Adaptive Intrusion Tolerance Strategy of the System Based on Artificial Immune

A new idea for studying the ability for computer to bear and process viruses after suffering from the intrusion of the viruses was discussed in this paper. This ability was named intrusion tolerance. Starting from the intrusions, capturing the behavioral characteristics and dynamically adopting different strategies enable the system to continue to provide security services. In the mean time, applying artificial intelligence to intrusion tolerant system can adaptively adjust and learn according to the extent of damage caused by attack. Establishing behavioral database was proposed for the first time. This method can avoid updating a large number of virus database frequently, realize the coordinative detection and early warning among the different servers and further improves the ability for computer to prevent and process the viruses.
