Abstract

As an important part of the power system, the power Internet of Things (IoT) is an effective active defense method to prevent and control security threats and strengthen the protection capability by effectively measuring and evaluating the network security risks it faces. Based on the investigation of the current situation, this paper puts forward a security risk assessment method for the power IoT. By collecting threat information, asset information and protective measures, and combining the characteristics of the power IoT, on the basis of assessing the vulnerability, asset value and the degree of asset impact, the network security risk quantified score value under the threat perspective is obtained, so as to evaluate the security risk faced more effectively. The validity of the method is verified by comparing the risk values before and after taking security measures in the scenario of distributed photovoltaic terminal access in the power IoT.
