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 March 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) are the LG G5, V10, and G4 Smartphones. 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 versions of the TOE that were evaluated. The evaluation was 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 Gossamer Security Solutions evaluation team concluded that the Common Criteria requirements are for Evaluation Assurance Level (EAL) 1. The technical information included in this report was obtained from the LG Electronics Inc.

The TOE is a mobile device designed to support enterprises and individual users alike. Based upon Android 6.0 and improved by LG, the TOE provides wireless connectivity and provides an execution environment for mobile applications. The TOE allows basic telephony features (make and receive phone calls, send and receive SMS/MMS messages) as well as advanced network connectivity (allowing connections to both IEEE 802.11 Wi-Fi and 2G/3G/4G LTE mobile data networks). The TOE supports using client certificates to connect to access points offering WPA2 networks with IEEE 802.1x/EAP-TLS, or alternatively connecting to cellular base stations when utilizing mobile data. The TOE offers mobile applications an Application Programming Interface (API) including that provided by the Android framework and extensions to the MDM API by LG. The TOE provides users installing an application the option to either approve or reject an application based upon the API access that the application requires. The TOE also provides users with the ability to protect Data-At-Rest with AES encryption, including all user and mobile application data stored in the user’s data partition. The TOE affords protection to all user and application cryptographic keys stored in the TOE. Moreover, the TOE provides users the ability to AES encrypt data and files stored on an SD Card inserted into the device. Finally, the TOE can interact with a suitable Mobile Device Management solution to allow for enterprise control of the configuration and operation of the devices to ensure adherence to enterprise-wide policies. Note that in order to utilize the TOE in its evaluated configuration, the TOE must be configured into its Common Criteria Mode. 3.1 TOE Evaluated Platforms The evaluated configuration for the G5, V10, and G4 Smartphones comes in the following different carrier versions: Product Carrier Security SW Version OS version Build number WFA Cert# LG G5 H820 AT&T MDF v2.0 Release 2 Android 6.0.1 MMB29M 63786 LG G5 VS987 Verizon MDF v2.0 Release 2 Android 6.0.1 MMB29M 63656 LG G5 LS992 Sprint MDF v2.0 Release 2 Android 6.0.1 MMB29M 63797 LG G5 H830 T-Mobile MDF v2.0 Release 2 Android 6.0.1 MMB29M 63768 LG V10 H900 AT&T MDF v2.0 Release 2 Android 6.0 MRA58K 61545 LG V10 VS990 Verizon MDF v2.0 Release 2 Android 6.0 MRA58K 61481 LG V10 H901 T-Mobile MDF v2.0 Release 2 Android 6.0 MRA58K 61546 LG G4 H810 AT&T MDF v2.0 Release 2 Android 6.0 MRA58K 58690 LG G4 VS986 Verizon MDF v2.0 Release 2 Android 6.0 MRA58K 58682 LG G4 LS991 Sprint MDF v2.0 Release 2 Android 6.0 MRA58K 58680 LG G5, V10, and G4 Smartphones Validation Report Version 0.3, April 9, 2016 4 Product Carrier Security SW Version OS version Build number WFA Cert# LG G4 H811 T-Mobile MDF v2.0 Release 2 Android 6.0 MRA58K 58678 NOTE: Carrier specific versions of the evaluated product are released based upon that carrier’s own schedule, so some carriers may not have released the evaluated version of the TOE by the time this report is published. Therefore, consumers should ensure that they have the evaluated version of the product software. 3.2 Physical Boundaries The TOE’s physical boundary is the physical perimeter of its enclosure (without the rear access cover present, so that one can access and replace the device’s battery, SIM, and SD Card). 4 Security Policy This section summaries the security functionality of the TOE: 1. Cryptographic support 2. User data protection 3. Identification and authentication 4. Security Management 5. Protection of the TSF 6. TOE access 7. Trusted path/channels 4.1 Cryptographic support The TOE includes cryptographic modules with CAVP certified algorithms for a 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 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 and HTTPS and also to encrypt Data-At-Rest (including the generation and protection of keys and key encryption keys) used by the TOE. Cryptographic functions are also accessible as services to applications running on the TOE. 4.2 User data protection The TOE controls access to system services by hosted applications, including protection of the Trust Anchor Database. Additionally, the TOE is designed to protect user and other data using encryption so that even if a device is physically lost, the data remains protected. The TOE supports Android for Work profiles to provide additional separation between LG G5, V10, and G4 Smartphones Validation Report Version 0.3, April 9, 2016 5 application and application data belonging to the Android for Work profile. Please see the Admin Guide for additional details regarding how to set up and use Android for Work profiles. 4.3 Identification and authentication The TOE supports 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. To change an existing password even if the TOE is unlocked, the existing password must be re-entered before the user is allowed to change that password. Passwords are obscured when entered so they cannot be read from the TOE's display. The frequency of entering passwords is limited such that when a configured number of password entry 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. Passwords up to 16 characters are supported. The TOE can also serve as an IEEE 802.1X supplicant and can use X.509v3 and validate certificates for EAP-TLS, TLS, and HTTPS exchanges. 4.4 Security management The TOE provides interfaces to manage the security functions identified throughout this Security Target as well as other functions found in mobile devices. Some functions are available to users of the TOE while others are restricted to administrators operating through a Mobile Device Management solution; if the TOE has been enrolled. Once the TOE has been enrolled and then un-enrolled, it will remove Enterprise applications, remove MDM policies, and disable CC mode. 4.5 Protection of the TSF The TOE implements mechanisms to protect itself and ensure the reliability and integrity of its security features. It protects sensitive data such as cryptographic keys so that they are not accessible or exportable. It 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, the use of address space layout randomization, and stack-based buffer overflow protections to minimize the potential to exploit application flaws. The TOE employs mechanisms to protect itself from modification by applications as well as to isolate the address spaces of applications from each other 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 enter 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 as all applications must have signatures even if self-signed. LG G5, V10, and G4 Smartphones Validation Report Version 0.3, April 9, 2016 6 4.6 TOE access The TOE can be locked, by the user or after a configured interval of inactivity thereby obscuring its display. The TOE has the capacity to display an administrator specified (using an MDM) advisory message when the user unlocks the TOE for the first use after reboot. The TOE can attempt to connect to wireless networks if so configured. 4.7 Trusted path/channels The TOE supports the use of IEEE 802.11-2012, IEEE 802.1X, and EAP-TLS to secure communications channels between itself and other trusted network devices. 5 Assumptions and Clarification of Scope The Security Problem Definition, including the assumptions, may be found in the Protection Profile For Mobile Device Fundamentals, Version 2.0, 17 September 2014 (MDFPP20). That information has not been reproduced here; the MDFPP20 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 MDFPP20 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. 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: 1. 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). 2. 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. 3. Android for Work functionality can be used to account for BYOD scenarios where personal data and Enterprise data are separated; however, it is not required for the MDF PP. Therefore, its use is out of scope and it has not been evaluated. 4. 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 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. 9.7 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. 10 Validator Comments/Recommendations 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 solutions. This evaluation does not cover, nor does it endorse, the use of any particular MDM solution and only the MDM interfaces of the products were exercised as part of the evaluation. In practice, the LG MDM is not available, though its settings could LG G5, V10, and G4 Smartphones Validation Report Version 0.3, April 9, 2016 11 be managed via a suitable MDM and corresponding agent. Alternatively, LG has developed a downloadable application that can be utilized to put the device into CC mode – MDM Test.apk. The LG Android 6 Devices (G5, V10, G4) Guidance Documentation contains instructions on how the application can be acquired. As of the conclusion of this evaluation, an administrator can send an e-mail to support-enterprise-mobility@lge.com to request the application. Note that the products must be configured into Common Criteria Mode as directed in the LG Electronics Inc. LG Android 6 Devices (G5, V10, G4) Guidance Documentation, version 0.5, Section 3.1 in order to be in the evaluated configuration. Although Android for Work was used in testing to successfully demonstrate the TOEs ability to satisfy FDP_ACF_EXT.1.2 per the DoD Annex; Android for Work is not required in the Common Criteria evaluated configuration. Over-The-Air (OTA) updates were not available during the evaluation; these are created by Google and the mobile device vendors, then distributed to the wireless carriers (Verizon, AT&T, etc), for deployment to the respective devices via the carriers network. Therefore the OTA update functionality was not tested. Users and enterprise administrators should remain cognizant of OTA updates and the update cycles offered by the carriers. 11 Annexes Not applicable 12 Security Target The Security Target is identified as: LG G5, V10, and G4 Smartphones (MDFPP20) Security Target, Version 0.7, April 8, 2016. 13 Glossary The following definitions are used throughout this document:  Common Criteria Testing Laboratory (CCTL).
