I know of hosting providers that filter ports properly, will not allow in port scans, block pings, etc -- they block that at the border through their security architecture. So that would keep some attackers from knowing that certain ports are actually open. But of course the ports are truly open, how else would one run a web server that you want the public to hit without port 80 open?
You can't. Your ISP can't block only attempts to do something nasty and not things that are benign. If port 80 is blocked to portscans, it'll be blocked to web page requests too. -- Steven DeFord Security.Willworker () gmail com (925) 596-0426 --------------------------------------------------------------------------- Earn your MS in Information Security ONLINE Organizations worldwide are in need of highly qualified information security professionals.
