摘　　要：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。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.
