WAF Request Processing Demo

What is a WAF?
A Web Application Firewall (WAF) protects web applications by filtering and monitoring HTTP traffic between a web application and the Internet. It typically follows a set of rules that help prevent vulnerabilities in web applications and combat various attack vectors.

How Does a WAF Work?
A WAF operates through a set of rules often called policies. These policies aim to protect against vulnerabilities in the application by filtering out malicious traffic. The filtering can be done through:

• Blacklisting: Blocking specific requests that match known attack patterns
• Whitelisting: Allowing only requests that match pre-defined patterns
• Hybrid: Combining both approaches

Common Threats WAF Protects Against:

• SQL Injection (SQLi)
• Cross-Site Scripting (XSS)
• Cross-Site Request Forgery (CSRF)
• File Inclusion
• Security Misconfigurations
• Malicious Bots
