With the construction of power information network, the power grid has built a security protection system based on boundary protection. However, with the continuous advancement of the construction of the power Internet of Things, a large number of power Internet of Things terminals need to connect to the power information network through the public network, which have an impact on the existing security protection system of the power grid. This article analyzes the characteristics of the border protection model commonly used in network security protection. Aiming at the lack of security protection capabilities of this model, a zero-trust security architecture-based power Internet of Things network security protection model is proposed. Finally, this article analyzes and studies the application of zero trust in the power Internet of Things.

The construction of the power Internet of Things has led various terminals to access the corporate network on a large scale. The internal and external business interaction and data exchange are more extensive. The current security protection system is based on border isolation protection. This is difficult to meet the needs of the power Internet of Things connection and open shared services. This paper studies the application scheme of the ``zero trust'' typical business scenario of the power Internet of Things with ``Continuous Identity Authentication and Dynamic Access Control'' as the core, and designs the power internet security protection architecture based on zero trust.

Under the background of increasingly severe security situation, the new working mode of power mobile internet business anytime and anywhere has greatly increased the complexity of network interaction. At the same time, various means of breaking through the boundary protection and moving laterally are emerging in an endless stream. The existing boundary-based mobility The security protection architecture is difficult to effectively respond to the current complex and diverse network attacks and threats, and faces actual combat challenges. This article first analyzes the security risks faced by the existing power mobile Internet services, and conducts a collaborative analysis of the key points of zero-trust based security protection from multiple perspectives such as users, terminals, and applications; on this basis, from identity security authentication, continuous trust evaluation, and fine-grained access The dimension of control, fine-grained access control based on identity trust, and the design of a zero-trust-based power mobile interconnection business security protection framework to provide theoretical guidance for power mobile business security protection.

With the rise of the cloud computing and services, the network environments tend to be more complex and enormous. Security control becomes more and more hard due to the frequent and various access and requests. There are a few techniques to solve the problem which developed separately in the recent years. Network Micro-Segmentation provides the system the ability to keep different parts separated. Zero Trust Model ensures the network is access to trusted users and business by applying the policy that verify and authenticate everything. With the combination of Segmentation and Zero Trust Model, a system will obtain the ability to control the access to organizations' or industrial valuable assets. To implement the cooperation, the paper designs a strategy named light verification to help the process to be painless for the cost of inspection. The strategy was found to be effective from the perspective of the technical management, security and usability.
