If an attacker sends SYN packets quickly with their own undisguised IP address, this is a so-called direct attack. This attack is very easy to implement because it does not involve spoofing or modifying packets below the user layer of the attacker's operating system. For example, he can simply send many TCP connection requests to implement this attack. However, for this attack to work, the attacker must also prevent his system from responding to SYN-ACK packets because of any ACK, RST, or ICMP (Internet? Control? Message? Protocol) will cause the server to skip the SYN-RECEIVED state (go to the next state) and remove the TCB (because the connection has been successfully established or recycled). Attackers can do this by setting firewall rules, causing the firewall to block all packets (except SYN) to reach the server, or causing the firewall to block all incoming packets so that SYN-ACK packets are discarded before reaching the local TCP handler.

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.
