Advice needed on setting up security on Fedora installation
So now that the internet is working from home (cable connection) I now want to make sure I dont get hacked, sniffed, scanned or spoofed or whatever other evils can befall you on the net.
I read a lot about the vulnerabilities of being connected all-the-time (particularly from customers of my ISP).
I understand Fedora (my distro) comes with a default firewall (iptables?) which i'll investigate, but my question concerns switching off certain ports and so prevent hackers from exploiting my system.
My question then is - which ports do you block (and still have functional access to the internet) and how?
