Claim 8:
9. The risk evaluation and countermeasure planning method according claim 8, wherein
on a basis of a plurality of components of the system, a connection relation between the plurality of components, and the vulnerability information which relates to the components, an attack route connected to the components from a starting point for the attack is generated, and
on a basis of an order of attack methods present for the attack route, the vulnerability which relates to the attack methods, and the security test, an asset value and an occurrence probability of a threat event occurring are generated, the asset value and occurrence probability being held by each of the components, and
an additional countermeasure for reducing the occurrence probability to be an occurrence probability that is less than or equal to a requirement with respect to the asset value is planned.
