Research On E-commerce Security Risk Assessment Model For Cloud Computing Environment

Cloud computing has many advantages such as low cost, large scale, versatility,scalability so that it has been widely used in various fields of human social life,economic life,which is another revolution of the information society.The use and popularity of cloud computing in e-commerce make a new and powerful impetus to the rapid development of e-commerce,which promote e-commerce to a new stage-the wisdom stage.E-commerce enterprises can reduce the requirements of hardwares and softwares and infrastructure costs,accelerate the speed of information transmission and processing.The introduction of cloud computing into e-commerce implementation will greatly enhance the core competitiveness of e-commerce businesses.Cloud computing in the popularity and development of e-commerce still faces a series of problems, of which the most prominent is the security issue.Although on the cloud computing model,data can be ensured unified management and real-time monitoring,the lack of safety management controls in cloud deployments,multi-tenant and resource sharing,data confidentiality and privacy issues,the lack of trust between suppliers and merchants will bring unknown security risks.In a traditional network environment,risk assessment is an effective means to address security issues. But in a cloud environment, due to unfixed security boundaries and the unique massive information processing information security is facing new challenges.How to build an effective risk assessment system in cloud compuing environment is the primary concern of e-commerce businesses and problems to be solved.Starting with the e-commerce development model of cloud environment and related security issues,this paper analyzes the existing mainstream assessment tools,evaluation criteria,methods and processes on the basis of the research results of domestic and foreign scholars,put "risk assessment as a service" as the guiding ideology on security issues cloud environment for e-commerce,presented a security risk assessment model including assets analysis module,safety knowledge module and risk assessment calculations module.At the same time,we deploy the risk assessment process to the cloud so as to realize the dynamic ongoing monitor and management of e-commerce platform.Risk assessment process is verified by experimental data,in order to achieve intelligent and dynamic security management about e-commerce systems in the cloud environment.Meanwhile,the paper also made some useful research on pricing strategies and the migration in cloud environment of information assets.
