Defending against Cache-based Side-Channel Attack using Virtual Machine Migration in Cloud

The Cloud services are gaining importance in today’s world. Many recent researchers have discovered unique vulnerabilities in securing privacy and integrity of the cloud-based systems. While cloud-computing is offering many advantages over the on-premises computing conditions in multiple aspects, like accessibility, availability, cost-efficiency, and scalability, it also introduces a wide range of new difficulties related to security. Previous research have shown that there are security threats in almost every component of cloud computing architecture such as infrastructure, storage, and application. The attacker has a clear set of targets that are interrelated to the Virtual Machines. He extracts confidential information from the user by implementing their own attack procedures of Virtual Machine on the physical servers. The Cloud platform provides underlaying infrastructure to the middle layer of the software system to the application that are developed on the top of the systems. This paper majorly concentrates on a specific task that is related to cache-based side channel attacks which targets the virtualization level, from the bottom of the software stack to the top. Experimental analysis along with graphical and mathematical analysis have been performed. The existing methodologies along with designed methodology are studied, and the comparative analysis is made.
