Abstract: The biological Immune System(IS) is highly complicated and aimed at detecting and removing the viruses. There’re many similarities between the computer security system and living organism’s IS. So the researches on the similarities could provide important clues about how to construct robust computer security system. Based on the theory of lymphocyte activation, a behavioral characteristic detecting model based on the self-replicating behavior of the viruses is brought forward. A validity analysis and experiment was made. The results of the experiment show that this model could become a new try to detect the viruses according to the replication behavior of the viruses. And at the same time it effectively reduces the problem of false negative and false positive in the process of distinguish between self and non-self.
