Check Contents

Review configuration settings to confirm "Show Notification Center in Lock screen" is disabled.

This check procedure is performed on both the Apple iOS management tool and the Apple iOS device.

Note: If an organization has multiple configuration profiles, the check procedure must be performed on the relevant configuration profiles applicable to the scope of the review.

In the Apple iOS management tool, verify "Show Notification Center in Lock screen" is unchecked.

Alternatively, verify the text "<key>allowLockScreenNotificationsView</key> <false/>" appears in the configuration profile (.mobileconfig file).

On the Apple iOS device:
1. Open the Settings app.
2. Tap "General".
3. Tap "Profiles & Device Management".
4. Tap the Configuration Profile from the iOS management tool containing the management policy.
5. Tap "Restrictions".
6. Verify "Notifications view on lock screen not allowed" is present.

If "Show Notification Center in Lock screen" is checked in the Apple iOS management tool, "<key>allowLockScreenNotificationsView</key> <true/>" appears in the configuration profile, or the restrictions policy on the Apple iOS device from the Apple iOS management tool does not list "Notifications View on lock screen not allowed", this is a finding.
