Claim 6:
7. The attack tree generation device according to claim 5,
wherein the processing circuitry
when there are a plurality of intrusion courses to the root system in the target system, selects a descendent system group being one descendent system or more, in units of intrusion courses,
generates a descendent tree group being one descendent tree or more, in units of descendent system groups, and
searches a plurality of descendent tree groups corresponding to the plurality of intrusion courses, to thereby find brother trees being a plurality of child trees each having the same root node as that of a common terminal node of a common parent tree, and connects individual root nodes of the brother trees to the common terminal node via a logical disjunction gate.
