From the perspective of service, DDoS protection is essentially a war in which users are the main body and rely on anti-D protection systems to compete with hackers. In the whole process of data confrontation, service providers often have absolute initiative. Users can base on specific rules of anti-D system, such as traffic type, request frequency, packet characteristics, delay interval between normal services, etc. Based on these rules, users can better resist DDoS of the seven-layer class and reduce the resource overhead of the server on the premise of satisfying the normal service itself. The detailed schematic diagram is as follows:

When the client SYN packet arrives at the filter gateway, the SYN agent does not forward the SYN packet, but actively replies the SYN/ACK packet to the client in the name of the server. If the client's ACK packet is received, it indicates that this is normal access. At this time, the firewall sends the ACK packet to the server and completes three handshakes. The SYN agent actually replaces the server to deal with SYN attacks. At this time, the filter gateway itself is required to have strong ability to prevent SYN attacks.
