The Building of Network Security Situation Evaluation and Prediction Model Based on Grey Theory

Abstract

Network security situation evaluation and prediction is a new technology to monitor network security, and it is one of hot research domains in information security. The research situation of network security situation evaluation and prediction all over the world is analyzed. A network security situation evaluation and prediction model based on grey theory is presented. The model is divided into two stages: current network security situation evaluation modeling and future network security situation prediction modeling. The model of current network security situation evaluation using simple additive weight method is established by the threat of various services attacked. The model of future network security situation prediction adopting grey theory is built by past and current network security situation.
