Research On Information Security Risk Factors Identification And Management Strategy Of Smart City

The development and application of new-generation information technology has raised the mining,integration and utilization of information resources in smart cities to a new level,which is conducive to better play the value of information,promote the sustainable development of cities and improve the quality of life of residents.However,emerging information technology in the process of utilization has triggered changes in the information landscape,which may bring more serious information security problems in smart cities and even cause serious impacts on social property and personal safety.Therefore,it is important to reduce the probability of information security risks and maintain the sustainable development of smart cities by studying the connotation of information security risks in smart cities,constructing a risk element index system,so as to identify the key elements affecting the information security of smart cities and proposing corresponding management strategies in a targeted manner.This paper grasps the actual situation of information security risk management in smart cities by combing the literature related to information security in smart cities,and takes it as the basis of research,constructs an index system of information security risk elements in smart cities by using the rooting theory,and also identifies and analyzes key elements by using the fuzzy DANP method,and finally proposes management strategies to reduce information security risk and improve risk response capability according to the importance of the elements in the system.First,the literature and current situation of information security of smart cities are sorted out to understand the relevant background and policy support of the research on information security of smart cities,to clarify the purpose and significance of the research on information security of smart cities,and to discuss the relevant concepts of smart cities,information security and information security risk of smart cities and the theoretical basis of the research.Secondly,using the rooting theory,starting from the interview data obtained from semi-structured interviews,we sort out the information security impact elements of smart cities through several stages,such as open coding,spindle coding,selective coding and saturation test,and construct an index system of information security risk elements of smart cities.Again,the basic principles of constituting the fuzzy DANP method are introduced,the four quadrant diagram of causality is drawn,and the key influencing factors in the index system are identified according to the correlation between cause analysis,result analysis and weight ranking.Finally,based on the identified key risk serious and combined with the information ecology theory,the relevant countermeasures to reduce the information security risk of smart city are proposed in four aspects: ensuring the controllability of information security,strengthening the management level,enhancing the technology application and creating an orderly environment.
