一种新的DDoS攻击预警方法
Novel approach of DDoS forewarning
摘要
Abstract
Research on DDoS attack is one of the hotspots in network security field.Forecasting the probability of DDoS attack is highly significative of defending and responding DDoS attack at its early stage.In this papor,a forewarning model for DDoS attack based on Probable Finite State Automation (PFSA) is proposed.Moreover,a method to calculate the probability of making attack and the degree of expectation threat is presented.Experiment indicates that the method proposed in this paper can calculate probability and expectation damage of DDoS attack effectively,which achieves the goal of early defence.关键词
