By most accounts, systems running Microsoft's Windows family of operating systems comprise a significant portion of any given network, private or public. Largely because of this prevalence, Windows has remained a dedicated target of the hacking community since at least 1997, when a researcher named "Hobbit" released a paper on the Common Internet File System (CIFS) and Server Message Block (SMB), the underlying architectures of Windows networking. (You can find a copy of the paper at http://www.insecure.org/stf/cifs.txt.) The steady release of Windows exploits hasn't abated.

Microsoft has diligently patched most of the problems that have arisen and has slowly fortified the Windows lineage with new security-related features as it has matured. Most significantly, with the advent of Windows XP, Microsoft for the first time offered both businesses and consumers a platform based on the NT kernel, which was formerly focused primarily on the needs of the enterprise such as built-in networking support, scalability, fault tolerance, and security. Therefore, we think the common perception of Windows as an insecure platform is simply uninformed. In knowledgeable hands, Windows can be just as secure as any other system, be it based on UNIX, Linux, or any other OS. As an old security saying goes, "The driver bears more responsibility than the car."
