Automatically block banned IP addresses on IIS
Help stop automated brute force attacks and vulnerability scans
This script was written to help stop automated brute force attacks against your IIS web server. Are you tired of seeing www.yourdomain.com\\..\\..\\..cmd.exe in your log files? This script uses a custom 404 page that logs the IP address of the person making the 404 requests and after so many requests it will automatically add the blocked IP to the IIS servers deny list. There is some HOWTO information with the download...Be sure to read the README.html file!
NOTES:
1) Your server will need to have Microsoft.NET version 1.1.4322+ installed
2) Your server will need to have Active State Perl installed
