Configuring an application installation policy on Samsung Knox for Android by specifying an application repository involves two steps: (1) Disabling Google Play, (2) Disabling unknown application sources. This validation procedure covers the first of these steps. It is performed on both the MDM Administration Console and the Samsung Knox for Android device. On the MDM Administration Console: 1. Ask the MDM administrator to display the "Enable Google Play" setting in the "Android Restrictions" rule. 2. Verify it is disabled. On the Samsung Knox for Android device: 1. Attempt to locate the "Google Play" application. 2. Verify it is not present on the device. If the "Enable Google Play" is not disabled, or if a user can successfully launch Google Play on the device, this is a finding.
