Title

Disable Hot Corners

Control

/usr/bin/profiles -P -o stdout | /usr/bin/grep -Ec '"wvous-bl-corner" = 0|"wvous-br-corner" = 0|"wvous-tl-corner" = 0|"wvous-tr-corner" = 0'

Discussion

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.
