One border that remains to be crossed is the border between consumer technology and business technology. But it's a barrier that will be crossed one way or another — sometimes against the wishes of IT policy makers.
"In the enterprise, there is growing demand for the acceptance of new computing tools — both hardware and applications — that first gain their popularity in the consumer space before being pulled into the business organization by employees," writes Tom Gillis in his book Securing the Borderless Network. "Industry analysts generally recognize this trend as the consumerization of IT."
The positive side of this trend is that it represents opportunities to enhance the user's experience and productivity while driving down IT costs for certain applications. The trouble with this trend is security. How do organizations protect their users, their networks and their data when endpoints are beyond control?
The biggest driver of consumerized IT today is the smartphone. Handheld devices are increasingly powerful and the array of applications now available on them continues to explode. Indeed, the smartphone may be the primary computing device of mobile users in the borderless enterprise in the coming years. This raises the challenge of how to secure them and other forms of consumer IT.
"Desktop virtualization is a big part of the answer," contends Gillis. "It is a powerful tool that helps business and personal computing coexist on a single device. The concept is that consumers can have any device they want... But when the time comes to access company data, they must switch to a virtual desktop."
Such moves create a virtual environment in which policies can be rigorously enforced. Every connection can be scanned, logged and analyzed to ensure these policies are followed.
While Gillis acknowledges that the virtual desktop concept will take several years to implement effectively with emerging smartphones, he sees several meaningful steps that can be taken toward this destination in the meantime. He points, for instance, to the convergence of SSL VPN technology, advanced web security, and hybrid-hosted security solutions as a key enabler of secure networks.
While acknowledging that virtualization is only one facet of the security challenge ahead, he emphasizes that there is no holding back the flood of demand that will come from users to integrate business and personal technology. Fortunately, smart enterprises will also have the tools to protect their networks.
