Body work as follows: (1) The study of cloud computing security services and technical support and cloud computing standards at home and abroad are summarized, and the key technologies of the IAAS layer are studied in detail, and the existing two open source cloud platforms are compared and analyzed to find out their advantages and disadvantages. (2) Detailed analysis of the nine threats posed by Cloud Security Alliance (Cloud), and a detailed investigation of the unique threat of the IAAS layer, and the mapping relationship based on the correlation between the two alliance,csa. Then, by investigating and analyzing the security of the data center and virtual network, this paper classifies the related technologies and protective measures for the security of the IaaS layer, and finally forms the security evaluation model of the IAAS layer. (3) Analyze and verify the validity of the model presented in this paper. Set up the index hierarchy tree based on the evaluation model, according to the expert method, the judgment matrix is established, the judgment matrix is solved by the product method, the weights of each index are obtained by the consistency verification, then the single index evaluation data of two open source platforms are obtained by the form of questionnaires, and the fuzzy evaluation method is used to evaluate the fuzzy judgment from low to high Finally, the security of the platform is judged according to the principle of maximum membership degree, and the validity of the model is validated.
