I think I've got my internet connection security coming together, but
I'm worried about a potential back door. I have one worker who absolutely
has to have a modem to contact the legacy system our billing service
uses. What bothers me is that someone might get clever and use a war
dialer to find this number and try and hack their way around my secure
gateway. I'd like to make this more difficult or at least have some way
to contain the damage. Does anyone have any ideas? I thought of possibly
putting a linux box configured as a firewall between her and the rest of
the network, but I'd have to have alot of ports open to allow all the
services she'll need so I don't know if that would even help much.
