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:?

The content of the website is stored on the source server, and the CDN is the cache of the content. Users are only allowed to access the CDN. If the content is not on the CDN, the CDN sends a request to the source server. In this way, as long as the CDN is large enough, it can resist great attacks. However, this method has a premise that most of the content of the website must be statically cached. For websites (such as forums) with dynamic content as the main content, we must think of other ways to minimize users' requests for dynamic data.

What I encountered was a CC attack. At most, about 20 IP addresses around the world sent requests in turn, with the number of requests per address ranging from 200 to 300 times per second. When I read the log, I felt that those requests poured in like a flood. In the blink of an eye, there were a lot of requests. In a few minutes, the volume of the log file increased by 100MB. To tell the truth, this is only a small attack, but my personal website has no protection, and the server is still shared with others. This kind of traffic immediately goes offline.
