Cloud security: The basics

(Mary Brandel, NetworkWorld) Cloud computing is one of the most-discussed topics among IT professionals today. And not too long into any conversation about the most highly touted cloud models - software as a service (SaaS), infrastructure as a service (IaaS) or platform as a service (PaaS) - the talk often turns to cloud security.

According to Milind Govekar, an analyst at Gartner, cloud has rocketed up the list from number 16 to number two in Gartner's annual CIO survey of key technology investments. "Like with anything new, the primary concern is security," he says. In fact, the vast majority of clients who inquire about cloud, he says, would rather create a virtualized data center on their own premises - what some call a private cloud - because they're uncomfortable with the security issues raised by cloud computing and the industry's ability to address them.

"We are in the early stages of a fascinating journey into a new computing model that, for all its purported advantages, from a security and risk point of view, is a difficult thing to deal with," agrees Jay Heiser, an analyst at Gartner.[...] For this reason securing cloud computing environments will be a major focus of vendor efforts over the next year, says Jonathan Penn, an analyst at Forrester Research. In the short term, he sees users having to do a lot of the legwork, but over time, "cloud providers themselves will see the opportunity to differentiate themselves by integrating security," he says.
