Summary:To provide a cyber attack countermeasure support system, method and program for designing an appropriate countermeasure against a cyber attack.SOLUTION: A cyber attack countermeasure support system 1000 designs countermeasures against a cyber attack on a predetermined target system. The cyber attack countermeasure support system comprises: a storage unit 120 that stores one or more attacker profiles 122 including an attack purpose and attack technique of an attacker performing the cyber attack, and one or more defender profiles 123 including a defense purpose and defense technique of a defender performing defense against the cyber attack; and a countermeasure design unit 111 that uses a system model 121 for reproducing a state of the target system and outputting index values of one or more indices indicating a performance of the target system corresponding to the state of the target system to design a countermeasure for each of combinations of the attacker profiles 122 and the defender profiles 123.SELECTED DRAWING: Figure 1 【課題】サイバー攻撃に対する適切な対処を設計するサイバー攻撃対処支援システム、方法及びプログラムを提供する。【解決手段】所定の対象システムへのサイバー攻撃に対する対処策を設計するサイバー攻撃対処支援システム1000において、サイバー攻撃を行う攻撃者の攻撃目的と攻撃手法とを含む1以上の攻撃者プロファイル122サイバー攻撃に対する防御を行う防御者の防御目的と防御手法と、を含む1以上の防御者プロファイル123とを記憶する記憶部120及び対象システムの状態を再現し、対象システムの状態に対応する対象システムの性能を示す1以上の指標の指標値を出力するシステムモデル121を用いて、攻撃者プロファイル122と防御者プロファイル123との組み合わせ毎に対処策を設計する対処策設計部111を備える。【選択図】図1
