A cloud document syncing feature may gather 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.

Apple iOS 8 Interim Security Configuration Guide 2014-09-16


Check Text ( C-54885r1_chk )
Review configuration settings to confirm iCloud documents & data 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 documents & data" is unchecked.

Alternatively, verify the text "allowCloudDocumentSync " appears in the configuration profile (.mobileconfig file).

On the iOS device:
1. Open the Settings app.
2. Tap "iCloud".
3. Verify "Documents & Data" is not listed.
Note: This also verifies that iCloud Drive and iCloud Photo Library is disabled.

If "Allow iCloud documents & data" is checked in the iOS management tool, "allowCloudDocumentSync "
appears in the configuration profile, or "Documents & Data" is listed, toggled to the right, and appears green on the iOS device, this is a finding.
