Discussion

A screen saver must be enabled and set to require a password to unlock. An excessive grace period impacts the ability for a session to be truly locked, requiring authentication to unlock.

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 askForPasswordDelay

If there is no result, or if "askForPasswordDelay" is not set to "5" or less, this is a finding.

Fix Text

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