The Design And Implementation Of Multi-layer Cloud Platform Security Protection

Along with the advance of information technology and the improvement of computing and information storage requirements,the personal computer of computing and storage capacity is limited,so the cloud computing platform is produced.Cloud computing platform can significantly reduce the cost of computing and storage,but people are very concerned about the security of cloud computing platform.In an open cloud computing platforms,because of the traditional network security plan is not used to,and cloud computing platform architecture and technology is very complex,so the safety of the cloud computing platform has been without a mature plan.On the basis of the traditional network security protection technology,the article analyzes the cloud computing platform network security protection scheme,puts forward a multi-level cloud security protection mechanism,expect to improve the capability of cloud platform safe protection.This paper firstly combed the cloud platform and the research status of safety protection,summarize main security issues of cloud computing platform and source of threat.Then the article summarizes and analyzes the Cloud platform security protection technology,mainly including Amazon Web services,Microsoft Azure,and Google Cloud,on the basis of theoretical research,this article has carried on the system requirements analysis,overall architecture and the system design and detailed design,including image encryption system design,application isolation sandbox design based on AOP and distributed log collection system design.Article separates the encryption operation with cloud services platform,to ensure that in the case of a virtual machine possible loopholes,cloud platform user data is still not harmed.Dynamic aspect injection technology can monitor the Java API,to ensure the control ability of the user code.Finally,the article implements and tests the system.After the test,this paper implemented multi-level cloud platform security protection system can meet the design requirements,can be used in the real environment.
