Detection of Intrusion and Preserving Privacy for Data in Cloud Storage System

Cloud Computing plays a vital role in IT field which develop the field of computer in fast manner. Cloud Computing is nothing but sharing of resources to their clients in efficient way. It works under the concept of virtualization and by three different types of service providers such as SaaS, IaaS and PaaS. In cloud computing we come across some problems in security and data stored in the cloud server. We assume that an attacker can be located either outside or inside of the virtual networking system. The attacker’s primary goal is to exploit vulnerable VMs and compromise them as zombies. Our protection model focuses on virtual-network-based attack detection and reconfiguration solutions to improve the resiliency to zombie explorations. Our work does not involve host-based IDS and does not address how to handle encrypted traffic for attack detections. Our proposed solution can be deployed in an Infrastructure-as-a-Service (IaaS) cloud networking system, and we assume that the Cloud Service Provider (CSP) is benign. We also assume that cloud service users are free to install whatever operating systems or applications they want, even if such action may introduce vulnerabilities to their controlled VMs. Physical security of cloud server is out of scope of this paper. We assume that the hypervisor is secure and free of any vulnerability.
