Desktop virtualization offers many benefits, but implementing and securing the technology can be difficult. Two experts from Citrix, Peter Blum, director of product management, and Raymond Chew, senior product manager, recently spoke with ZDNet about the security challenges facing desktop virtualization. Government agencies and enterprises face certain challenges, such as access control and data isolation when utilizing desktop virtualization. Due diligence is needed to ensure commercial products address security issues, and, according to Blum and Chew, Citrix's Xen Client products can be used to combat these concerns.

"By separating the operating system from the underlying hardware, desktop images can now be created, secured, deployed and moved across any supported hardware, greatly reducing the maintenance burden on IT and simplifying disaster recovery for laptop users," they told ZDNet.

Before moving to a virtual environment, ZDNet's Daniel Kusnetzky advised, companies need to research suppliers to determine which product fits their needs.

Virtualization also provides small- and medium-sized businesses several key benefits, including lower costs and increased efficiency. According to a report from Quorom Soft, virtualization enhances disaster recover plans for SMBs, backs up critical business data and protects critical systems.
