Big Sur - Disable Hot Corners

Information

Hot corners _MUST_ be disabled.

The information system conceals, via the session lock, information previously visible on the display with a publicly viewable image. Although hot comers can be used to initiate a session lock or to launch useful applications, they can also be configured to disable an automatic session lock from initiating. Such a configuration introduces the risk that a user might forget to manually lock the screen before stepping away from the computer.

Solution

This is implemented by a Configuration Profile.
