At present, what methods do we take to solve the attack? The first method shortens the waiting time and deletes the illegal request data packets waiting in the waiting queue as soon as possible. The second method is that the first handshake message is not put into the waiting queue. We return a 32-bit unsigned integer to the client as the Seq of the second handshake. The integer is obtained by adding a serial number of the server to the parameters requested by the user (including the requested address, port, etc.). If it is a normal user, it adds 1 as ACK after receiving this integer and returns it to the server. After receiving the data, the server subtracts 1 from this ACK and then performs inverse operation to obtain various parameters. Finally, the data sent out are compared. If they are completely consistent, it means that it is an effective response and stored in the corresponding data structure, otherwise it is not. Through this method, illegal requests cannot occupy system resources.

Responsibility chain mode:
If the message has been matched by the previous rule, iptables performs the corresponding action on the message, Even the latter rules match the current message, It is very likely that there will be no chance to perform corresponding actions on the message again. Take the above figure as an example, the message is first matched by the first rule, so the current message is "released", because the message has already been released, so even if the second rule in the above figure can match the message just "released", there is no chance to discard the message just now. This is how iptables works.
