Research on the Evaluation and Prediction Model of Network Security Situation Based on Multi Sensor Data Fusion

Abstract

Along with the unceasing expansion of computer network scale, sharp growth of network user quantity, and various kinds of network security incidents also emerged in an endless stream, so computer networking faces severe challenges. At present, the research on network security is mainly concentrated on the research on intrusion detection method, but with the network's complexity and uncertainty increases, the research on network security situation is bound to become a trend. Research on network security situation warrants that the security state should be integrated into various safety factors for the whole dynamic response of the whole network, and to make timely and accurate prediction of the state of safety. This paper establishes the evaluation and prediction model of computer network security situation. After analyzing and summarizing the existing methods of some network security situation evaluation and prediction algorithm, this paper proposes a model for network security situation assessment and prediction of the trend of multi sensor data fusion.
