Anti-DDoS
The Anti-DDoS service protects EIPs against layer-4 to layer-7 distributed denial of service (DDoS) attacks and sends alarms immediately when detecting an attack. In addition, Anti-DDoS improves the bandwidth utilization and ensures the stable running of user services.

Understand
Anti-DDoS monitors the service traffic from the Internet to EIPs to detect attack traffic in real time. It then scrubs attack traffic based on user-configured defense policies without interrupting service running.
