Secure cloud maintenance: Protecting workloads against insider attacks

Abstract

In recent years, Cloud Computing has gained remarkable popularity due to the economic and technical benefits provided by this new way of delivering computing resources. Businesses can offload their IT infrastructure into the cloud and benefit from rapid provisioning, scalability, and cost advantages. While cloud computing can be implemented on different abstraction levels, we focus on Infrastructure Clouds such as Amazon EC2 [1] that provide virtual machines, storage, and networks. © 2012 ACM.
