Title

The Google Android Pie must be configured to enforce an application installation policy by specifying one or more authorized application repositories, including [selection: DoD-approved commercial app repository, MDM server, mobile application store]. (Cat II impact)

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 DoD data accessible by these unauthorized/malicious applications. SFR ID: FMT_SMF_EXT.1.1 #8a

Check Content

Review Google Android device configuration settings to determine if the mobile device has only approved application repositories (DoD-approved commercial app repository, MDM server, and/or mobile application store). This validation procedure is performed on both the MDM Administration Console and the Android Pie device. On the MDM console, do the following: 1. Open restrictions section. 2. Open Restrictions Section. 3. Set Allow "Google Play" (Uses only Managed Google Play). 4. Ensure that Disallow is set for "Install unknown sources". On the Google device, do the following: 1. Open Settings >> Apps and notifications >> Advanced >> 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 MDM console device policy is not set to allow connections to only approved application repositories or on the Android Pie device, the device policy is not set to allow connections to only approved application repositories, this is a finding.

Fix Text

Configure the Google Android device to disable unauthorized application repositories. On the MDM Console: 1. Open restrictions section. 2. Open Restrictions Section. 3. Set Allow "Google Play" (Uses only Managed Google Play). 4. Set Disallow "Install unknown sources".
