Abstract

We describe our model for the behaviour of an attacker. In the model, the attacker has uncertain knowledge about a computer system. Moreover, the attacker tries different attack paths if initially selected ones cannot be completed. The model allows finer-grained analysis of the security of computer systems. The model is based on Markov Decision Processes theory for predicting possible attacker's decisions.
