To acquire the network security situation of the future,a network security situation forecast method based on D-S evidence theory is proposed.First,a network security situation forecast model based on D-S evidence is brought forward,to fuse the impact of previous and current network security situation on the future network security situation,the uncertainty is reduced and the probability of each network security situation is gained in the next time.With this method,absolute forecast of network security situation is avoided.Then the validity and accuracy of this method is validated by experiments.Consequently,this method provides a new solution for network security situation forecast.
