Rapid evacuation of virtual machines on a datacenter under cyber attack over optical infrastructure

Virtualization technologies are becoming increasingly common in recent years. One of the major problems in institutions and organizations using virtualization technology is cyber attack to servers. In case of an attack, not only one or a few virtual machines are under the risk, but all datacenters in the cloud face the risk of cyber attack. These attacks result in data loss is increasing dramatically. Users that take these services keep many critical and important data, programs, or systems in these cloud computing environments. In case of data loss or stolen data, corporations served experience major monetary loss and prestige loss. Besides, even though up-to-date security techniques take countermeasures against cyber attacks, damages on data and systems can still be occurred in cloud systems and many cloud computing systems may be unavailable for a long period of time In this case, service providers have to pay huge amounts to their customers due to security contracts made with their users. In this study, it's discussed that is development of a security model for cleaning virtual machines by taking them to quarantine centers in case of a cyber attack to a cloud system formed by datacenters connected over an optical network and for avoiding dissemination of attack to other datacenters on the same optical network. This model helps to minimized size of the damage due to cyber attack by rapidly migrating virtual machines under the risk of malware infection to other locations by taking the warnings provided by intrusion detection mechanisms into consideration.
