When Desktops Go Virtual Virtualization Security. Addressing security challenges in your virtual desktop infrastructure A Trend Micro White Paper | February 2011 WHEN DESKTOPS GO VIRTUAL I. VIRTUAL DESKTOP INFRASTRUCTURE Server virtualization is well on its way to becoming mainstream. Enterprises have achieved significant savings in hardware and operating cost by optimizing resource utilization. This widespread acceptance is due in part to advanced virtualization technologies which have further increased the availability of mission-critical resources. Having experienced the cost and efficiency benefits of virtualization in the data center, many enterprises are eager to extend those same advantages into other areas of their business. This has fueled a new wave of virtualization—at the desktop. Enterprises are looking to virtualize desktops to lower costs, speed provisioning, and streamline support and management—often on a much bigger scale than at the data center. With Desktop Virtualization, often also referred to as VDI, customers can leverage a multitude of stationary and mobile devices to access their desktop, which is actually running on powerful, centralized server in the data center. VDI combines the robust virtualization technology known from server virtualization with advanced session management and innovative network protocols to provide a user experience very similar to working on a dedicated desktop PC. However, overall resource utilization is much more efficient as the server hardware is shared by tens of desktops—all while completely isolating each from the other. . One of the strengths of VDI is its ability to support a full range of desktop types and desktop use cases,
