WAF Detection
Detecting any firewalls so we can find a way to bypass them.
WAF stands for Web Application Firewall.
Its goal is to protect the website behind it by filtering/monitoring the traffic.
Fingerprinting is a method used to gather information (about any WAF in this context).
Tools
Detecting WAFs with WAFW00F
Detecting WAFs with WhatWaf
Another script called http-waf-detectcan be used. It detects IDS/IPS/WAF but doesn't give information about the vendor, or version...
Other examples
A manual testing workflow could be to check the cookies and response headers.
Cookies: some WAF can be identified by the cookie's name.
Response headers: sometimes they are changed to apparently "confuse the attacker".
