Impact of Denial of Service Attack on the Virtualization in Cloud Computing

Abstract

Cloud computing is the fastest growing technology in the IT world. The technology offers reduced IT costs and provides on the demand services to the individual users as well as organizations over the Internet. Cloud computing offers infrastructure as a service (IaaS). IaaS provides infrastructure including software, hardware, storage space, network bandwidth to the users on demand over the internet. Cloud computing makes use of virtualization to provide infrastructure as a service. Virtualization is based on the concept that multiple tenants can use the same physical machine with multiple operating systems. Virtualization comprises the vulnerability of Denial of Service (DOS) attack that can affect the performance of cloud computing. A malicious VM attacker can compromise the other guest VM or the host OS. The paper explores the TCP SYN flood attack over the other guest VM by a malicious VM attacker coexisting in the virtualized cloud infrastructure. Different Parameters are analyzed over the victim VM to detect the TCP SYN flood attack
