Securing Cloud from DDOS Attacks Using Intrusion Detection System in Virtual Machine

Innovation is necessary to ride the inevitable tide of change. The buzzword of 2009 seems to be "cloud computing" which is a futuristic platform to provides dynamic resource pools, virtualization, and high availability and enables the sharing, selection and aggregation of geographically distributed heterogeneous resources for solving large-scale problems in science and engineering. But with this ever developing cloud concept, problems are arising from this ¿golden solution¿ in the enterprise arena. Preventing intruders from attacking the cloud infrastructure is the only realistic thing the staff, management and planners can foresee. Regardless of company size or volume and magnitude of the cloud, this paper explains how maneuver IT virtualization strategy could be used in responding to a denial of service attack. After picking up a grossly abnormal spike in inbound traffic, targeted applications could be immediately transferred to virtual machines hosted in another data center. We\´re not reinventing the wheel. We have lots of technology and standardized solutions we can already use to engineer into the stack. We are just introducing them in the way least expected.
