Check Text ( C-54919r3_chk )
Review configuration settings to confirm “Allow managed apps to store data in iCloud” is disabled. This check procedure is performed on both the iOS management tool and the iOS device. Note: If an organization has multiple configuration profiles, then the check procedure must be performed on the relevant configuration profiles applicable to the scope of the review. In the iOS management tool, verify "Allow managed apps to store data in iCloud" is unchecked. Alternatively, verify the text "allowManagedAppsCloudSync " appears in the configuration profile (.mobileconfig file). On the iOS device: 1. Open the Settings app. 2. Tap "General". 3. Tap "Profiles" or "Profiles & Device Management" or "Device Management". 4. Tap the Configuration Profile from the 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 iOS management tool, "allowManagedAppsCloudSync " appears in the configuration profile, or the restrictions policy on the iOS device from the iOS management tool does not list "Managed apps cloud sync not allowed", this is a finding.
