3 Architectural Information
Note: The following architectural description is based on the description presented in the
Security Target.
The TOE is a mobile device based on Android 9 with a built-in IPsec VPN client and
modifications made to increase the level of security provided to end users and enterprises.
The TOE is intended for use as part of an enterprise mobility solution providing mobile
staff with enterprise connectivity.
The TOE includes a Common Criteria mode (or “CC mode”) that an administrator can
invoke using an MDM. The TOE must meet the following prerequisites in order for an
administrator to transition the TOE to and remain in the CC configuration.
 Require a boot and device lock password (swipe, PIN, pattern, accessibility (direction),
screen locks are not allowed). Acceptable biometrics vary with the device for the
device lock.
 The maximum password failure retry policy should be less than or equal to 30.
 A screen lock password required to decrypt data on boot.
 Revocation checking must be enabled.
 External storage must be encrypted.
 Password (non-container) recovery policy and password history must not be enabled.
 When CC mode has been enabled, the TOE behaves as follows:
o The TOE sets the system wide Android CC mode property to be enabled.
o The TOE prevents loading of custom firmware/kernels and requires all
updates occur through FOTA.
o The TOE utilizes CAVP approved cryptographic ciphers for TLS.
o The TOE ensures FOTA updates utilize 2048-bit PKCS #1 RSA-PSS
formatted signatures (with SHA-512 hashing).
The TOE includes a containerization capability, Knox Workspace container, which is part
of the Knox Platform. This container provides a way to segment applications and data into
two separate areas on the device, such as a personal area and a work area, each with its own
separate apps, data and security policies. For this effort, the TOE was evaluated both
without and with a Knox Workspace container created. Thus, the evaluation includes
several Knox-specific claims that apply to a Knox Workspace container when created.

3.2 TOE Architecture
The TOE combines with a Mobile Device Management solution (note that this evaluation
does not include an MDM agent nor server) that enables the Enterprise to watch, control
and administer all deployed mobile devices, across multiple mobile service providers as
well as facilitate secure communications through a VPN. This partnership provides a secure
mobile environment that can be managed and controlled by the environment and reduces
the risks that can be introduced through a Bring-Your-Own-Device (BYOD) model which
can be extended to Corporate-Owned-Personally-Enabled (COPE) or other corporate-
owned deployments.
Data on the TOE is protected through the implementation of Samsung On-Device
Encryption (ODE) or File-Based Encryption (FBE) (depending on the device see the
Security Target for a list of devices and which DAR encryption is used) that utilizes a
CAVP certified cryptographic algorithms to encrypt device storage. This functionality is
combined with a number of on-device policies including local wipe, remote wipe,
password complexity, automatic lock and privileged access to security configurations to
prevent unauthorized access to the device and stored data.
The Samsung Knox Software Development Kit (SDK) builds on top of the existing
Android security model by expanding the current set of security configuration options to
more than 600 configurable policies and including additional security functionality such as
application whitelisting and blacklisting.
The Knox Platform for Enterprise provides a set of flexible deployment options for Work
environments, including the ability to enhance the BYOD or COPE models by creating a
separate container for the Enterprise (the Workspace). Within the Knox Workspace, the
Enterprise can provision separate applications and ensure they are kept separate from
anything the user may do outside the Knox Workspace. The Enterprise can use policy
controls to manage a Work environment on the device as a whole or within the Knox
Workspace container specifically, as needed by the organization.
3.3 Physical Boundaries
The TOE is a multi-user mobile device based on Android 9 that incorporates the Samsung
Knox SDK. The TOE does not include the user applications that run on top of the operating
system, but does include controls that limit application behavior. The TOE includes an
IPsec VPN client integrated into the firmware (as opposed to a downloadable application).
Within an Enterprise environment, the Enterprise can manage the configuration of the
mobile device, including the VPN client, through a compliant device management solution.
Samsung Galaxy Devices on Android 9-Fall Validation Report Version 0.4, November 4, 2019

The TOE communicates and interacts with 802.11-2012 Access Points and mobile data
networks to establish network connectivity.
4 Security Policy
This section summarizes the security functionality of the TOE:
1. Security audit
2. Cryptographic support
3. User data protection
4. Identification and authentication
5. Security management
6. Protection of the TSF
7. TOE access
8. Trusted path/channels
4.1 Security audit
The TOE generates logs for a range of security relevant events. The TOE stores the logs
locally so they can be accessed by an administrator or they can be exported to an MDM.
4.2 Cryptographic support
The TOE includes multiple cryptographic libraries with CAVP certified algorithms for a
wide range of cryptographic functions including the following: asymmetric key generation
and establishment, symmetric key generation, encryption/decryption, cryptographic
hashing and keyed-hash message authentication. These functions are supported with
suitable random bit generation, key derivation, salt generation, initialization vector
generation, secure key storage, and key and protected data destruction. These primitive
cryptographic functions are used to implement security protocols such as TLS, EAP-TLS,
IPsec, and HTTPS and to encrypt the media (including the generation and protection of
data and key encryption keys) used by the TOE. Many of these cryptographic functions are
also accessible as services to applications running on the TOE.
4.3 User data protection
The TOE controls access to system services by hosted applications, including protection of
the Trust Anchor Database. Additionally, the TOE protects user and other sensitive data
using encryption so that even if a device is physically lost, the data remains protected. The
functionality provided by a Knox Workspace container enhances the security of user data
by providing an additional layer of separation between different categories of apps and data
while the device is in use. The TOE ensures that residual information is protected from
potential reuse in accessible objects such as network packets.
Samsung Galaxy Devices on Android 9-Fall Validation Report Version 0.4, November 4, 2019
7
4.4 Identification and authentication
The TOE supports a number of features related to identification and authentication. From a
user perspective, except for making phone calls to an emergency number, a password or
Biometric Authentication Factor (BAF) must be correctly entered to unlock the TOE. In
addition, even when the TOE is unlocked the password must be re-entered to change the
password or re-enroll the biometric template. Passwords are obscured when entered so they
cannot be read from the TOE's display, the frequency of entering passwords is limited and
when a configured number of failures occurs, the TOE will be wiped to protect its contents.
Passwords can be constructed using upper- and lower-case characters, numbers, and special
characters and passwords between 4 and 16 characters are supported.
The TOE can also serve as an 802.1X supplicant and can use X.509v3 and validate
certificates for EAP-TLS, TLS and IPsec exchanges. The TOE can also act as a client or
server in an authenticated Bluetooth pairing. In addition to storing X.509 certificates used
for IPsec connections, the TOE can also securely store pre-shared keys for VPN
connections.
4.5 Security management
The TOE provides all the interfaces necessary to manage the security functions (including
the VPN client) identified throughout this Security Target as well as other functions
commonly found in mobile devices. Many of the available functions are available to users
of the TOE while many are restricted to administrators operating through a Mobile Device
Management solution once the TOE has been enrolled. Once the TOE has been enrolled
and then un-enrolled, it removes all MDM policies and disables CC mode.
4.6 Protection of the TSF
The TOE implements a number of features to protect itself to ensure the reliability and
integrity of its security features. It protects particularly sensitive data such as cryptographic
keys so that they are not accessible or exportable. It also provides its own timing
mechanism to ensure that reliable time information is available (e.g., for log
accountability). It enforces read, write, and execute memory page protections, uses address
space layout randomization, and stack-based buffer overflow protections to minimize the
potential to exploit application flaws. It also protects itself from modification by
applications as well as isolates the address spaces of applications from one another to
protect those applications.
The TOE includes functions to perform self-tests and software/firmware integrity checking
so that it might detect when it is failing or may be corrupt. If any self-tests fail, the TOE
will not go into an operational mode. It also includes mechanisms (i.e., verification of the
digital signature of each new image) so that the TOE itself can be updated while ensuring
that the updates will not introduce malicious or other unexpected changes in the TOE.
Digital signature checking also extends to verifying applications prior to their installation.

4.7 TOE access
The TOE can be locked, obscuring its display, by the user or after a configured interval of
inactivity. The TOE also has the capability to display an advisory message (banner) when
users unlock the TOE for use.
The TOE is also able to attempt to connect to wireless networks as configured.
4.8 Trusted path/channels
The TOE supports the use of IEEE 802.11-2012, 802.1X, EAP-TLS, TLS, HTTPS and
IPsec to secure communications channels between itself and other trusted network devices.
5 Assumptions
The Security Problem Definition, including the assumptions, may be found in the following
documents:
 Protection Profile for Mobile Device Fundamentals, Version 3.1, 16 June 2017,
General Purpose Operating Systems Protection Profile/Mobile Device
Fundamentals Protection Profile Extended Package (EP) Wireless Local Area
Network (WLAN) Clients, Version 1.0, 08 February 2016 and PP-Module for
Virtual Private Network (VPN) Clients, Version 2.1, 05 October 2017
That information has not been reproduced here and the MDFPP31/WLANCEP10/VPNC21
should be consulted if there is interest in that material.
The scope of this evaluation was limited to the functionality and assurances covered in the
MDFPP31/WLANCEP10/VPNC21 as described for this TOE in the Security Target. 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.
6 Clarification of Scope
All evaluations (and all products) have limitations, as well as potential misconceptions that
need clarification. This text covers some of the more important limitations and
clarifications of this evaluation. Note that:
 As with any evaluation, this evaluation only shows that the evaluated configuration
meets the security claims made with a certain level of assurance (the assurance
activities specified in the Mobile Device Fundamentals Protection Profile and
General Purpose Operating Systems Protection Profile/Mobile Device
Fundamentals Protection Profile Extended Package (EP) Wireless Local Area
Network (WLAN) Clients and Virtual Private Network (VPN) Clients PP-Module
and performed by the evaluation team).
Samsung Galaxy Devices on Android 9-Fall Validation Report Version 0.4, November 4, 2019

 This evaluation covers only the specific device models and software as identified in
this document, and not any earlier or later versions released or in process.
 Apart from the VPN and MDF Admin Guides, additional customer documentation
for the specific mobile device models was not included in the scope of the
evaluation and therefore should not to 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 MDFPP31/WLANCEP10/VPNC21 and applicable
Technical Decisions. Any additional security related functional capabilities of the
TOE were not covered by this evaluation.
 While an MDM can be used in configuring the TOE into CC Mode, an MDM agent
and server were not included and thus MDM functionality was not evaluated.
 The security functionality provided by the Knox Workspace container is limited to
the Knox-specific claims made in this evaluation. All other functionality provided
by the container is out of scope.
7 Documentation
The following documents were available with the TOE for evaluation:
 Samsung Android 9 on Galaxy Devices Administrator Guide, version 5.2, October
16, 2019
 Samsung VPN Client on Galaxy Devices Administrator Guide, version 5.2, August
15, 2019
Any additional customer documentation provided with the product, or that is available
online was not included in the scope of the evaluation and therefore should not to be relied
upon when configuring or operating the device as evaluated.
To use the product in the evaluated configuration, the product must be configured as
specified in the Guidance Documentation listed above. Consumers are encouraged to
download the configuration guides from the NIAP website to ensure the device is
configured as evaluated.

The validators 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.
10.5 Evaluation of the Test Documentation and the Test Activity (ATE)
The evaluation team applied each ATE CEM work unit. The evaluation team ran the set of
tests specified by the assurance activities in the MDFPP31/WLANCEP10/VPNC21 and
recorded the results in a Test Report, summarized in the AAR.
The validators 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.
10.6 Vulnerability Assessment Activity (VAN)
The evaluation team applied each AVA CEM work unit. The vulnerability analysis is in the
Detailed Test Report (DTR) prepared by the evaluator. The vulnerability analysis includes
a public search for vulnerabilities. The public search for vulnerabilities conducted on
October 17, 2019 did not uncover any residual vulnerability.

The evaluator searched the National Vulnerability Database
(https://web.nvd.nist.gov/view/vuln/search) and Vulnerability Notes Database
(http://www.kb.cert.org/vuls/) with the following search terms: "Samsung Tab Active2",
"Knox", "Android", "BoringSSL", "strongswan", "charon", "Samsung Galaxy Note10", and
"Samsung Galaxy Tab S3".
The validators 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.
10.7 Summary of Evaluation Results
The evaluation team’s assessment of the evaluation evidence demonstrates that the claims
in the ST are met. 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.
11 Validator Comments/Recommendations
The evaluated configuration requires that software updates to the TOE be restricted to
FOTA. The evaluators were unable to directly exercise this mechanism since it would have
involved placing invalid updates on the live public servers that are currently in use by
present customers. Hence, the evaluators had to take the products out of the evaluated
configuration to test the update features.
The validators suggest that the consumer pay particular attention to the evaluated
configuration of the device(s). The functionality evaluated is scoped exclusively to the
security functional requirements specified in the Security Target, and only the functionality
implemented by the SFR’s within the Security Target was evaluated. All other functionality
provided by the devices, to include software that was not part of the evaluated
configuration, needs to be assessed separately and no further conclusions can be drawn
about their effectiveness.
The validators encourage the consumers of these products to understand the relationship
between the products and any functionality that may be provided via Mobile Device
Management (MDM), Enterprise Device Management (EDM), and Enterprise Mobility
Management (EMM) solutions (hereafter collectively referred to as MDM solutions). This
evaluation neither covers, nor endorses, the use of any particular MDM solution; only the
MDM-like interfaces of the products were exercised as part of the evaluation. In practice,
the Samsung EDMapp and STIGtool are not available, though its settings could be
managed via a suitable MDM solution and corresponding agent. Samsung does not intend
to make the EDMApp and STIGtool available; however, the APIs used by these tools have
been made available by Samsung. Per Section 2.3.2 of the Admin Guide, “this EDM should
Samsung Galaxy Devices on Android 9-Fall Validation Report Version 0.4, November 4, 2019
14
support the Samsung Knox APIs to enable the capabilities documented in this guide.”
Further, the Admin Guide states that the “Common Criteria Configuration section provides
the specific information about the Knox APIs that are necessary to support this
configuration….” Because the EDMApp and STIGtool apps are not available, a compatible
MDM solution is required for the TOE to be placed in CC Mode, which in turn, places it in
the evaluated configuration.

evaluations.
 Conformance. The ability to demonstrate in an unambiguous way that a given
implementation is correct with respect to the formal model.
 Evaluation. The assessment of an IT product against the Common Criteria using the
Common Criteria Evaluation Methodology to determine whether or not the claims
made are justified; or the assessment of a protection profile against the Common
Criteria using the Common Evaluation Methodology to determine if the Profile is
complete, consistent, technically sound and hence suitable for use as a statement of
requirements for one or more TOEs that may be evaluated.
 Evaluation Evidence. Any tangible resource (information) required from the sponsor
or developer by the evaluator to perform one or more evaluation activities.
 Feature. Part of a product that is either included with the product or can be ordered
separately.
 Target of Evaluation (TOE). A group of IT products configured as an IT system, or
an IT product, and associated documentation that is the subject of a security evaluation
under the CC.
