Review managed Google Android 13 device configuration settings to determine if the mobile device has only approved application repositories (DOD-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 13 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 13 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 13 device, the device policy is not set to allow connections to only approved application repositories, this is a finding.
