Pounding out the UNIX System entry in the Office window will not help keep
people out of UNIX.  It is possible from any window to type "!sh<cr>" and
get into UNIX, expert user or not.  The only way to create real security
in the system is to LOCK EVERYTHING!  Put passwords on all logins (including
tutor and install and root), Set the main directories at 775 or 755 at the 
very least (by main I mean /, /etc, /bin, /usr, etc.) and set the ownership
and groups very carefully.  I checked to see what the protections are on one
of our public UNIX systems here at Holmdel and used them as a starting point.
And remember to set umask at 022 or so.
