In the past, many firewalls detected DDoS attacks based on a pre-set traffic threshold, exceeding a certain threshold, and generating an alarm event.The finer ones may set different alarm curves for different flow characteristics ., so that when an attack occurs suddenly, such as a SYN Flood, the SYN message in the network will exceed the threshold, indicating that a SYN flood attack has occurred.But when t
