Check Contents

Review configuration settings to confirm backup in management apps is disabled and iTunes Backup is encrypted.

Note: iTunes Backup is implemented by the configuration policy rule "Force encrypted backups", which is included in AIOS-12-010800, and therefore, not included in the procedure below.

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 backing up app data is disabled.

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 "Apps".
6. Tap a managed app.
7. Verify "App data will not be backed up" is listed.
Note: Steps 6 and 7 must be performed for each managed app.

If backing up app data is not disabled in the Apple iOS management tool or "app data will not be backed up" is not listed for each managed app on the Apple iOS device, this is a finding.
