Hi folks,
Can IIS7 automatically block IP addresses if certain queries are tried against my server? Like, is it smart enough to figure out that it's getting spammed by similar requests from the same IP under a short peroid of time?
e.g.
Here are some stats from my log files today :
#Software: Microsoft Internet Information Services 7.0
#Version: 1.0
#Date: 2009-09-12 00:28:22
#Fields: date time s-ip cs-method cs-uri-stem cs-uri-query s-port cs-username c-ip cs(User-Agent) cs(Referer) sc-status sc-substatus sc-win32-status sc-bytes cs-bytes time-taken

Nothing serious, but just a pain in the butt. Yes, they all 404'd. But now it's also possible that this spammer/bot/script kiddie knows my IP exists AND that I'm a webserver. Yes, I'm being way over-paranoid but I'm trying to play devil's advocate here.
So if we get hit by a bot/script that has some query in it, say Toata+dragostea+mea+pentru+diavola (that's the user agent in this case) or /admin/phpmyadmin/js/keyhandler.js (an actual resource), then can this be auto-blocked?
