The principle is that syn messages are first responded to syn_ack by DDOS protection system. With a specific sequence number (recorded as a cookie). The real client returns an ack and the Acknowledge number is cookie+1. The fake client will not respond. In this way, we can know that the clients corresponding to those IP are real and add the real client IP to the white list. The next access passes directly, while other forged syn messages are intercepted. The following is a schematic diagram of protection:?

Reflective attacks typically use protocols that do not require authentication or handshake, The reflection attack needs to forge the source ip address of the requested data into the ip address of the target. If the protocol used requires authentication or handshake, the authentication or handshake process cannot be completed and the next attack cannot be carried out. Therefore, most reflection attacks are carried out by network services based on udp protocol.
