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.
