This article summaries the challenges in today's IT environments - one-third believe virtualization and cloud computing make security "harder," while one-third said it was "more or less the same," and the remainder said it was "easier."
This kind of spread between answers clearly underlines the maturity of virtualization & cloud security market - which is - very very nascent. In mature markets, terminologies or concepts, we get one answer or an answer close to the correct one. But, here, there is wide spread interpretation of terminology, concepts and solutions too. For the common IT person, my suggestion would be to go slow and understand fundamentals. Ignoring is not an option as catching up will be almost impossible.
