Many mobile devices now permit a user to unlock the user's device by presenting a fingerprint to an embedded fingerprint reader. Other biometrics and token-based systems are feasible as well. None of these alternatives are currently evaluated in a Common Criteria evaluation of a mobile device against the Security Target based on the Mobile Device Fundamentals Protection Profile. Many have known vulnerabilities. Until there are DoD-approved assurance activities to evaluate the efficacy of these alternatives, they are significant potential vulnerabilities to DoD information and information systems. Disabling them mitigates the risk of their use. Touch ID is a fingerprint reader that has been installed on some models of Apple iOS devices.
If the Authorizing Official (AO) has approved the use of Touch ID, this requirement is not applicable.
Review configuration settings to confirm "Allow Touch ID to unlock device" is disabled.
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 iOS management tool, verify "Allow Touch ID to unlock device" is unchecked.
Alternatively, verify the text "
Install a configuration profile to disable Touch ID for device unlock.
