Immune mechanism based computer security design

Referring to the mechanism of biological immune system, a novel model of computer security system is proposed, which is a dynamic, multi-layered and co-operational system. Through dynamically supervising abnormal behaviors with multi agent immune systems, a two-level defense system is set up for improving the whole performance: one is based on a host and mainly used for. detecting viruses; and the other is based on a network for supervising potential attacks. On the other hand, a pseudo-random technology is adopted for designing the sub-system of data transmission, in order to increase the ability of protecting information against intended interference and monitoring. Simulations on information transmission show that this system has good robustness, error tolerance and self-adaptiveness, although more practice is needed.
