assessed separately and no further conclusions can be drawn about its effectiveness.
The Validation team notes that the evaluated configuration is dependent upon the TOE being configured
per the evaluated configuration instructions in VMware Horizon Agent 8 2209 (Horizon 8.7) Common
Criteria (CC) Evaluated Configuration Guide Version 1.0, May 17, 2023. Of note is that the TOE does not
have a management interface; configuration of the TOE must be performed by a different VMware
component or by manipulating files in the underlying operating system. As noted in Section 6, consumers
are encouraged to download the configuration guides from the NIAP website to ensure the device is
configured as evaluated. No versions of the TOE and software, either earlier or later were evaluated.
Any additional customer documentation, not listed in Section 6, provided with the product, or that which
may be available online, was not included in the scope of the evaluation and therefore should not be
relied upon to configure or operate the TOE as evaluated.
