Cloud Security: Attacks and Current Defenses
This paper presents a high-level classification of current research in cloud computing security. Unlike past work, this classification is organized around attack strategies and corresponding defenses. Specifically, the authors outline several threat models for cloud computing systems, discuss specific attack mechanisms, and classify proposed defenses by how they address these models and counter these mechanisms. This examination highlights that, while there has been considerable research to date, there are still major threats to cloud computing systems, such as potential infrastructure compromise, that need to be better addressed.
