基于人工免疫的网络安全态势评估模型

本文将人工免疫原理应用到网络安全态势评估的研究中。通过对入侵检测模型
中有关自体、非自体、抗原的形式化描述，建立了抗体细胞的演化机制、动态免疫记
忆、免疫监视等免疫机制。依据人体免疫系统抗体浓度的变化与病原体入侵强度的对
应关系，建立了网络安全态势实时定量计算模型。

Abstract: This paper constructs a network security situation assessment model on the basis
of biologic Immune theories. The concepts of self, nonself, antibody and antigen are defined,
and the immune mechanisms of self-tolerance、the evolution of antibody cell、dynamic
immunologic memory、immune surveillance are presented. With the relationship between
the antibody concentration and the degree of illness in the biologic immune system, a
real-time model of situation evaluation for network security based on artificial immune
system is proposed.
