Power Internet of Things security vulnerability evaluation method integrating service security

Abstract

The invention relates to the technical field of power internet of things, and particularly relates to a power internet of things security vulnerability evaluation method integrating service security.The method comprises the steps of acquiring an attack tree model of a target power internet of things, data corresponding to each leaf node in the attack tree model and at least one evaluation index;determining the weight of at least one evaluation index based on the data of each leaf node; calculating the security vulnerability of each leaf node by using the weight of the at least one evaluationindex and the at least one evaluation index; determining the security vulnerability of each node in the attack tree model according to the security vulnerability of each leaf node and the relationship between each node in the attack tree model and the corresponding child node; and based on the security vulnerability of each node, performing security protection on the corresponding node of the power Internet of Things. After the security vulnerability of each node is calculated, security protection can be carried out on each node in a targeted manner, so that the security protection accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of electric power Internet of Things, in particular to a method for evaluating security vulnerability of electric power Internet of Things that integrates business security. Background technique [0002] The power Internet of Things is an intelligent service system for the interconnection of all things and human-computer interaction for power systems. Its business is very extensive, which can be generally divided into internal business such as customer service and power grid operation, and external business such as virtual power plant and multi-station integration. Compared with traditional power grid services, these services require more data collection and transmission, more extensive objects of information interaction, more frequent information interactions, wider scope of information sharing, and greater granularity of information mining. More in-depth, higher degree of business data, stronger business ...
