Research on computer immune system based on intrusion tolerance

摘要

When the body is intruded, there is a congenital immune process to find and reduce the damage as quickly as possible. This is an important recovery character for the biology immune system. A model that simulates the biology's congenital immunity is introduced in the computer immune system. It has two basal agents, Damage Detector Agent and Congenital Response Agent. Damage Detector Agent finds intrusion and releases dangerous signal to excited Congenital Response Agent. And it uses a Dynamic Semi-Active Replication technology to ensure the system can work. All this work can improve the system's robustness that it can supply the basic services when it's intruded.
