Fix Recommendation

Install a configuration profile to disable Siri while the device is locked.

Check Contents

Review configuration settings to confirm that Siri is disabled on the Lock screen.

This check procedure is performed on both the Apple iOS management tool and the Apple iOS device.

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 Apple iOS management tool, verify "Allow Siri while device is locked" is unchecked.

Alternatively, verify the text "<key>allowAssistantWhileLocked</key><false/>" appears in the configuration profile (.mobileconfig file).

On the Apple iOS device:
1. Open the Settings app.
2. Tap "General".
3. Tap "Profiles & Device Management".
4. Tap the Configuration Profile from the Apple iOS management tool containing the restrictions policy.
5. Tap "Restrictions".
6. Verify "Siri while locked not allowed" is listed.

If "Allow Siri while device is locked" is checked in the Apple iOS management tool, "<key>allowAssistantWhileLocked</key><true/>" appears in the configuration profile, or the restrictions policy on the Apple iOS device from the Apple iOS management tool does not list "Siri while locked not allowed", this is a finding.
