A Study on the Resource Management against Availability Attacks in Cloud Computing

摘要

In cloud computing, the computing resources in a different physical location are integrated into various services by a virtualization technology. Cloud computing has currently received significant attention due to its many advantages. However, it has security threats of the traditional IT and also has new security threats caused by the structural features of virtualized environments. In particular, availability attacks are very threatening to cloud computing due to the feature of resource sharing. In this paper, we present the scheme to analyze the workloads by allocation of new virtual machines against availability attacks on system resources. We discuss the additional role of a resource broker to threat detection and apply proper an allocation method. Also, we define some factors and analyze several equations to get a quantitative standard against attacks on system availability. System threats and workloads can be analyzed based on these factors. If some availability attacks are detected, then we can apply a proper allocation method against these attacks by using a proposed scheme.
