Those looking for simple answers should skip this Computerworld story, which deals with the intricacies of mobile operating system security.
The piece starts with the premise that one of the reasons mobile devices are not suffering the same fate as their desktop counterparts is that they are not subject to the same Microsoft monoculture. The piece quotes a Net Applications figure that 92 percent of desktop OSes are Windows, which has put a long-term and very pronounced target on Microsoft's back. Conversely, the mobile OS landscape is far more varied.
That makes it ironic that at least some companies, according to the piece, may be moving to Windows Mobile. The reasons are that they can't afford separate mobile and desktop infrastructures and want to replicate Microsoft's familiar look and feel on mobile devices.
This raises a raft of interesting, overlapping questions:
Clearly, any discussion of Microsoft and security is loaded. IT departments researching operating systems have to cut through the hype, however, and determine precisely how secure Windows Mobile is, and where it fits into overall security. Part of that research should focus on figuring out the relationship between the desktop and mobile versions of the OSes.
