Erm... I had a typo on that last file. Here is the fixed version.

Cheers

Hello nmap-dev,

Here is my NSE script to determine if a http web server is protected by a Web Application Firewall (WAF), Intrusion Detection System (IDS) or Intrusion Prevention System (IPS). I'd be great if I can get some feedback from users with access to other untested WAF/IDS/IPS products.

This script tries to determine if an IDS/IPS/WAF is protecting a http server. To do this the script will send a "good" request and record the response, afterwards it will match this response against new requests containing malicious payloads. In theory, web applications shouldn't react to malicious requests because we are storing the payloads in a variable that is not used by the script/file and only WAF/IDS/IPS should react to it. If aggro mode is not on, the script will only do the minimum number of requests (Most known/noisy vectors)

This script has been tested against:
 * Apache ModSecurity
 * Barracuda Web Application Firewall
 * PHPIDS

Since the majority of IDS/IPS/WAF's protect web applications in the same way, it is likely that this script detects a lot more of these IDS/IPS/WAFs solutions.
