<div dir="ltr">I was on the ubuntu forums, and a user had posted this:<br><br>Always have both a hardware AND software firewall.<br>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 systems<br><div><br></div><div>I had some clarification questions on these:</div><div>
1. I am running iptables on my server. Is this not enough? Is a hardware device recommended as well? <br>
2. How is this acted upon? How do I protect myself internally, from these types of attacks?
