Title

Apple iOS must not allow diagnostic data to be sent to an organization other than DoD. (Cat III impact)

Discussion

The sending of diagnostic data back to the manufacturer is prohibited in the DoD. Sending this data to an organization other than DoD is termed a “phone-home” vulnerability. This setting may enable the device manufacturer to gather sensitive location data or other information about the user’s practices. This data will be sent to the manufacturer's servers and database. This data is stored at a location which has unauthorized employees accessing this data. By disabling this feature the phone home risk will be mitigated.

Check Content

This check procedure is performed on the iOS Over-the-Air 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 Over-the-Air management tool, verify "Allow sending diagnostic and usage data to Apple" is unchecked. For example, in Mobile Iron Admin Portal: 1. Ask the MDM administrator to display the "POLICIES & CONFIGS". 2. Click or tap on the word "Configurations". 3. Click or tap the configuration name. 4. Expand "Details" under "App Setting Details". 5. Verify "Allow diagnostic data to be sent to Apple" is set to "false". Alternatively, verify the text "<key>allowDiagnosticSubmission</key><false/>" appears in the configuration profile (.mobileconfig file). On the iOS device: 1. Open the Settings application. 2. Tap "General". 3. Tap "About". 4. Tap "Diagnostics & Usage". 5. Verify that "Don't Send" is checked. If "Allow sending diagnostic and usage data to Apple" is checked in the iOS Over-the-Air management tool, "<key>allowDiagnosticSubmission</key><true/>" appears in the configuration profile, or if "Automatically Send" is checked on the iOS device, this is a finding.

Fix Text

Configure Apple iOS not to send diagnostic data to an organization other than DoD. In the iOS Over-the-Air management tool, uncheck "Allow sending diagnostic and usage data to Apple". For example, in Mobile Iron Admin Portal, edit the configuration and deselect "Allow diagnostic data to be sent to Apple".
