Title

Apple iOS must not allow use of iCloud Photo Sharing (also known as Shared Photo Streams). (Cat II impact)

Discussion

When iCloud Photo Sharing is enabled, sensitive photos will be automatically uploaded to Apple-specified servers and available on the IOS devices of other users who have accepted invitations to participate in iCloud Photo Sharing. This potentially places sensitive photos on a server outside of DoD's control and potentially makes them available to non-DoD users and devices. Disabling iCloud Photo Sharing mitigates this risk.

Check Content

Review configuration settings to confirm “iCloud photo sharing” 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 photo sharing" is unchecked. Alternatively, verify the text "<key>allowSharedStream</key><false/>" appears in the configuration profile (.mobileconfig file). On the iOS device: 1. Open the Settings app. 2. Tap "General". 3. Tap "Profiles" or "Profiles & Device Management" or "Device Management". 4. Tap the Configuration Profile from the iOS management tool containing the restrictions policy. 5. Tap "Restrictions". 6. Verify "Shared streams not allowed" is listed. If "Allow iCloud photo sharing" is checked in the iOS management tool, "<key>allowSharedStream</key><true/>" appears in the configuration profile, or the restrictions policy on the iOS device from the iOS management tool does not list "Shared streams not allowed", this is a finding.

Fix Text

Install a Configuration Profile to disable iCloud photo sharing.
