Abstract
An attack graph processing device includes a node extraction unit which extracts a node relating to a rule classified into a predetermined group from an attack graph that is configured from one or more nodes indicating the state of a system to be diagnosed, or the state of the primary agent of an attack on the system to be diagnosed, and one or more edges indicating the relationship among a plurality of nodes, the attack graph being generated using rules indicating a condition in which the attack can be executed, and a graph configuration unit which simplifies the attack graph on the basis of the extracted node.
