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 Zebra Android device to not send notifications to the lock screen mitigates this risk. SFR ID: FMT_SMF_EXT.1.1 #19

Check Text ( C-56315r820502_chk )
Review Zebra Android device settings to determine if the Zebra Android device displays (work container) 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 Android 11 device. On the EMM console, do the following: 1. Open "Lock screen restrictions" section. 2. Select "Work Profile". 3. Verify that "Disable Unredacted Notifications" is toggled to "On". On the Android 11 device, do the following: 1. Go to Settings >> Display >> Advanced. 2. Tap on Lock screen display. 3. Ensure "Hide sensitive work content" is listed under "When work profile is locked". If the EMM console device policy allows work notifications on the lock screen, or the Android 11 device allows work notifications on the lock screen, this is a finding.
