Information Security Risk Assessment Based on Artificial Immune Danger Theory

This paper puts forward an information security risk assessment model, which based on danger theory, and provides a risk calculation method based on this model. It aims at the problem of the strong subjectivity and improving the accuracy and real time performance of current information security risk assessment system, by reference to dynamic response characteristic of danger theory in immunology. The model can comprehensively take various assessment factors and their correlation into consideration and conduct dynamic assessment under changing risk. Finally, the effectiveness of the model in information system security risk assessment is verified through the experiments.
