Reset authentication takes advantage of the reliability of TCP protocol, and DDOS protection system responds to syn first. When the protective device receives syn, it responds to syn_ack and sets the Acknowledge number to a specific value (recorded as a cookie). When the real client receives this message and finds that the acknowledgement number is incorrect, it will send a reset message with a sequence number of cookie + 1. The source of the forgery will not have any response. In this way, we can add the real client IP to the white list. ?

This leads to an obvious potential DoS attack. Incoming SYN packets will be allocated too many TCB and the host's kernel memory will be exhausted. In order to avoid this memory depletion, the operating system usually associates a "backlog" queue parameter with the listening interface, which maintains both the upper TCB number of connections and the SYN-RECEIVED state. Although this scheme protects the host's available memory from attack, the backlog queue itself brings a (small) source of attack. When there is no space in the backlog, it is impossible to respond to new connection requests unless the TCB can be recycled or removed from the SYN-RECIEVE state.
A brief introduction is as follows:
