How Do Virtual Servers Impact Data Center Security?

Research firm Gartner argues in a new report that servers that are virtualized end up being less secure than before when it comes to network security. eSecurity Planet reports.

The rush to virtualization has yielded a major vulnerability. According to a study just released by Gartner, the majority of servers being virtualized are less secure than they were when they were separate, physical servers.

Virtualization has been used as part of a consolidation strategy to put a multitude of underutilized servers on one physical hardware unit. One modern server with lots of memory can house dozens or hundreds of virtual servers, thus saving floor space and electricity for power and cooling.

But as companies make the move, issues often crop up that weren't anticipated. In its new report, Gartner found 60 percent of virtualized servers deployed between now and 2012 will be less secure than the physical ones they've replaced, thanks to bad practices by IT departments or a lack of proper tools to do the job.

"Most virtualized workloads are being deployed insecurely. The latter is a result of the immaturity of tools and processes and the limited training of staff, resellers and consultants," said Neil MacDonald, vice president and Gartner fellow, in a statement.
