Classification: CPC G | IPC G

Claim 1:
2. The attack tree generation device according to claim 1,
wherein the system configuration data indicates a plurality of devices that perform communication and one communication path or more that connect the plurality of devices, as a configuration of the target system, and
wherein the processing circuitry generates a system configuration graph expressing the target system to include a plurality of nodes and one edge or more, based on the system configuration data, the plurality of nodes expressing the plurality of devices, the one edge or more expressing the one communication path or more, assesses centrality discussed in a graph theory, about each node in the system configuration graph, determines one node or more to serve as a dividing point of the target system based on an assessment result, and with making each of the determined one node or more a dividing point, divides the target system expressed by the system configuration graph into the plurality of sub-systems.
