Discussion

Users must authenticate 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

Verify the macOS system is configured to prompt users to enter a password to unlock the screen saver with the following command:

/usr/bin/osascript -l JavaScript << EOS
$.NSUserDefaults.alloc.initWithSuiteName('com.apple.screensaver')\
.objectForKey('askForPassword').js
EOS

If the result is not "true", this is a finding.

Fix Text

Configure the macOS system to prompt users to enter a password to unlock the screen saver by installing the "com.apple.screensaver" configuration profile.
