Do you think there are security benefits businesses could reap by simply switching to open source solutions?

Greenberg: Yes. A great number of security holes are because of Windows having glaring security holes in its browser and mail agent. Use Windows and Firefox, for example, instead of Windows and IE, and 80 percent of the security concerns vanish. The number of security threats in an OS-to-OS face off is about equal, from what I see. As — and if — Linux usage increases, the Linux threat level may increase.

Let's assume that to date an organization has used primarily or only Windows and other proprietary solutions. Would you offer some suggestions as to how such an organization could evaluate the security merits of a Linux distribution?
