1 Executive Summary
This Validation Report (VR) documents the National Information Assurance Partnership (NIAP) assessment
of the evaluation of Hypori Virtual Mobile Infrastructure Platform 4.2.0 Client (iOS) (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.
This VR is intended to assist the end-user of this product and any security certification agent for that end-
user in determining the suitability of this Information Technology (IT) product in their environment. End-
users should review the Security Target (ST), which is where specific security claims are made, in
conjunction with this VR, which describes how those security claims were evaluated and tested and any
restrictions on the evaluated configuration. This VR applies only to the specific version and configuration
of the product as evaluated and as documented in the ST. Prospective users should carefully read the
Assumptions and Clarification of Scope in Section 5 and the Validator Comments in Section 10, where any
restrictions on the evaluated configuration are highlighted.
The evaluation was performed by Leidos Common Criteria Testing Laboratory (CCTL) in Columbia,
Maryland, USA, and was completed in March 2021. 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 demonstrates exact conformance to:
 Protection Profile for Application Software, Version 1.3, 1 March 2019 ([5])
as clarified by all applicable Technical Decisions.
The TOE is Hypori Client (iOS) 4.2.0.
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 that the evaluation showed that the product
satisfies all of the functional requirements and assurance requirements stated 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 Leidos evaluation team determined that the TOE is conformant to the claimed Protection Profile (PP)
and, when installed, configured and operated as specified in the evaluated guidance documentation,
satisfies all the security functional requirements stated in the ST ([6]).

2 Identification
The CCEVS is a joint National Security Agency (NSA) and National Institute of Standards and Technology
(NIST) effort to establish commercial facilities to perform trusted product evaluations. Under this
program, commercial testing laboratories called Common Criteria Testing Laboratories (CCTLs) use the
Common Criteria (CC) and Common Methodology for IT Security Evaluation (CEM) to conduct security
evaluations, in accordance with National Voluntary Laboratory Assessment Program (NVLAP)
accreditation.
The NIAP Validation Body assigns Validators to monitor the CCTLs to ensure quality and consistency across
evaluations. Developers of IT products desiring a security evaluation contract with a CCTL and pay a fee
for their product’s evaluation. Upon successful completion of the evaluation, the product is added to
NIAP’s Product Compliant List (PCL).
Table 1 provides information needed to completely identify the product, including:
 The TOE—the fully qualified identifier of the product as evaluated
 The ST—the unique identification of the document describing the security features, claims, and
assurances of the product
 The conformance result of the evaluation
 The PP/PP-Modules to which the product is conformant
 The organizations and individuals participating in the evaluation.

3 TOE Architecture
Note: The following architectural description is based on the description presented in the ST.
Hypori Client (iOS) 4.2.0 is a component of the Hypori Virtual Mobile Infrastructure (VMI) Platform. In the
Hypori VMI platform, end users install and run the TOE on their mobile devices to access a Hypori Virtual
Device running on a Hypori Server in the cloud. The Hypori Virtual Device on the Hypori Server contains
data and applications for the users. The TOE communicates with the Hypori Virtual Device using TLS 1.2
and brokers access between the mobile device’s sensors and the applications executing in the Hypori
Virtual Device. This concept of operation is illustrated in the following figure.
Figure 1 Hypori Client as Part of VMI Platform
The TOE comprises the Hypori Client (iOS) 4.2.0 application as defined in the Hypori Client installation
package. The TOE is an iOS-based thin client that communicates only with the Hypori Server, using TLS 1.2
(provided by the underlying iOS platform). The Hypori Server, applications running on the Hypori Server,
and any functions not specified in the ST are outside the scope of the TOE. Figure 2 shows the relationship
of the TOE to its operational environment.

Figure 2 TOE Boundary for iOS Devices
The TOE’s operational environment comprises the iOS-based mobile device on which it is installed. The
TOE is evaluated on iOS 12 and iOS 13 (with the exception of iOS 13.1, which has a known incompatibility).

4 Security Policy
The TOE enforces the following security policies as described in the ST.
Note: Much of the description of the security policy has been derived from the ST and the Final ETR.
4.1 Cryptographic Support
The TOE establishes secure communication with the Hypori Server using TLS. It uses cryptographic services
provided by the platform. The TOE stores credentials and certificates for mutual authentication in the
platform’s key chain.
4.2 User Data Protection
The TOE informs a user of hardware and software resources the TOE accesses. It uses the platform’s
permission mechanism to get a user’s approval for access as part of the installation process. The user
initiates a secure network connection to the Hypori Server using the TOE. In general, sensitive data resides
on the Hypori Server and not the TOE or TOE platform, although the TOE does store credentials as
identified above in Section 4.1.
4.3 Identification and Authentication
The TOE uses the platform’s certificate validation services to authenticate the X.509 certificate the Hypori
Server presents as part of establishing a TLS connection.
4.4 Security Management
Security management consists of setting Hypori Client configuration options. The TOE uses the platform’s
mechanisms for storing the configuration settings.
4.5 Privacy
The TOE does not transmit personally identifiable information (PII) over a network.
4.6 Protection of the TSF
The TOE uses security features and APIs that the platform provides. The TOE leverages package
management for secure installation and updates. The TOE package includes only those third-party
libraries necessary for its intended operation.
4.7 Trusted Path/Channels
The TOE invokes platform-provided functionality to encrypt all transmitted data using TLS 1.2 for all
communication with the Hypori Server.

5 Assumptions and Clarification of Scope
5.1 Assumptions
The ST references the PP to which it claims conformance for assumptions about the use of the TOE. Those
assumptions, drawn from the claimed PP, are as follows:
 The TOE relies upon a trustworthy computing platform with a reliable time clock for its execution.
This includes the underlying platform and whatever runtime environment it provides to the TOE.
 The user of the application software is not willfully negligent or hostile, and uses the software in
compliance with the applied enterprise security policy.
 The administrator of the application software is not careless, willfully negligent or hostile, and
administers the software in compliance with the applied enterprise security policy.
5.2 Clarification of Scope
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 (the evaluation activities specified in
Protection Profile for Application Software, Version 1.3, 1 March 2019 ([5]) and performed by the
evaluation team).
 This evaluation covers only the specific software distribution and version identified in this
document, and not any earlier or later versions released or in process.
 The evaluation of security functionality of the product was limited to the functionality specified
in Hypori Virtual Mobile Infrastructure Platform 4.2.0 Client (iOS) Security Target, Version 1.0, 10
February 2021 ([6]).
 The TOE consists solely of software and relies on its operational environment for supporting
security functionality, as identified in [6].
 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 TOE must be installed, configured and managed as described in the documentation
referenced in Section 6 of this VR.

6 Documentation
The vendor offers guidance documents describing the installation process for the TOE as well as guidance
for subsequent administration and use of the applicable security features. The guidance documentation
examined during the evaluation and delivered with the TOE is as follows:
 Hypori User Guide Common Criteria Configuration and Operation, Version 4.2.0 ([7])
 Hypori Virtual Mobility User Guide – iOS Client Release 4.2, v.1.1 ([8])
To use the product in the evaluated configuration, the product must be configured as specified in this
documentation.
Any additional customer documentation 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. Consumers are encouraged to download the evaluated administrative
guidance documentation from the NIAP website.

7 IT Product Testing
This section describes the testing efforts of the evaluation team. It is derived from information contained
in the following proprietary document:
 Hypori Virtual Mobile Infrastructure Platform 4.2.0 Client (iOS) Common Criteria Test Report and
Procedures, Version 1.0, 26 February 2021 ([11])
A non-proprietary description of the tests performed and their results is provided in the following
document:
 Assurance Activities Report for Hypori Virtual Mobile Infrastructure Platform 4.2.0 Client (iOS),
Version 1.0, 26 February 2021 ([10])
The purpose of the testing activity was to confirm the TOE behaves in accordance with the TOE security
functional requirements as specified in the ST for a product that claims conformance to Protection Profile
for Application Software ([5]).
The evaluation team devised a Test Plan based on the Test Activities specified in Protection Profile for
Application Software. The Test Plan described how each test activity was to be instantiated within the TOE
test environment. The evaluation team executed the tests specified in the Test Plan and documented the
results in the team test report listed above.
Independent testing took place at Leidos CCTL facilities in Columbia, Maryland, from September 2020
through February 2021.
The evaluators received the TOE in the form that customers would receive it, installed and configured the
TOE in accordance with the provided guidance, and exercised the Team Test Plan on equipment
configured in the testing laboratory.
Given the complete set of test results from the test procedures exercised by the evaluators, the testing
requirements for Protection Profile for Application Software were fulfilled.
7.1 Test Configuration
The evaluation team established a test configuration consisting of the TOE (Hypori Client (iOS) 4.2.0)
installed on each of the following iOS devices:
 Apple iPhone 8 running iOS 12.1
 Apple iPhone 8 running iOS 13.2.3.
The test configuration also included a test server used to support testing of X.509 requirements and to
perform port scans. The test server, running Ubuntu 18.04, included the following testing tools:
 OpenSSL 1.1.1
 Nmap 7.60
 Custom Leidos CCTL TLS Server and Client test tools.

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 Hypori Virtual
Mobile Infrastructure Platform 4.2.0 Client (iOS) Part 2 ([9]). 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 5 ([1], [2], [3]) and CEM version 3.1, revision 5 ([4]), and the specific evaluation activities specified
in Protection Profile for Application Software, Version 1.3, 1 March 2019 ([5]). The evaluation determined
the TOE satisfies the conformance claims made in the Hypori Virtual Mobile Infrastructure Platform 4.2.0
Client (iOS) Security Target, of Part 2 extended and Part 3 extended. The TOE satisfies the requirements
specified in:
 Protection Profile for Application Software, Version 1.3, 1 March 2019 ([5]).
The Validators 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 assurance 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.
9.2 Evaluation of the Development (ADV)
The evaluation team performed each ADV assurance 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.
9.3 Evaluation of the Guidance Documents (AGD)
The evaluation team performed each guidance assurance 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.
9.4 Evaluation of the Life Cycle Support Activities (ALC)
The evaluation team performed each ALC assurance 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 Protection
Profile. 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.

9.5 Evaluation of the Test Documentation and the Test Activity (ATE)
The evaluation team performed each test activity and applied each ATE_FUN.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.
9.6 Vulnerability Assessment Activity (AVA)
The evaluation team performed each AVA assurance 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. In accordance with NIAP Technical Decision
TD0554, the evaluation team did not need to run a virus scanner against the application files because the
TOE is an iOS application.
Searches of public vulnerability repositories were performed on 25 February 2021.
The evaluation team searched the following public vulnerability repositories.
 National Vulnerability Database (http://web.nvd.nist.gov/view/vuln/search)
 US-CERT Vulnerability Notes Database (https://www.kb.cert.org/vuls/).
The evaluation team used the following search terms in the searches of these repositories:
 Hypori
 Intelligent Waves
 Hypori Client
 Hypori iOS Client
 iOS Thin Client
 Virtual Mobile Infrastructure
 iOS Cloud Environment
 Opus Audio Codec v1.1
 Protobuf v2.5
 PLCrashReporter 1.2
 iOS-openssl v1.1e
 spice-qtk v2.2.
The results of these searches did not identify any vulnerabilities that are applicable to the TOE. The
conclusion drawn from the vulnerability analysis is that no residual vulnerabilities exist that are
exploitable by attackers with Basic Attack Potential as defined by the Certification Body in accordance
with the guidance in the CEM.
9.7 Summary of Evaluation Results
The evaluation team’s assessment of the evaluation evidence demonstrates that the claims in the ST are
met, sufficient to satisfy the assurance activities specified in the claimed Protection Profile. 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 validators suggest 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 security
functional requirements 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.
Consumers employing the TOE must follow the configuration instructions provided in the Configuration
Guidance documentation listed in Section 6 to ensure the evaluated configuration is established and
maintained.
