Ensure Screen Saver Hot Corners Are Secure For Current User
Description
Hot Corners can be configured to disable the screen saver by moving the mouse cursor to a corner of the screen. This can only be accomplished by the current user, so that is the only user that needs to be audited. Setting a hot corner to disable the screen saver poses a potential security risk since an unauthorized person could use this to bypass the login screen and gain access to the system.
