基于人工免疫的網(wǎng)絡(luò)安全態(tài)勢(shì)評(píng)估模型

本文將人工免疫原理應(yīng)用到網(wǎng)絡(luò)安全態(tài)勢(shì)評(píng)估的研究中。通過對(duì)入侵檢測(cè)模型
中有關(guān)自體、非自體、抗原的形式化描述，建立了抗體細(xì)胞的演化機(jī)制、動(dòng)態(tài)免疫記

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.
Key words: artificial immune system; network security situation assessment; network
