Title

The system must be configured to require case insensitivity for non-Windows subsystems. (Cat II impact)

Discussion

This setting controls the behavior of non-Windows subsystems when dealing with the case of arguments or commands. Case sensitivity could lead to the access of files or commands that must be restricted. To prevent this from happening, case insensitivity restrictions must be required.
