Cloud Security Challenges and Intrusion and Detection System in Cloud Computing

Cloud computing is an upcoming technology that affects IT infrastructure, network services, and applications. Cloud security plays an important role which has attracted a lot of research and development effort in past few years. It is essentially one of the most important and on demand services technologies that IT offers today. It attempts to provide services to users on pay as use basis of the services provided in the cloud. With its various service models, It promises to reduce the operational and costs for the service providers on one hand, and for the users by providing the opportunity to access services according as per the end user needs. It is a new computing model that makes the IT world to use services that help in outsourcing data, computing and so on. However, security is an important concern. Adversaries are able to launch DDoS (Distributed Denial of Service) attacks. These attacks compromise some of the Virtual Machines and then perform DDoS activities. The compromised Virtual Machines are known as zombies. With respect to cloud computing networks detecting and countermeasure of zombies exploration attacks is difficult.
