Emerging trends in computation such as cloud computing require that computation be carried out in remote and hostile environments, where attackers have unlimited access to the devices, the data and the programs. Recent exploration into the unique security challenges of cloud computing have shown that when virtual machines belonging to different customers share the same physical machine, new forms of side channel communication appears. The flexibility of virtual machines running on a cloud service, presents a variety of security concerns. However, by only allowing service-provider VMs and enforcing rigorous management of VM images, many of these challenges can be overcome. However, the handling of security incidents in the cloud seems much more challenging as desires of the customers investigating a security breach run contrary to the privacy interests of the cloud service provider. In this paper, we explore cache base side channel attacks on cloud along with few security challenges.
