Energy analysis of security for cloud application

Cloud brings in a set of unparalleled benefits as well as a host of security threats. Strong security is the key to reap the benefits of cloud computing. While it is a known fact that cloud adoption saves energy consumption as it leverages technologies like virtualization, there are times when cloud also increases instances of energy consumption due to extra security controls required. This paper highlights some of the key security challenges and controls in cloud and compares energy consumption prospect of these controls with traditional data center scenarios. In this paper, we try to formulate extra energy requirements for the desired level of security controls in cloud environment. Different cloud deployment model were considered while doing this analysis. In the concluding section, we also discuss the possible recommendations that can bring down the energy consumption while maintaining the required security level for cloud data and applications.
