4: Download and install a front end for iptables
You can’t assume that just because you are using Linux, you are secure. You still need some security. And the
best security you can have with Linux is iptables. The only problem with iptables is that it can be challenging
(especially for the new user). Fortunately, there are outstanding graphical front ends for iptables. One of the
best is Firestarter. This front end makes employing iptables a simple process, so you won’t keep bypassing
security out of fear of the learning curve.
