Virtualisation offers many benefits, but companies deploying it could be exposing themselves to new threats. 

According to Gartner, virtual systems will soon be the target of new security threats.
Virtualisation gives users the ability to run multiple operating systems on a single machine – but is opens up a new layer that could be the target of security attacks.
Neil MacDonald, a vice-president at Gartner, warns that users can't secure vitualised systems in the same way they would regular operating systems.
To compound the problem, tools for securing these systems are either immature or non-existent.
As a result of these factors, over the next three years, as many as 60% of virtual machines will be less secure.
