Virtualisation - savings not without threats

Karl Hart doesn't need to read articles or watch the evening news to know that financially motivated hackers nowadays are finding easy pickings at colleges and universities across the country.

The 35-year-old information security officer (ISO) at the University of Cincinnati need only review some of his own college's event logs to realise that academia's liberal networking environment often acts as an open invite to the criminal element cruising the internet.

“Universities and higher-ed are the first to get hit,” Hart says. “It's almost like a playground. It's like, ‘Let's try it here first.'”

So it is no wonder that Hart is spending a lot of time these days fretting over an easy-to-deploy emerging technology called server virtualisation, in which multiple operating systems and applications run on a single machine at the same time. But Hart worries that professors and other collegiate end-users, averse to any centralised control, may overlook security in a rush to deploy this new architecture.
