A firewall could help protect against denial of service attacks by dropping
packets from attacking computers. A firewall could also block everything except
OUTBOUND traffic on port 80, in the unlikely event that the system is
compromised and it tries to send information out. For example, one time I got
cracked and the person e-mailed out some information through port 25.
