Virtualisation has allowed IT managers to have a concise and constant view of their infrastructure activity.

Speaking at the RSA Europe Conference, Tom Heiser, chief operating officer at RSA, said that by integrating into a system a single view can be gained into the IT environment, but managing security within hybrid environments is a challenge.

He said: “Cloud hosting a full range of information assets and journey is a multi-step process starting with virtualisation, which dramatically improves IT efficiency and culminated in a service which we consume from cloud providers. The fact is in a virtual environment, visibility and control become even more important, virtual computing environments are fluid but boundaries transform new security challenges.

“In a recent Forbes report IT executives stated that security was the number one concern to full virtualisation adoption but these executives are moving forward in spite of concerns, in fact in 2009 reached tipping point where there were more virtual than physical machines.”

He claimed that a security executive from a pharmaceutical company told him that 65 per cent of his servers had been virtualised and this had outpaced his capabilities, while another CISO told him that security was such a concern to virtualisation that 'we are flying blind'.

“But with so many security concerns, does virtualisation create more security challenges or is it part of our solution? Virtualisation creates a secure layer to orchestrate servers, storage and desktops and is a single vantage point to enforce secure data and to provide secure vantage controls. Without this layer we must build hundreds of connectors, with virtualisation you can provide rapid information about the infrastructure,” he said.
