Now most software systems in cloud platform use multi-tenancy architecture. A single software system serves for multiple client organization. All customers' data will not be stored in only one node. So the system needs higher data security mechanism. This paper wants to build a data security monitoring model in cloud platform for large enterprises. The model can set the authentication, logging, fine-grained access control, dynamic data filtering strategy and data audit to realize the security protection for enterprises data. The model proposed by this paper uses multi-tenancy SaaS (Software-as-a-Service) application architecture, RBAC (Role-Based policies Access Control) model and operation in the context of environmental perception to realize the data access control.
