Research on the Methodology of Verification of Vital Digital Assets

摘要

In order to investigate the methodology of VDA verification, we reviewed the overview of simulators which are representative facilities of verification environments for cyber security, and the current status of simulator operations inside and outside of the R.O.K. And we examined verifition methodology that can be applied in this study. In addition, we have found that targets, initiating events, codes, and scenarios are required for this verification environments and applied these requirements into example of accidents. In this study, we used the methodology of VDA identification that was studied previously. It will be possible to identify targets and events through the derived result, and the scenario based on this will be applied to the verification environments to be developed in the future. Then we can reach a goal of this study to describe each of these scenarios in the verification environments and to describe the impact of the target sets when they are attacked and when the protection sets have succeeded in protecting them. Through this, it will be possible to verify the effects of cyber attacks on VDA, and it will be possible to develop ways to more effectively regulate cyber security at nuclear power plants.
