1 Executive Summary
This report documents the assessment of the National Information Assurance Partnership
(NIAP) validation team of the evaluation of Samsung Galaxy S7 on Android 6 solution
provided by Samsung Electronics Co., Ltd. It presents the evaluation results, their
justifications, and the conformance results. This Validation Report is not an endorsement
of the Target of Evaluation by any agency of the U.S. government, and no warranty is
either expressed or implied.
The evaluation was performed by the Gossamer Security Solutions (Gossamer) Common
Criteria Testing Laboratory (CCTL) in Catonsville, MD, United States of America, and
was completed in May 2016. The information in this report is largely derived from the
Evaluation Technical Report (ETR) and associated test reports, all written by Gossamer
Security Solutions. The evaluation determined that the product is both Common Criteria
Part 2 Extended and Part 3 Conformant.
The Target of Evaluation (TOE) is the Samsung Galaxy S7 on Android 6.
The Target of Evaluation (TOE) identified in this Validation Report has been evaluated at a
NIAP approved Common Criteria Testing Laboratory using the Common Methodology for
IT Security Evaluation (Version 3.1, Rev 4) for conformance to the Common Criteria for
IT Security Evaluation (Version 3.1, Rev 4). This Validation Report applies only to the
specific version of the TOE as evaluated. The evaluation has been conducted in
accordance with the provisions of the NIAP Common Criteria Evaluation and Validation
Scheme and the conclusions of the testing laboratory in the evaluation technical report 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 and
successive versions of the ETR. The validation team found that the evaluation showed that
the product satisfies all of the functional requirements and assurance requirements stated in
the Security Target (ST). Therefore the validation team concludes that the testing
laboratory’s findings are accurate, the conclusions justified, and the conformance results
are correct. The conclusions of the testing laboratory in the evaluation technical report are
consistent with the evidence produced.
The technical information included in this report was obtained from the Samsung
Electronics Co., Ltd. Samsung Galaxy S7 on Android 6 (MDFPP20) Security Target,
Version 0.6, May 10, 2016 and analysis performed by the Validation Team.

3 Architectural Information
Note: The following architectural description is based on the description presented in the
Security Target.
Samsung Galaxy S7 on Android 6 Validation Report Version 0.3, May 3, 2016

The TOE is a mobile operating system based on Android 6.0.1 with modifications made to
increase the level of security provided to end users and enterprises. The TOE is intended to
be used as part of an enterprise messaging solution providing mobile staff with enterprise
connectivity.
The TOE includes a Common Criteria mode (or “CC mode”) that an administrator can
invoke through the use of a Mobile Device Management System (MDM) or through a
dedicated administrative application (see the Guidance for instructions to obtain the
application). The TOE must meet the following prerequisites in order for an administrator
to transition the TOE to CC mode.
 Require a screen lock password (swipe, PIN, pattern, or facial recognition screen
locks are not allowed).
 The maximum password failure retry policy should be less than or equal to ten.
 Device encryption must be enabled or a screen lock password required to decrypt
data on boot.
 Revocation checking must be enabled.
 External storage must be encrypted.
 Password recovery policy must not be enabled.
 Password history length must not be set.
When CC mode has been enabled, the TOE behaves as follows.
 The TOE sets the system wide Android CC mode property to “Enabled” if all the
prerequisites have been met.
 The TOE performs power-on self-tests.
 The TOE performs secure boot integrity checking of the kernel and key system
executables.
 The TOE prevents loading of custom firmware/kernels and requires all updates
occur through FOTA (Samsung’s Firmware Over The Air firmware update method)
 The TOE uses CAVP approved cryptographic ciphers when joining and
communicating with wireless networks.
 The TOE utilizes CAVP approved cryptographic ciphers for TLS.
 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. 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 container created (and to create a
KNOX container, one must purchase an additional license). Thus, the evaluation includes
several KNOX-specific claims that apply to a KNOX container when created.
3.1 TOE Evaluated Platforms
This evaluation tested the following Galaxy S7 devices:

3.2 TOE Architecture
The TOE combines with a Mobile Device Management solution 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 reduce the risks that can be introduced through a Bring-Your-Own-
Device (BYOD) model.
Data on the TOE is protected through the implementation of Samsung On-Device
Encryption (ODE) which 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 Enterprise Software Development Kit (SDK) builds on top of the existing
Android security model by expanding the current set of security configuration of options to
more than 390 configurable policies and including additional security functionality such as
application whitelisting and blacklisting.
KNOX provides the ability to enhance the BYOD model by creating a separate container
for the Enterprise. Within this container, the Enterprise can provision separate applications
and ensure they are kept separate from anything the user may do outside the KNOX
container. The Enterprise can use policy controls to manage the device as a whole or the
KNOX container specifically, as needed by the organization.
3.3 Physical Boundaries
The TOE is a multi-user operating system based on Android (6.0.1) that incorporates the
Samsung Enterprise 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
is used as a mobile device within an enterprise environment where the configuration of the
device is managed through a compliant device management solution.
Samsung Galaxy S7 on Android 6 Validation Report Version 0.3, May 3, 2016

The TOE communicates and interacts with 802.11-2012 Access Points and mobile data
networks to establish network connectivity, and the through that connectivity interacts with
MDM servers that allow administrative control of the TOE.
4 Security Policy
This section summaries 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 is designed to be able to generate 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 a cryptographic module with CAVP certified algorithms for a wide
range of cryptographic functions including: 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, IPsec, and HTTPS and also to encrypt the
media (including the generation and protection of data, right, 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 is designed to control access to system services by hosted applications, including
protection of the Trust Anchor Database. Additionally, the TOE is designed to protect 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 container enhances the security
of user data by providing an additional layer of separation between apps and data while the
device is in use.
Samsung Galaxy S7 on Android 6 Validation Report Version 0.3, May 3, 2016
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 (i.e.,
Password Authentication Factor) must be correctly entered to unlock the TOE. Also, even
when the TOE is unlocked the password must be re-entered to change the password.
Passwords are obscured when entered so they cannot be read from the TOE's display and
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 cases 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 X509v3 and validate
certificates for EAP-TLS, TLS and IPsec exchanges.
4.5 Security management
The TOE provides all the interfaces necessary to manage the security functions 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 designed 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 is also designed to protect itself from modification
by applications as well as to isolate 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 of the 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 802.11-2012, 802.1X, EAP-TLS, TLS 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
Protection Profile For Mobile Device Fundamentals, Version 2, 17 September 2014
(MDFPP). That information has not been reproduced here and the MDFPP should be
consulted if there is interest in that material.
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
performed by the evaluation team).
 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.
 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 MDFPP and applicable Technical Decisions. Any
additional security related functional capabilities of the TOE were not covered by
this evaluation.
7 Documentation
The following documentation was used as evidence for the evaluation of the Samsung
Galaxy S7:

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.
Furthermore, the evaluation includes several KNOX-specific claims that apply to a KNOX
container when created, which requires purchase of an additional license.
