Since yesterday my RH 5.2 machine has a connection to the internet via a
cablemodem. All works fine. But, since I know that the internet isn't
safe these days I want to place some security on my computer before I
let it run 24 hours a day. So, I have installed a simple firewall to
ensure that nobody can get to my netwerk and so. But, I also know that
RH has some security holes on its own. What should I do the make my
machine run more securerely?
