Well, the best installation would be to have a seperate firewall box upstream from your server (cool graphics to followSmilie

(internet) =====> (firewall) -------> (webserver)

If you don't have ports open, you can't attack them. That's as simple as it is. But it may be good just to keep people from scanning and probing the box.

Also, you can set it up to help protect from becoming the man in the middle of an attack; i.e. Someone magically roots your box through an insecure CGI script, manages to open a remote shell on a high port.

Firewall Ports

Could someone please settle an inter-office argument? Will your network traffic be slower through a firewall on any other port other than port 80. In other words, is port 80 faster than any other port you open on the firewall. I say no. Thanks in advance for the help! (2 Replies)
