2. Distributed Denial of Service is divided into attack network bandwidth resources, attack system resources and attack application resources
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.

Factory Pattern: Factory Pattern is a frequently used pattern. Classes implemented according to Factory Pattern can generate instances of one of a group of classes according to the provided data. Usually, this group of classes has a common abstract parent class and implements the same methods, but these methods perform different operations for different data. First of all, we need to define a base class. Subclasses of this class implement methods in the base class through different methods. Then you need to define a factory class that can generate different subclass instances according to conditions. After getting an instance of a subclass, developers can call methods in the base class regardless of which subclass instance is returned.
