Identity and access management for cloud web services

Cloud computing plays an important role in fulfilling the present day organizational requirements. The recent attraction of cloud web services due to its availability and cost effectiveness is achieved by different flexible service models like, IaaS, SaaS, PaaS and multi tenancy. The privacy and security risks associated with these service models are high. In order to minimize the risks in cloud web service, organizations require a strong, flexible, scalable and accountable Identity and Access Management (IAM) system. In this paper, we propose an integrated identity and attribute based access management system for cloud web services. The combination of authentication and attribute based access control provides improved security to the cloud web service.
