TEST SCENARIO GENERATION DEVICE, TEST SCENARIO GENERATION METHOD AND TEST SCENARIO GENERATION PROGRAM

The test scenario generation device of this invention is a test scenario generation device which generates a test scenario related to an attack against an in-vehicle device, comprising a storage unit which stores hierarchy information including information indicating a plurality of constituent elements equipped in the in-vehicle device and, among the constituent elements, assets that may become an attack target, an element connection which indicates a connection of the constituent elements, vulnerability information which indicates a vulnerability of each of the constituent elements, and attack classification information which indicates an attack classification of each of the vulnerabilities, an assignment unit which creates attack classification information, which has identified the attack classification of each of the constituent elements, by using the hierarchy information, the vulnerability information, and the attack classification information, and a scenario creation unit which generates an entry route up to each of the constituent elements as the assets based on the element connection, and generates a plurality of test scenarios in which a combination of the constituent elements and the attack classification is arranged in an order of the entry routes by using the attack classification information.
