Security Service Model for Cloud Environment

Cloud computing is becoming increasingly important for provision of services and storage of data in the Internet. However there are several significant challenges in securing cloud infrastructures from different types of attacks. The focus of this paper is on the security services that a cloud provider can offer as part of its infrastructure to its customers (tenants) to counteract these attacks. We have to describes the design of the security architecture and discusses how different types of attacks are counteracted by the proposed architecture.
