DDoS Attack Defense UDDoS

DDoS Attack Defense provides customers with DDoS attack protection products. Including two types of defense methods, one is through the high-defense computer room, and the other is directly resisting DDoS attacks (cleaning) on the IP bandwidth.

	Introduction	Advantages	Disadvantages
UDDoS	Provides DDoS attack protection for registered domain names or original station IPs (including elastic public IPs outside of Surfercloud). When the user’s domain name or original station IP (including the elastic public IP of non-Surfercloud) is under a large-flow DDoS attack, the original station IP can be hidden from the user through the high-defence IP proxy, and the attack traffic is diverted to the high-defence IP to ensure the stable and normal operation of the original station.	It can resist larger attacks and can support a maximum protection capacity of 1.2T. It also supports the original station IPs of Surfercloud and non-Surfercloud.	It needs to replace the new IP, the operation is more complicated, and it takes some time to switch to the high defense.
UClean	UClean is a self-developed product that provides DDoS attack protection for the elastic public IP of Surfercloud. With years of attack and defense experience accumulated, it adopts multiple defense strategies and supports defense network layer attacks, such as TCP class message attacks, SYN Flood attacks, ACK Flood attacks, etc.	There is no need to change the IP, it can be switched at the second level when attacked, and it responds with lower latency.	It cannot resist larger attacks, and currently can only support up to 10G protection. It only supports the elastic public IP of Surfercloud, not the IP outside of Surfercloud.
