I was on the ubuntu forums, and a user had posted this:Always have both a hardware AND software firewall.Don't trust other computers on the same LAN implicitly. One of them may have been hacked and is being used to attack all other systemsI had some clarification questions on these:
1. I am running iptables on my server. Is this not enough? Is a hardware device recommended as well?
2. How is this acted upon? How do I protect myself internally, from these types of attacks?
