Bugtraq: Re: def-2001-10: Websweeper Infinite HTTP Request DoS

[Derek Kwan <dkwan () KWAN CA>]

Dumb question... How's a FW going to prevent people connect to the web
port and issue this kind of Infinite HTTP request?

Unless the FW also have some kind of realtime IDS build into it to block
traffic in realtime... Am I correct?
