Title

Google Android 16 must be configured to enforce an application installation policy by specifying one or more authorized application repositories, including [selection: DODDoW-approved commercial app repository, MDM server, mobile application store].

Check text

Review managed Google Android 16 device configuration settings to determine if the mobile device has only approved application repositories (DODDoW-approved commercial app repository, EMM server, and/or mobile application store). This validation procedure is performed on both the EMM Administration Console and the managed Google Android 16 device. On the EMM console: COBO and COPE: 1. Open "Set user restrictions". 2. Verify that "Disallow install unknown sources" is toggled to "ON". 3. Verify that "Disallow installs from unknown sources globally" is toggled to "ON". On the Google Android 16 device: COBO and COPE: 1. Open Settings >> Apps >> Special app access. 2. Open "Install unknown apps". 3. Ensure the list of apps is blank, or if an app is on the list, "Disabled by admin" is listed under the app name. If the EMM console device policy is not set to allow connections to only approved application repositories, or on the managed Google Android 16 device the device policy is not set to allow connections to only approved application repositories, this is a finding.

Discussion

Forcing all applications to be installed from authorized application repositories can prevent unauthorized and malicious applications from being installed and executed on mobile devices. Allowing such installations and executions could cause a compromise of DODDoW data accessible by these unauthorized/malicious applications. SFR ID: FMT_SMF.1.1 #8

V-276856CAT IIGoogle Android 16 must be configured to enforce an application installation policy by specifying an application allowlist that restricts applications by the following characteristics: [selection: list of digital signatures, cryptographic hash values, names, application version].Discussion

Discussion

The application allowlist, in addition to controlling the installation of applications on the MD, must control user access/execution of all core and preinstalled applications, or the mobile device (MD) must provide an alternate method of restricting user access/execution to core and preinstalled applications. Core application: Any application integrated into the operating system (OS) by the OS or MD vendors. Preinstalled application: Additional noncore applications included in the OS build by the OS vendor, MD vendor, or wireless carrier. Requiring all authorized applications to be in an application allowlist prevents the execution of any applications (e.g., unauthorized, malicious) that are not part of the allowlist. Failure to configure an application allowlist properly could allow unauthorized and malicious applications to be downloaded, installed, and executed on the mobile device, causing a compromise of DODDoW data accessible by these applications. The application allowlist, in addition to controlling the installation of applications on the MD, must control user access/execution of all core applications (included in the OS by the OS vendor) and preinstalled applications (provided by the MD vendor and wireless carrier), or the MD must provide an alternate method of restricting user access/execution to core and preinstalled applications.

On the EMM console: 1. Go to the Android app catalog for managed Google Play. 2. Before selecting an app, review the app details and privacy policy to ensure the app does not include prohibited characteristics. Managed Google Play is always an allowlisted App Store.

Discussion

Requiring all authorized applications to be in an application allowlist prevents the execution of any applications (e.g., unauthorized, malicious) that are not part of the allowlist. Failure to configure an application allowlist properly could allow unauthorized and malicious applications to be downloaded, installed, and executed on the mobile device, causing a compromise of DODDoW data accessible by these applications. Applications with the listed characteristics have features that can cause the compromise of sensitive DODDoW data or have features with no known application in the DODDoW environment. Application note: The application allowlist, in addition to controlling the installation of applications on the MD, must control user access/execution of all core and preinstalled applications, or the MD must provide an alternate method of restricting user access/execution to core and preinstalled applications. Core application: Any application integrated into the operating system (OS) by the OS or MD vendors. Preinstalled application: Additional noncore applications included in the OS build by the OS vendor, MD vendor, or wireless carrier. SFR ID: FMT_SMF.1.1 #8

V-276860CAT IIGoogle Android 16 must be configured to disable trust agents.Discussion

Discussion

Trust agents allow a user to unlock a mobile device without entering a passcode when the mobile device is, for example, connected to a user-selected Bluetooth device or in a user-selected location. This technology would allow unauthorized users to have access to DODDoW sensitive data if compromised. By not permitting the use of nonpassword authentication mechanisms, users are forced to use passcodes that meet DODDoW passcode requirements. SFR ID: FMT_SMF.1.1 #22, FIA_UAU.5.1

V-276861CAT IIGoogle Android 16 must be configured to disable developer modes.Discussion

Discussion

Discussion

Before granting access to the system, the mobile operating system is required to display the DODDoW-approved system use notification message or banner that provides privacy and security notices consistent with applicable federal laws, Executive Orders, directives, policies, regulations, standards, and guidance. Required banners help ensure that DODDoW can audit and monitor the activities of mobile device users without legal restriction. System use notification messages can be displayed when individuals first access or unlock the mobile device. The banner must be implemented as a "click-through" banner at device unlock (to the extent permitted by the operating system). A "click-through" banner prevents further activity on the information system unless and until the user executes a positive action to manifest agreement by clicking on a box indicating "OK." The approved DODDoW text must be used exactly as required in the Knowledge Service referenced in DODI 8500.01. For devices accommodating banners of 1300 characters, the banner text is: You are accessing a U.S. Government (USG) Information System (IS) that is provided for USG-authorized use only. By using this IS (which includes any device attached to this IS), you consent to the following conditions: -The USG routinely intercepts and monitors communications on this IS for purposes including, but not limited to, penetration testing, COMSEC monitoring, network operations and defense, personnel misconduct (PM), law enforcement (LE), and counterintelligence (CI) investigations. -At any time, the USG may inspect and seize data stored on this IS. -Communications using, or data stored on, this IS are not private, are subject to routine monitoring, interception, and search, and may be disclosed or used for any USG-authorized purpose. -This IS includes security measures (e.g., authentication and access controls) to protect USG interests--not for your personal benefit or privacy. -Notwithstanding the above, using this IS does not constitute consent to PM, LE or CI investigative searching or monitoring of the content of privileged communications, or work product, related to personal representation or services by attorneys, psychotherapists, or clergy, and their assistants. Such communications and work product are private and confidential. See User Agreement for details. For devices with severe character limitations, the banner text is: I've read & consent to terms in IS user agreem't. The administrator must configure the banner text exactly as written without any changes. SFR ID: FMT_SMF.1.1 #36

V-276866CAT IIGoogle Android 16 must be configured to not allow backup of [all applications, configuration data] to remote systems.Discussion

Discussion

Backups to remote systems (including cloud backup) can leave data vulnerable to breach on the external systems, which often offer less protection than the mobile operating system. Where the remote backup involves a cloud-based solution, the backup capability is often used to synchronize data across multiple devices. In this case, DODDoW devices may synchronize DODDoW sensitive information to a user's personal device or other unauthorized computers that are vulnerable to breach. Disallowing remote backup mitigates this risk. SFR ID: FMT_SMF.1.1 #40

V-276868CAT IIGoogle Android 16 must be configured to disable exceptions to the access control policy that prevent [selection: application processes, groups of application processes] from accessing [selection: all, private] data stored by other [selection: application processes, groups of application processes].Discussion

Discussion

App data sharing gives apps the ability to access the data of other apps for enhanced user functionality. However, sharing also poses a significant risk that unauthorized users or apps will obtain access to DODDoW sensitive information. To mitigate this risk, there are data sharing restrictions, primarily from sharing data from personal (unmanaged) apps and work (managed) apps. If a user is allowed to make exceptions to the data sharing restriction policy, the user could enable unauthorized sharing of data, leaving it vulnerable to breach. Limiting the granting of exceptions to either the administrator or common application developer mitigates this risk. Copy/paste of data between applications in different application processes or groups of application processes is considered an exception to the access control policy and therefore, the administrator must be able to enable/disable the feature. Other exceptions include allowing any data or application sharing between process groups. SFR ID: FMT_SMF.1.1 #42, FDP_ACF_EXT.1.2

V-276869CAT IIGoogle Android 16 must be configured to disable multiuser modes.Discussion

Discussion

Multiuser mode allows multiple users to share a mobile device by providing a degree of separation between user data. To date, no mobile device with multiuser mode features meets DODDoW requirements for access control, data separation, and nonrepudiation for user accounts. In addition, the MDFPP does not include design requirements for multiuser account services. Disabling multiuser mode mitigates the risk of not meeting DODDoW multiuser account security policies. SFR ID: FMT_SMF.1.1 #47a

V-276871CAT IIGoogle Android 16 must be configured to disable ad hoc wireless client-to-client connection capability.Discussion

Discussion

Ad hoc wireless client-to-client connections allow mobile devices to communicate with each other directly, circumventing network security policies and making the traffic invisible. This could allow the exposure of sensitive DODDoW data and increase the risk of downloading and installing malware on the DODDoW mobile device. SFR ID: FMT_SMF_EXT.1.1/WLAN

V-276872CAT IIGoogle Android 16 users must complete required training.Fix text, Discussion

Fix text

All Google Android 16 device users must complete training on the following training topics (users must acknowledge that they have reviewed training via a signed User Agreement or similar written record): - Operational security concerns introduced by unmanaged applications/unmanaged personal space, including applications using global positioning system (GPS) tracking. - Need to ensure no DODDoW data is saved to the personal space or transmitted from a personal app (for example, from personal email). - If the Purebred key management app is used, users are responsible for maintaining positive control of their credentialed device at all times. The DODDoW PKI certificate policy requires subscribers to maintain positive control of the devices that contain private keys and report any loss of control so the credentials can be revoked. Upon device retirement, turn-in, or reassignment, ensure that a factory data reset is performed prior to device handoff. Follow mobility service provider decommissioning procedures as applicable. - How to configure the following UBE controls (users must configure the control) on the Google device: **Secure use of Calendar Alarm. **Local screen mirroring and mirroring procedures (authorized/not authorized for use). **Do not upload DODDoW contacts via smart call and caller ID services. **Do not configure a DODDoW network (work) VPN profile on any third-party VPN client installed in the personal space. **If Bluetooth connections are approved for mobile device, types of allowed connections (for example, car hands-free but not Bluetooth wireless keyboard). **How to perform a full device wipe. **Use default Wi-Fi hotspot password: 15-character complex Wi-Fi hotspot preshared password enabled ("WPA2/WPA3-personal") - AO guidance on acceptable use and restrictions, if any, on downloading and installing personal apps and data (music, photos, etc.) in the Google device personal space.

Discussion

The security posture of Google devices requires the device user to configure several required policy rules on their device. User-Based Enforcement (UBE) is required for these controls. In addition, if the authorizing official (AO) has approved the use of an unmanaged personal space, the user must receive training on risks. If a user is not aware of their responsibilities and does not comply with UBE requirements, the security posture of the Google mobile device may become compromised, and DODDoW sensitive data may become compromised.

By default, when Wi-Fi Hotspot is enabled, a 15-character complex password is automatically configured for the hotspot. Configuration API: DISALLOW_CONFIG_TETHERING

Discussion

Wi-Fi and Bluetooth hotspot use may increase the risk for exposing sensitive DODDoW data for some use cases; therefore, it should be disabled unless approved by the AO. When a DODDoW mobile phone is used as a Wi-Fi or Bluetooth hotspot, a hotspot password must be enabled; otherwise, unauthorized devices could connect to the DODDoW hotspot, which may increase the risk of exposure of sensitive DODDoW data and/or a performance degradation of the DODDoW mobile phone.

How these changes are found

Checks are matched across the two releases by V-number. A check counts as updated when DISA gave it a new rule revision (the r number in its SV-…_rule id) and its title, severity, check text, fix text, discussion, CCIs or other fields changed — the same comparison STIG Compare makes. Added checks are new V-numbers; removed checks are V-numbers V1R4 no longer has.
