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:

In TCP implementation, when receiving the SYN request from the client, the server needs to reply the SYN + ACK packet to the client, and the client also needs to send the confirmation packet to the server. Usually, the initial serial number of the server is calculated by the server according to certain rules or adopts random numbers. However, in SYN cookies, the initial serial number of the server is obtained by hash operation and encryption of the client IP address, client port, server IP address, server port and other security values, which is called cookie. When the server suffers from SYN attack and makes the backlog queue full, the server does not reject the new SYN request, but replies the cookie (SYN serial number of the reply packet) to the client. If it receives the ACK packet from the client, the server subtracts 1 from the ACK serial number of the client to obtain the cookie comparison value, and performs a hash operation on the above elements to see if it is equal to the cookie. If equal, complete the three-way handshake directly (Note: At this time, you don't need to check whether this connection belongs to the backlog queue).
