Check Contents

Review configuration settings to confirm "Allow managed apps to store data in iCloud" 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 "Allow managed apps to store data in iCloud" is unchecked.

Alternatively, verify the text "<key>allowManagedAppsCloudSync</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 Apple iOS management tool containing the restrictions policy.
5. Tap "Restrictions".
6. Verify "Managed apps cloud sync not allowed" is listed.

If "Allow managed apps to store data in iCloud" is checked in the Apple iOS management tool, "<key>allowManagedAppsCloudSync</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 "Managed apps cloud sync not allowed", this is a finding.
