Collaborative Network Security for Virtual Machine in Cloud Computing for Multi-tenant Data Center

Abstract

The updated version and techniques of network computing lead to development of cloud computing. This cloud computing can offer both software and hardware resources based on the demand over the Internet services. Internet services are supported by the infrastructure of data centers. Infrastructure of the Internet services is changing rapidly in the aspect of cloud computing. In such scenario, tenants in the cloud have no network boundaries; in data sharing centers, multiple tenants save their data and applications. Tenant-specific requirements are achieved with the help of network virtualization and the underlying physical network. For addressing vast and variant network requirements of tenants, multi-tenant datacenters are enabled. In this paper, the system known as a collaborative network security prototype system used in a multi-tenant data center (vCNSMS) is implemented for the development of collaborative network security prototype system that is utilized in multi-tenant data center. Firstly, security issues involved virtual machines are analyzed, Later on, basing up on Xen platform, the security-related issues are discussed and analyzed that are present in virtual network. A centralized scheme of collaboration and packet inspection at depth with an open source of UTM system is classified in vCNSMS. Various protection policies at security level are suggested for the classification and management of security rule for vCNSMS. Overall, a novel framework for virtual network is desired for controlling the inter-communication among virtual machines is implemented for high security in physical machines.KeywordsData center networkNetwork securityMulti-tenant data centersVirtual networksIntelligent processing flowCloud computing
