Able to copy between Base machine and xrdp sessions

I would like to block all Non-Sudo user to copy from xrdp sessions to base-machine. Currently both way copy is possible.

Is there any way I can block copying from xrdp session to base-machines, else both ways.

You can turn off device redirection by setting 'rdpdr=false' in xrdp.ini, or even recompile xrdp without FUSE support, but it would achieve little.
If the user has a session, there are alternative ways of extracting information (e.g. email attachment, ftp or copy/paste of displayed information).
