Abstract

To provide a system that supports security measures including workaround considering availability for a system under operation.SOLUTION: There is provided a security measures planning system for an information processing system including hardware and software, and the security measures planning system comprises: an input unit that receives information on a target information processing system that executes security measures; a reference DB that stores reference information such as vulnerability information; a DB searching unit that searches for the vulnerability information in the reference DB on the basis of the information on the target information processing system received by the input unit; a similarity ratio determination unit that determines a similarity ratio of the vulnerability information searched for by the DB searching unit to the target information processing system; a countermeasures analysis planning unit that selects security measures corresponding to the vulnerability information searched for by the DB searching unit, and determines reliability to which the selected similarity ratio is added; and an output unit that outputs the vulnerability information and the security measures corresponding to the vulnerability information on the basis of the reliability.SELECTED DRAWING: Figure 1
