Assessment Title
Rule Text
The macOS system must disable login to other users' active and locked sessions.
Description
Discussion Text
The ability to log in to another user's active or locked session must be disabled.
WARNING: This rule may cause issues when platformSSO is configured.
macOS has a privilege that can be granted to any user that will allow that user to unlock active users' sessions. Disabling the administrator's and/or user's ability to log in to another user's active and locked session prevents unauthorized people from viewing potentially sensitive and/or personal information.
Note: Configuring this setting will change the user experience and disable TouchID from unlocking the screen saver. To restore the user experience and allow TouchID to unlock the screen saver, run "/usr/bin/sudo /usr/bin/defaults write /Library/Preferences/com.apple.loginwindow screenUnlockMode -int 1". This setting can also be deployed with a configuration profile.
Satisfies: SRG-OS-000104-GPOS-00051, SRG-OS-000109-GPOS-00056
