Infrastructure-as-a-Service (IaaS) is an important service type provided by cloud computing. Infrastructure resources are encapsulated into services and they are provided to users over the Internet in the form of virtual machines. A malicious user can upload malicious software into the virtual machine allocated by a cloud computing service provider and launch the side channel attacks to other virtual machines located in the same physical node by operating their own virtual machine. In order to address the above problem, this paper proposes an efficient anomaly detection framework for cloud computing environment to detect the virtual machines that present abnormal behaviors.
