Modeling and Analysis of SYN Flooding Attack in Power SCADA System Based on Queuing Theory

SYN flooding is one of the common ways of DoS attack in SCADA system of electric power, which poses a great threat to the security of electric power information network and attracts the attention of researchers. In this paper, the queuing theory model is used to model the SNY Flooding attack process, and the normal request queue and the attack request queue are regarded as two independent birth and death processes, and a simple solution method is proposed. The simulation results show that the formula for calculating the connection loss rate is simple and the time complexity is lower, which provides a new idea and method for analyzing DoS attacks.
