1. What is the difference and connection between denial of service attack and distributed denial of service attack?
The sockstreet attack first completes the tcp three-way handshake the tcp connection is established, but in the last ack reply of the three-way handshake, the attacker sets its tcp window to 0 and then makes a data request. When the target discovers that the TCP window size at the receiving end is 0 when transmitting data, it will stop transmitting data and issue a TCP window probe packet to ask the attacker if its TCP window has been updated. Since the attacker does not change the size of the tcp window, the target will always maintain the tcp connection waiting for data to be sent and continuously carry out window update detection. If the attacker uses a large number of controlled hosts to carry out sockstreet attacks, the target will always maintain a large number of tcp connections and carry out a large number of window update detection, and its tcp connection table will gradually run out.

In the termination phase of tcp connection, the connection between the client and the server is usually cut off through four interactions of messages with fin flags. However, when one of the clients or servers has abnormal conditions and cannot normally complete four tcp waves to terminate the connection, RST messages will be used to forcibly interrupt the connection.

In this architecture, data packets are first collected by splitting or mirroring for attack detection. Then the attack detection module uses the detection algorithm to detect the attack. Although there are many attack detection methods such as Depth Package Analysis (DPI) and Depth/Dynamic Flow Detection (DFI) based on machine learning principles in academia, from the perspective of engineering efficiency, building traffic models and setting security thresholds or security baselines should be the most efficient methods. Although there are many types of DDOS attacks, their purpose is unique-to consume resources. Therefore, in the attack detection phase, the type of DDOS attack is not important, what matters is whether DDOS attack has occurred. At present. Even if the attack detection method of setting traffic threshold is adopted, it still faces the problem of how to set reasonable traffic threshold in many services.
