How can anomaly detection systems help in identifying and mitigating DDoS attacks?

Anomaly detection systems establish a baseline of normal network behavior (e.g., traffic volume, request patterns). They then monitor traffic for deviations from this baseline. Significant deviations, such as a sudden spike in traffic from a new source or an unusual request pattern, can indicate a DDoS attack. Once an anomaly is detected, the system can automatically trigger mitigation measures, such as blocking the source IP address or implementing rate limiting.
