A game theoretical approach to defend against co-resident attacks in cloud computing: Preventing co-residence using semi-supervised learning

Abstract

While cloud computing has facilitated easy and affordable access to IT resources, it has also introduced a wide range of security risks from almost every layer and component of cloud systems. In this paper, we focus on one risk at the virtual machine level and the co-resident attack, where by constructing various types of side channels, malicious users can obtain sensitive information from other virtual machines that co-locate on the same physical server. Most previous work has focused on the elimination of side channels, or more generally speaking, the possible countermeasures after attackers co-locate with their targets. In contrast, we provide a different perspective, and propose a defenc..
