A New Virtualization-Based Security Architecture in a Cloud Computing Environment
Cloud computing finally emerged on the stage of the information technology. Virtualization is the core of cloud computing. Virtualization minimizes capital, operational and maintenance costs. Also, it provides flexibility in the used platform. However, the expansion of cloud computing is impeded by the lack of the security issue. Physical resources are exposed to security threats and malware attacks. Therefore, the system is subject to data loss, denial of service, performance degradation, and even hardware damage. This paper proposes a new security architecture based on two frameworks described in the literature. Therefore, the paper explores both frameworks, analyzes them, criticizes them, and then highlights their advantages and disadvantages.
