摘要
A system dividing unit (110) divides a target system into a plurality of sub-systems. A root system selection unit (122) selects a sub-system in which a threat on security occurs, as a root system from among the plurality of sub-systems. A root tree generation unit (131) generates an attack tree of the root system, as a root tree. A descendant system selection unit (132) selects one sub-system or more located on an intrusion course to the root system, as one descendent system or more from among the plurality of sub-systems. A descendant tree generation unit (133) generates one attack tree or more corresponding to the one descendent system or more, as one descendent tree or more. A sub-attack tree integration unit (140) integrates the root tree and the one descendent tree or more, to thereby generate an attack tree of the target system.
