Virtual Networks are Air Gapped

The definition of traditional security technologies must evolve to meet new use cases. Networks that use virtual constructs to segregate traffic are just as air gapped as physical separation. In this episode, Tom Hollingsworth is joined by Carole Warner Reece, John Osmon, and Jason Gintert discuss why the standard for hyper secure systems has always been physical separation. They look at how the terminology is being changed to support new use cases with virtual separation and whether or not those new networks can meet the high standards of the older versions. They also discuss the need for precision in terminology and how to avoid falling back on marketing terms that can create confusion with unsuspecting consumers.
