The attacker first completes the three-way handshake to establish the connection, but in the last ACK reply of the three-way handshake, the TCP window size is set to 0, and then a data request is made. When the attack target sends the request result to the attacker, it stops the data transmission when it finds that the TCP window size is 0, and sends out a TCP window detection packet to ask the attacker if the TCP window has been updated. Since the attacker will not update the window size, the attack target will always maintain the TCP connection and wait for the data to be sent, and continuously carry out TCP window size detection. When the number of controlled hosts in the botnet is large, Target's connection table will gradually be exhausted, resulting in denial of service.
Command mode belongs to the behavior mode of an object. Command mode encapsulates a request or operation into an object, and separates the responsibility of issuing the command from the responsibility of executing the command through abstraction of the command. The implementation of command mode can provide the functions of revocation and recovery of commands. The specific structure diagram is shown below.

Reset authentication takes advantage of the reliability of TCP protocol, and DDOS protection system responds to syn first. When the protective device receives syn, it responds to syn_ack and sets the Acknowledge number to a specific value (recorded as a cookie). When the real client receives this message and finds that the acknowledgement number is incorrect, it will send a reset message with a sequence number of cookie + 1. The source of the forgery will not have any response. In this way, we can add the real client IP to the white list. ?
