Embodiment 1
[0016] Low-rate denial-of-service attacks against applications with fixed communication cycles;
[0017] (1) Monitor the communication rules of the target application program on the network, and record the fixed communication cycle of the target application program;
[0018] (2) When it is necessary to carry out a low-rate denial-of-service attack against the application, first establish a synchronization relationship with a communication data packet of the application;
[0019] (3) The denial-of-service attack program periodically sends out denial-of-service attack data in accordance with the synchronized time node and the previously recorded time period;
[0020] (4) The denial-of-service attack process is completely aimed at the application program with a fixed communication cycle.
Embodiment 2
[0022] An example of an application denial of service attack targeting irregular communication cycles.
[0023] (1) Analyze the communication rules of the target application program, and determine that the application program is an application program with an irregular communication cycle;
[0024] (2) When it is necessary to carry out a denial of service attack against the application, first monitor the characteristics of the application, IP address, port number or some identifying fields in the data packet on the network;
[0025] (3) When the special identifier of the target application program appears on the network, an instant low-rate denial of service attack data is launched on the network;
[0026] (4) After the denial-of-service attack program sends data, continue to monitor the communication data flow on the network, and continue to initiate low-rate denial-of-service attack data until a new special identifier of the application is found.
