Zero-trust-based power Internet of Things security protection method

Abstract

The invention discloses a zero-trust-based power Internet of Things security protection method. The method comprises the steps that an access subject performs identity registration on an identity authentication platform; wherein the access main bodies are incredible main bodies and need to be authenticated through the identity authentication platform every time an access request is initiated; an identity is given to the access subject after passing the identity authentication, wherein each identity corresponds to a corresponding access authority; an access object level is judged, and if the access object level is an important level, ACL permission verification is carried out; in the access process, safety continuous evaluation is carried out in combination with multiple factors such as anaccess subject environment, an operation risk, an external threat and an access context; and the identity of the access subject is dynamically adjusted and the access permission is dynamically adjusted according to the safety continuous evaluation result. According to the invention, the problems of gradual failure of traditional boundary security protection and immature zero-trust security protection are solved.

Description

technical field [0001] The invention relates to the field of electronic information technology, in particular to a zero-trust-based power Internet of Things security protection method. Background technique [0002] With the rapid development of the Internet technology of "big cloud, thing, smart chain and edge", it focuses on connecting power users and their equipment, power grid enterprises and their equipment, power generation enterprises and their equipment, suppliers and their equipment, and people and things. Generate shared data, and provide users, power grids, power generation, suppliers, and government social services. The construction of the Internet of Things has opened up a new path for safe operation of the power grid, lean management, precise investment, and high-quality services. In this process, all aspects of the Internet are interconnected. , The types and quantity of devices connected to the network have increased significantly, and the requirements for rea...
