Description
Many mobile devices display notifications on the lock screen so that users can obtain relevant information in a timely manner without having to frequently unlock the phone to determine if there are new notifications. However, in many cases, these notifications can contain sensitive information. When they are available on the lock screen, an adversary can see them merely by being in close physical proximity to the device. Configuring the mobile operating system (MOS) to not send notifications to the lock screen mitigates this risk. SFR ID: FMT_SMF_EXT.1.1 #18

Review managed Google Android 13 device settings to determine if the Google Android 13 device displays (work profile) notifications on the lock screen. Notifications of incoming phone calls are acceptable even when the device is locked. This validation procedure is performed on both the EMM Administration Console and the managed Google Android 13 device. On the EMM console: COBO: 1. Open "Lock screen" settings. 2. Open "Lock screen restrictions". 3. Verify that "Disable unredacted notifications" is toggled to "ON". COPE: 1. Open "Lock screen" settings. 2. Open "Lock screen restrictions". 3. Select "Work Profile". 4. Verify that "Disable unredacted notifications" is toggled to "ON". ___________________________ On the managed Google Android 13 device: COBO: 1.
