Real Security Needed for Virtualization

This isn't the first time this newsletter has warned about the need for better virtualization security. The whole issue is that virtualization is a relatively new form of computing (and yes, I do know IBM mainframes were virtualized in 1968), and many security tools haven't kept up. Add to that the fact that a single virtualized server can act as dozens of machines. Compromise that server and you can compromise the whole shooting match.

A new survey by security vendor nCircle Inc. shows just how nervous IT is. About half of those polled don't trust security in virtual environments. Meanwhile, Shavlik surveyed VMworld attendees, and while 80 percent of these folks are very concerned about the issue, only about a third have taken concrete steps to secure virtual servers.
