Research On Cloud Data Risk Management Based On Public Cloud Platform

At the TwoSessions this year,the Premier of the State Council proposed in the "Government Work Report" that digitalization will be sped up to create new strengths for the digital economy.We will both develop digital industry and transform traditional industries with digital technologies.We will work faster to develop a digital society,digital government,and healthy digital ecosystem as we pursue the Digital China initiative.Obviously,the vigorous development of the digital economy has become a national strategy.Cloud computing is the key support and infrastructure for the current development of the digital economy.Cloud security will guard and ensure the high-quality development of the digital economy.The potential security threats and management risks of cloud computing such as data storage and transmission security,cross-border operation of services and sharing technologies will have more or less impact on national security,social stability,data security,and personal privacy.One of the most important tasks of cloud security protection at this stage is to attach importance to user information protection,actively carry out cloud data risk assessment,and prevent data security.In order to improve cloud service providers’ perception of cloud platform data management risk and risk prevention and control capabilities,this paper designs a set of evaluation index system for cloud platform data risk management.The specific work is as follows:Firstly,the article reviews the current researches of cloud computing-related risk management theory at home and abroad.It introduces the risk management theory and data security management specification requirements,it analyzes the current situation of cloud data risk management.Then draw out the risks and insecurity factors that exist in the cloud data operation and management of the public cloud platform;Secondly,the article determines the dimension of risk identification based on the classification of cloud data assets.It uses causality diagrams and professional interviews to identify the management risk problems of various cloud data assets,then conducts risk analysis and classification;Thirdly,the article introduces Analytic Hierarchy Process(AHP)to build a structural model of cloud data management risk assessment.The model includes 1 target layer,8 first-level indicator layers and 46 second-level indicator layers.Through experts scoring,the judgment matrix is established,calculate the value of the evaluation index of each layer,then complete the risk ranking and secondary index risk grade division;Finally,the paper proposes corresponding countermeasures and decision-making strategies for cloud data risk management.The evaluation index system can evaluate the risk of public cloud data management more truthfully,accurately and conveniently.It helps to improve the cloud data security protection operation level of cloud service providers,and help a trustworthy public cloud environment become a reality.
