"To say this is simple is an understatement. Mason's going to do the dirty work for you. While you're making all kinds of tcp/ip connections, Mason will create firewall rules that match those kinds of traffic. When we've finished learning, we'll tell the system to block everything that Mason didn't already learn. This creates a very strict firewall that exactly matches what this machine will need to do in the future...."
"Let's look at the setup. You'll need a Linux computer. It needs bash and a bunch of standard system tools (cat, grep, ifconfig, awk, etc) - ones that would be included in a distribution. If you have RedHat, Suse, Caldera, Mandrake, or Debian, the tools were included on your CD. In fact, if any are missing, Mason will warn you before it starts so you can install them...."
"A traditional firewall is usually constructed on a machine that's already a router, but Mason is equally usable on a router or just a normal workstation or server. You might want to try Mason out on your own workstation first to get a feel for it."
