Abstract: Intrusion tolerance is the rising third generation technology of network security.For the shortcomings of existing models of intrusion tolerant systems,a model of distributed intrusion tolerant systems is proposed through the tool of Petri net.The concrete interpretation of the model is given,and the performances of the model are analyzed in detail on the basis of examples.The results of analysis show that this model extends the description range of the existing intrusion tolerant system and can describe many of the properties of intrusion tolerant systems more particularly.
