Understanding Virtualization Security: Strategies for Hypervisors and Hosts

Virtualization platforms are software. All software has flaws. Therefore, virtualization platforms have flaws. Simple logic,right? The major virtualization platform vendors, VMware, Xen (now Citrix), and Microsoft, have all had several vulnerabilities over the last few years. However, the major components of a virtualization infrastructure and the IT strategy related to deployment and maintenance of virtualization technologies can be planned and secured fairly well. The following sections will explore the major areas of concern for security professionals.. I. Hypervisor security The hypervisor is a piece of software, in many cases, unless integrated directly with the host platform (see the next section). The major virtualization vendors release patches for their products like any other software providers, and the key to mitigating the risk of hypervisor vulnerabilities is a sound patch management process. Examples of sound patch management practices include maintaining the latest service packs for both guests and hosts, alleviating any unnecessary applications that have a history of vulnerabilities, and applying the latest security rollup patches if and when they are supplied by the virtual software vendor. II. Host/Platform Security The host platform, which connects the VMM and virtual guests to the physical network, can vary widely in the type of configuration options available. This is largely dependent on system architecture; for example, VMware's ESX Server platform has a number of similarities to Red Hat Linux. Given that many of these systems are able to be hardened considerably, a number of The link for this article located at DataCenter Journal is no longer available. . Virtualization security ensures the integrity and availability of virtual environments, focusing on hypervisor protection, host safeguards, network security, compliance, and recovery.
