Attack scenario generating apparatus, attack scenario generating method, and computer readable recording medium

Abstract

An attack scenario generating apparatus including: first attack step detection unit executes an attack simulation on a first virtual model obtained from a storage device in which a plurality of virtual models used to represent a target system are stored, and detects a first attack step that satisfies a damage condition with which damage occurs in the first virtual model; an input/output condition extraction unit extracts an input condition or an output condition of the first virtual model from the detected first attack step, or both the input condition and the output condition; a second attack step detection unit executes an attack simulation on a second virtual model obtained from the storage device, and detects a second attack step in which output of the second virtual model satisfies the input condition; and a combination unit combines the first attack step and the second attack step to generate an attack scenario.
