As mentioned above, SYN attacks can be prevented by increasing the backlog queue. In addition, reducing timeout time also enables the system to process more SYN requests. We know that the timeout timeout, that is, the half-connection lifetime, is the sum of the timeout times that the system waits for all retransmissions. The larger this value, the longer the half-connection takes up the backlog queue and the fewer SYN requests the system can handle. In order to shorten the timeout time, it can be realized by shortening the retransmission timeout time (usually the first retransmission timeout time) and reducing the number of retransmissions.CDN refers to the static content of a website distributed to multiple servers so that users can access it nearby to improve the speed. Therefore, CDN is also a method of bandwidth expansion, which can be used to defend against DDOS attacks.Ding Rui was bold and was the first to lie down.
