If an attacker sends a large number of SYN requests with fake source addresses, the server side will consume a lot of resources to handle this semi-connection, and saving traversal will consume a lot of CPU time and memory, not to mention retrying SYN + ACK on IP in this list. TCP is a reliable protocol, and messages will be retransmitted at this time. The default number of retries is 5. The interval time of retries is doubled from 1s to 1s + 2s + 4s + 8s + 16s = 31s respectively. After the fifth time is sent out, it will take 32s to know that the fifth time has timed out, so the total is 31 + 32=63s.

Another form of SYN flooding attack is IP address spoofing. It is a little more complicated than direct attack. Attackers must also be able to replace and regenerate the original IP message with valid IP and TCP message headers. Today, there are many code bases that can help attackers replace and regenerate original IP messages.

Among them, one of the more common attacks is CC attack. It simply and roughly sends a large number of normal requests, exceeding the maximum capacity of the server and causing downtime. 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.
