The sheer number of desktops, laptops, and servers running Windows makes them an easy and readily available target for malware writers and spammers. Assessment of an organization's requirements for protection against viruses, spy-ware, Trojans, and worms has therefore tended to concentrate on the Windows environment. Meanwhile, the current risk to computers running non-Windows platforms is small but growing. As Mac and Linux computers become more prevalent within organizations, they are likely to become more of a target for hackers as a way in to the rest of the network and a means of infecting websites. Read this whitepaper to learn more about the real threat from non-Windows platforms, the dangers of their distributing Windows viruses, the implications of their growing popularity, and the regulatory pressure to protect them.
