What is the role of FortiWeb in defending against application layer (Layer 7) DDoS attacks?

FortiWeb, as a Web Application Firewall (WAF), is specifically engineered to protect web applications and APIs from Layer 7 DDoS attacks, which target application resources. It employs techniques such as Behavioral Analysis to detect unusual traffic patterns and request rates, advanced Bot Mitigation using CAPTCHA challenges and IP reputation, HTTP Protocol Validation to drop malformed requests, and granular Rate Limiting to prevent HTTP floods and slow-drip attacks like Slowloris. By focusing on application logic and user behavior, FortiWeb ensures that legitimate traffic reaches the application while malicious requests are blocked.
