The present invention is provided with a threat analysis processing unit that, on the basis of an analysis result from the vulnerability analysis unit, analyzes a threat to the system and outputs a threat analysis result; a countermeasure planning unit that, on the basis of the threat analysis result and vulnerability information, plans the countermeasure plan which reduces the impact of the vulnerability; a security test planning unit that plans the security test on the basis of the countermeasure plan; an evaluation calculation unit that performs an evaluation on the basis of the security test, and outputs an evaluation result; and a result processing unit that processes the evaluation result and generates a security countermeasure.

Risk evaluation and countermeasure planning system, and risk evaluation and countermeasure planning method

A security design planning support device which supports planning of a security design of an in-vehicle network, includes: a strategy policy creation unit which creates first strategy policy information representing a plurality of control strategies corresponding respectively to threats against the in-vehicle network; a merge processing unit which merges control strategies of a same type among the plurality of control strategies represented by the first strategy policy information created by the strategy policy creation unit and groups the plurality of control strategies; and a communication unit which externally outputs second strategy policy information representing a relationship of the threats and the plurality of control strategies grouped by the merge processing unit.
