How we do IT is fundamentally changing. Applications are increasingly being accessed from mobile devices while cloud computing offers a new approach to application delivery. Case in point, the iPhone adoption rate is 8 times faster then AOL was! As a result corporate application portfolios are shifting in their mix of total to partial to no IT manager control. IT leaders are finding that the largest application growth in their corporation is coming from outside of their traditional perimeter/firewall with no control knobs. In essence applications and networks are becoming borderless and as a result a new flexible security model is needed to reestablish boundaries. To address this industry concern, I talk with Fred Kost Director Security Solutions for Cisco Systems about a new approach to securing networks without borders.
