大数据环境下智慧城市信息安全保障体系构建研究

Purpose/significance] The information security problems faced by smart cities underthe big data environment are becoming more and more prominent. Based on this, building an informationsecurity assurance system of smart cities with comprehensive perception, system operation and collaborativeintegration under the big data environment, optimizing information security management of smart citiesunder the big data environment and perfecting the current information security construction of smartcities have certain theoretical significance and practical value. [Method/process] Applying total qualitymanagement theory to the research of smart city information security assurance system, based on the fourbasic connotations of information security, this paper built the basic structure of smart city informationsecurity assurance system under the big data environment with the help of the four phases of the PDCAcycle. [Result/conclusion] This research solves the problem of smart city information security through thePDCA cycle, which is in line with the characteristics of continuous dynamic adjustments in the process ofurban construction and development, and provides references for the entire process of ensuring smart cityinformation security under the big data environment. It mainly includes: in the planning stage, directions+ goals, norms + constraints, plans + indicators; in the implementation phase, the organizational structure,infrastructure and technical system; in the control phase, situational awareness, emergency response and riskmanagement; and in the improvement phase , the multi-agent coordination of the government, operators andthe public.
