How does F5 BIG-IP's application-layer firewall (WAF) contribute to a holistic DDoS defense?

The BIG-IP WAF plays a crucial role in a holistic DDoS defense by protecting against application-layer attacks that often accompany DDoS attacks. It can filter malicious HTTP requests, block SQL injection attempts, and prevent cross-site scripting (XSS) attacks. By focusing on application vulnerabilities, the WAF helps to prevent attackers from exploiting those vulnerabilities to amplify the impact of a DDoS attack.
