Securing a web application using WAF

Introduction:

This humor work was my final project to get my Bachalor's in Computer Science after three years of studying at Univercity of Algers.
WAF in short of Web Application Firewall, this technologie allow you to protect a web application from many layer 7 attacks (application layer of OSI model) such as: SQL Injection, DoS, DDoS, XSS, ...etc.
WAF act like a bariare between the web application and the user, filtering HTTP/HTTPS and block mulousuce request follow a list of predefined rules called policies.
The most powerful point of WAF is that you are able to deal with a large number of web application at the same time, as we know it is quit impossible to make a perfect application with zero vulnerabilities, because as much you need to secure your application and block attacks, you have to allow legistimate users access it.
