Fix Recommendation

Install a configuration profile to force encrypted backups to iTunes.

Check Contents

Review configuration settings to confirm "Force encrypted backups" is enabled in iTunes (Windows) or Finder (Mac).

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 "Encrypt local backup" is checked.

Alternatively, verify the text "<key>forceEncryptedBackup</key><true/>" 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 Apple iOS/iPadOS management tool containing the restrictions policy.
5. Tap "Restrictions".
6. Verify "Encrypt local backup" is listed.

If "Encrypt local backup" is unchecked in the Apple iOS/iPadOS management tool, or "<key>forceEncryptedBackup</key><false/>" appears in the configuration profile, or the restrictions policy on the iPhone and iPad does not list "Encrypt local backup", this is a finding.
