Security control of unstructured data in the power IoT for isolation network between internal and external

Abstract

As a key national infrastructure, the safety of the power grid is an overall and strategic issue that affects the development of the national economy and society. With the popularization and development of the Internet of Things in the power industry, power Internet of Things terminal equipment has become a key target of network attacks. Using network attacks to damage power Internet of Things equipment has a strong detrimental power. As the main data storage method of the power Internet of Things, the security management and control of unstructured data has become the focus of the power Internet of Things security. This paper proposes a reformulation of access control policies based on the different attribute states and trust levels of power Internet of Things terminal equipment to reduce its access control authority, and on this basis, proposes a dynamic access control based on the isolation of internal and external networks. The detailed function design of each core security protection component is given, and the component module is explained.
