Check

This check procedure is performed on the device management tool and iPhone.

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 iOS management tool, verify "Allow iPhone Mirroring (supervised only)" is unchecked.

On the iPhone/iPad device: 1. Open the Settings app. 2. Tap "General". 3. Tap "VPN & Device Management". 4. Tap the Configuration Profile from the iOS management tool containing the restrictions policy. 5. Tap "Restrictions". 6. Verify "iPhone Mirroring not allowed" is listed.

If "Allow iPhone Mirroring" is not disabled in the management tool or "iPhone Mirroring not allowed" is not listed on the iPhone, this is a finding.

Fix

Install a configuration profile to disable iPhone Mirroring on Mac. This is a supervised-only control.

Configuration Profile Key: allowiPhoneMirroring
