With all the talk about cloud computing, a number of questions have arisen about how secure the cloud really is. Personally, I'm not that concerned. If implemented properly, cloud security may actually be better for cybersecurity if but for one reason: we've been down this road before.
While some may argue with the specifics, cloud computing is a modern version of the mainframe services that businesses flocked away from a decade or two ago. Now, in a reversal, many are moving to the "cloud," i.e. moving control of their computing efforts from an internal local function to a centralized computing location.
So as companies and the government ponder security in the cloud, it would be worthwhile to look back before recreating a new security regime. Mainframes, in many ways, were inherently secure. There was centralized control and the main challenges were managing user accounts and access control. These are easy challenges, especially in an distributed network environment when a mainframe has to assess whether users are who they say they are -- identification and authentication tools are critical.
