In his recent blog post, Securing the Cloud Stack, Geoffrey Moore posits that clouds are "as readily secured as corporate data centers, arguably more so" and that enterprise cloud security issues stem from the combination of "enterprise cloud computing with social and mobile end users." He argues that today's social/mobile apps and devices are built for employee freedom and experience, versus enterprise cloud apps, which are built to ensure security and accuracy of corporate data. This is the Systems of Record vs Systems of Engagement debate that Moore initiated, and continues to be debated. The walled garden security approaches of the past, he argues, are of no use when corporate data flows freely from cloud apps to mobile devices over the public medium that is the Internet.
Forward-looking IT executives have already begun to realize that the only way to continue to be successful is to secure corporate data (Systems of Record) AND provide the convenience that employees want (Systems of Engagement).
