Immune network risk evaluation model based on the spreading of infectious diseases

Abstract

From the mechanism of infectious epidemic spreading, the theory of network epidemic spreading was studied in this paper. The process of the developments and changes of the network intrusion behaviors were analyzed, and an improved network situation awareness model on the basis of the immunity was created, which is based on the SIR model. The concepts and formal definitions of immune cells are given, and dynamically evaluative equations for self, immune tolerance and immune memory are presented, distributed management framework of the proposed model are built. An improved epidemic spreading model was proposed to study the mechanisms of aggressive behaviors spreading, to predict the future course of an outbreak and to evaluate strategies to control a network epidemic. Experimental results show that the proposed model has the features of real-time processing for network situation awareness and can improves the ability of intrusion detection. © 2013 Springer-Verlag Berlin Heidelberg.
