high-profile, good reputation products. And then, if there is a special relationship or agreement with the network provider, it is better, when a large number of attacks occur, it is very effective to ask them to make a traffic limit at the network point to fight against certain kinds of DDoS attacks.2, try to avoid the use of NATWhether it is a router or a hardware protection wall device to avoid the use of Network address translation NAT, because t

After hackers have invaded a large number of hosts beforehand, to install DDoS attack on the victim host to

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
