Title

Apple iOS must not allow use of iCloud backup. (Cat II impact)

Discussion

A cloud backup feature may gather a user's information, such as PII, or sensitive documents. With this feature enabled, sensitive information will be backed up to the manufacturer's servers and database. This data is stored at a location that has unauthorized employees accessing this data. This data is stored on a server that has a location unknown to the DoD. Disabling this feature mitigates the risk of a backup feature that stores sensitive data on a server that has the ability to be located in a country other than the United States.

Check Content

Review configuration settings to confirm iCloud Backup 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 iCloud backup" is unchecked. Alternatively, verify the text "<key>allowCloudBackup</key> <false/>" appears in the configuration profile (.mobileconfig file). On the iOS device: 1. Open the Settings app. 2. Tap "iCloud". 3. Tap "Backup". 4. Verify "iCloud Backup" is off. If "Allow iCloud backup" is checked in the iOS management tool, "<key>allowCloudBackup</key><true/>" appears in the configuration profile, or iCloud Backup is toggled to the right and appears green on the iOS device, this is a finding.

Fix Text

Install a Configuration Profile to disable iCloud Backup.
