Abstract: a hierarchical risk assessment model is designed to provide evidence for the auto plan generating process of collaborate defense. The model organizes vulnerability by using attribute based attack graph, finding out all possible attack paths and calculating possibility of each single attack path. Analytic hierarchy process is used to calculate the hierarchical risk of the network. The model provides reliable evidence for the collaborate defense to solve two important problems, that is when to response and what measures to take in the response.

Key words: risk assessment, attack graph, analytic hierarchy process
