ENSREdm: E-government Network Security Risk Evaluation Method Based on Danger Model

In this study, we propose a danger model based security risk evaluation method to ensure the security of E-government networks. With the concepts and formal definitions of antigen, antibody, danger signal and detection lymphocyte presented, the architecture is given. Following that, the method of E-government network intrusion detection is described. And then, the security risk evaluation method is discussed. Theoretical analysis and experimental results show that the proposed method is valid. Thus, it provides a novel security guarantee solution to E-government networks.
