Research on Information Security System of Smart City Based on Information Security Requirements

In the process of smart city construction, information security is an important factor to ensure the sustainable development of smart city. The paper focuses on information security problems in the construction of smart city, and explores the overall framework and construction contents of information security system. First of all, the paper summarizes the characteristics of smart city information system, and analyzes the requirements for information security. Then, combined with the relevant standards and norms of information security, the paper puts forward construction ideas of information security system. On this basis, the overall framework of information security system is constructed with a global perspective, which includes three systems:management system, technology system, construction and operation system. At the same time, the construction contents and guarantee strategies of each system are put forward. The establishment of information security system helps to ensure safe management and operation of smart city. This research provides a reference for the related research of information security in smart city.
