摘要
In the present invention, a system dividing unit (110) divides a subject system into a plurality of sub-systems. From the plurality of sub-systems, a root system selection unit (122) selects, as a root system, a sub-system in which a security threat occurs. A root tree generation unit (131) generates, as a root tree, an attack tree of the root system. From the plurality of sub-systems, a descendant system selection unit (132) selects, as one or more descendant systems, one or more sub-systems positioned on the intrusion route to the root system. A descendant tree generation unit (133) generates, as one or more descendant trees, one or more attack trees corresponding to the one or more descendent systems. A sub-attack tree integration unit (140) generates an attack tree of the subject system by integrating the root tree and the one or more descendant trees.
