Fix Recommendation

Install a configuration profile to disable Notification Center from the device Lock screen.

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/iPadOS management tool and the iPhone and iPad.

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/iPadOS 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 iPhone and iPad:
1. Open the Settings app.
2. Tap "General".
3. Tap "Profiles & Device Management" or "Profiles".
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/iPadOS management tool, "<key>allowLockScreenNotificationsView</key> <true/>" appears in the configuration profile, or the restrictions policy on the iPhone and iPad does not list "Notifications View on lock screen not allowed", this is a finding.
