Check Contents

Review configuration settings to confirm "Allow backup of enterprise books" 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 "Allow backup of enterprise books" is unchecked.

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

On the iPhone and iPad:
1. Open the Settings app.
2. Tap "General".
3. Tap "VPN & Device Management".
4. Tap the Configuration Profile from the Apple iOS/iPadOS management tool containing the restrictions policy.
5. Tap "Restrictions".
6. Verify "Backing up enterprise books not allowed" is listed.

If "Allow backup of enterprise books" is checked in the Apple iOS/iPadOS management tool, "<key>allowEnterpriseBookBackup</key> <true/>" appears in the configuration profile, or the restrictions policy on the iPhone and iPad does not list "Backing up enterprise books not allowed", this is a finding.
