There are powerful market forces changing IT delivery. IT application delivery is becoming increasingly centralized thanks to data center server virtualization plus mobile and cloud computing. Desktops are being virtualized, too, thanks to network speeds that deliver low latency and high bandwidth, creating a thin client user experience that is indistinguishable from a thick client but at lower desktop management cost. One serious implication of this concentration of IT in data centers is that a new IT security model is needed as mobility brings greater threat exposure while virtualization changes traffic patterns and the rules of security appliance placement. In this Lippis Report Research Note, we present a new model for IT security in the virtualized mobile and cloud-computing era.
