Abstract
Attack trees provide a model to describe the security of a system based on the possibility of various attacks. In this paper, we propose the concept of “attack graphs” as an extension of attack trees, wherein directed acyclic graphs are used to depict possible attacks on a system. By deploying this model, system managers can discern all possible threats to the system and thus are more likely to design efficient countermeasures to thwart those attacks. Within this model, we also propose the concept of the most dangerous path in the attack graph, and finally propose an algorithm to expose it.
