Title

The Google Android Pie must be configured to enforce an application installation policy by specifying an application whitelist that restricts applications by the following characteristics: [selection: list of digital signatures, cryptographic hash values, names, application version]. (Cat II impact)

Discussion

The application whitelist, 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 pre-installed applications. Core application: Any application integrated into the OS by the OS or MD vendors. Pre-installed application: Additional non-core applications included in the OS build by the OS vendor, MD vendor, or wireless carrier. Requiring all authorized applications to be in an application whitelist prevents the execution of any applications (e.g., unauthorized, malicious) that are not part of the whitelist. Failure to configure an application whitelist properly could allow unauthorized and malicious applications to be downloaded, installed, and executed on the mobile device, causing a compromise of DoD data accessible by these applications. The application whitelist, 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 pre-installed 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 pre-installed applications.

Check Content

Review Google Android device configuration settings to determine if the mobile device has an application whitelist configured. Verify all applications listed on the whitelist have been approved by the Approving Official (AO). This validation procedure is performed only on the MDM Administration Console. On the MDM console, do the following: 1. Go to the Android app catalog for managed Google Play. 2. Verify all selected apps are AO approved. NOTE: Managed Google Play is always a Whitelisted App Store. If on the MDM console the list of selected Managed Google Play apps included non-approved apps, this is a finding. (Note: The application whitelist will include approved core applications (included in the OS by the OS vendor) and pre-installed 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 pre-installed applications.) For Google Android, there are no pre-installed applications.

Fix Text

Configure the Google Android device to use an application whitelist. On the MDM Console: 1. Go to the Android app catalog for managed Google Play. 2. Select apps to be available (only approved apps). 3. Push updated policy to the device. NOTE: Managed Google Play is always a Whitelisted App Store.
