Hierarchical Network Security Situation Prediction Based on Belief Rule Base

Abstract

Aiming at the problem that the existing network security situation prediction (NSSP) can only provide the network situation predicted values but not the specific information such as threat sources, this paper proposes a hierarchical NSSP method and uses the Belief Rule Base (BRB). The hierarchical NSSP method first predicts the development trend of the state of network security elements, and then evaluates the predicted network security elements to obtain the situation predicted value. Through experimental analysis, the hierarchical NSSP method can accurately predict the network security situation and provide more reference information for network security management.
