Abdulrahman Almutairi, Muhammad Sarfraz, Saleh M. Basalamah, Walid G. Aref, Arif Ghafoor · IEEE Software · 2011
The large-scale, dynamic, and heterogeneous nature of cloud computing poses numerous security challenges. But the cloud's main challenge is to provide a robust authorization mechanism that incorporates multitenancy and virtualization aspects of resources. The authors present a distributed architecture that incorporates principles from security management and software engineering and propose key requirements and a design model for the architecture.
