Virtual Security: Pros Worried, but Not Doing Much About It
Eight key findings from a recent survey by Prism Microsystems.
Full virtualization, where multiple operating systems and applications are run on top of virtual hardware, allows businesses to make gains in operational efficiency by increasing the workload on existing computers. A server using full virtualization uses more of the computer's memory and processing power than several servers running a single OS and set of services. Desktop PCs using full virtualization technology can run more than one OS while supporting applications that only run on a particular operating system.
Full virtualization has drawbacks when it comes to security. The technology creates additional complexity when it comes to security management and, due to consolidation of operating systems and applications on a single system, the impact of a security compromise is greater.
The National Institute of Standards and Technology uploaded a document to the Knowledge Network that addresses security concerns. The Guide to Security for Full Virtualization Technologies provides recommendations for improving security for virtual servers and desktops.
