Title

The macOS system must retain the session lock until the user reestablishes access using established identification and authentication procedures. (Cat II impact)

Discussion

Users must be prompted to enter their passwords when unlocking the screen saver. The screen saver acts as a session lock and prevents unauthorized users from accessing the current user's account.

Check Content

To check if the system will prompt users to enter their passwords to unlock the screen saver, run the following command: /usr/sbin/system_profiler SPConfigurationProfileDataType | /usr/bin/grep askForPassword If there is no result, or if "askForPassword" is not set to "1", this is a finding.

Fix Text

This setting is enforced using the "Login Window Policy" configuration profile.
