Top 12 Operating Systems Vulnerability Survey

Also posted yesterday on Slashdot:

Have you ever wondered how vulnerable your computer is from the first bit you write to the hard drive all the way until you have a fully patched system? If so, Matthew Vea has posted a concise summary of security strengths and shortcomings for twelve of the major operating systems of 2006/2007. In his summary, Matt tests each OS with widely available tools like nmap and Nessus, and notes responses at install, pre-patch, and post-patch times for each system. After the tedious job is done, he produces results that will make both the Apple and Windows communities cringe with regards to security. From the article: 'As far as straight-out-of-box conditions go, both Microsoft's Windows and Apple's OS X are ripe with remotely accessible vulnerabilities ... The UNIX and Linux variants present a much more robust exterior to the outside. Even when the pre-configured server binaries are enabled, each [Linux] system generally maintained its integrity against remote attacks.'

A lengthy but fascinating read. They did include Vista in the roundup as well as Mac OS Classic (as opposed to OSX which is FreeBSD-based). Also tested were Fedora Core 6 and the most recent Ubuntu 6.10 version. For those of you unwilling to read through all the technical info, here's the nutshell conclusion:

When it comes to business, most systems have the benefit of trained administrators and IT departments to properly patch and configure the operating systems and their corresponding services. Things are different with home computers. The esoteric nature of the UNIX and Linux systems tend to result in home users with an increased understanding of security concerns. An already "hardened" operating system therefore has the benefit of a knowledgeable user base. The more consumer oriented operating systems made by Microsoft and Apple are each hardened in their own right. As soon as users begin to arbitrarily enable remote services or fiddle with the default configurations, the systems quickly become open to intrusion. Without a diligence for applying the appropriate patches or enabling automatic updates, owners of Windows and OS X systems are the most susceptible to quick and thorough remote violations by hackers.
