Hi list members
The current topic "My Windows Box got rooted" has prompted me to
consider the potential risks associated with a project I am currently
researching. Naturally, I call upon the collective wisdom of these
hallowed pages for advise, guidance and comment.
I have recently given my grand children who live in the Wagga area a PC
of their own. This PC is a linux only box (cos I didn't have a copy of
windows to give them and I figure exposing them to alternatives is a
healthy approach). It sits as part of a small home network sharing with
Windows XP and a Printer connected to to the Windows box. All this
works well and both file and printer sharing are working.
As I'm sure that at some point they are going to break something with
this system, I have been researching how to set this box up to allow SSH
over the internet through which I plan to tunnel VNC (I hope) in the
hope that I may be able to fix up damage if it occurs without driving to
My research has revealed that for all this to happen, Port 22 needs Port
Forwarding enabled. Fine...I now know how to set this up within their
router but the process is not a simple one and ideally should be left
open for the Wagga family's sake ( not strong on the finer points of
computing at this stage). So now I am thinking how do I make this
system as secure as possible. Will a software firewall close the gap?
What happens if they manage to break the system to the point where it
may be impossible to operate a software firewall and a host of other
points that I haven't thought through yet.
So any comments, advise, guidance would be most welcome as I am on a
fairly steep learning curve with this.
My thanks in advance for your help
Regards to all
