Looming large among the management issues that come with nesting Windows instances within the Macs in your care is that of maintaining anti-virus software on those Windows instances. Fortunately (or unfortunately), most organizations have become all too familiar with deploying and managing anti-virus products on their Windows clients, and whether you're tapping virtualization or dual-boot configurations to bring Windows into your Apple hardware, these anti-virus management processes will remain mostly unchanged. Less clear for many organizations is the role that native anti-virus software for OS X instances can or should play. For instance, the PCI DSS (Payment Card Industry Data Security Standard) guidelines through which credit card issuers enforce data protection mandates that anti-virus software must be used on computer systems at merchant sites that are "commonly affected by viruses." The standard goes on to single out Unix-based operating systems-a class of which OS X is a member-as not commonly affected by malware.
However, most of the major players in the anti-virus space do offer OS X versions of their products, including McAfee and Sophos, both of which integrate OS X anti-virus administration into the same management consoles that govern the Windows flavors of their anti-virus products. Symantec, meanwhile, markets a consumer-oriented, "two anti-virus products in one" offering that's meant to provide coverage both for OS X and for the Windows instance that may reside in a Boot Camp configuration. Last fall, Trend Micro and OS X security software company Intego announced a partnership to bring Intego's anti-virus software for OS X to Trend Micro's customers, albeit under separate management interfaces.
