Modeling and analyzing of autonomic intrusion tolerant based on PEPA

Technology of autonomic intrusion tolerant is a new hot research content. In most cases, this technology is closely related to platform and application environment. It also lacks the theoretical basis of ubiquity. This paper presents a model of intrusion tolerance based on autonomic computing. The model is designed to "evaluation layer-trap layer-executives layer" three layers. It uses PEPA to describe the process of autonomic intrusion tolerant abstractly and analyze the key factors of the process of autonomic intrusion tolerant. The results of experiment verify the rationality and robustness of the model.
