A Novel Data Security Model for Cloud Computing
Since the mid 1990s, the computational systems have changed from centralized to distributed model. Emergence of virtualization changes the system architecture to virtual centralization. On the other hand, in centralized computing, there is full control on data and processes where in virtual centralization the clients dont know where the data is stored and where the processes are running. In this architecture, security is a major concern especially in network, host, application, and data levels. For specific application for instance in cloud computing that is the major focus in this paper, data security is the main concern. Because of diversity in service models which are provided in cloud computing, achieving acceptable level of security is very important. These service models are Software as a Service, Platform as a Service and Infrastructure as a Service. We have proposed a novel data security model for cloud computing based on separation of security in different category layers. The proposed model certifies that our method can improve security levels in service oriented systems, especially in cloud computing applications.
