Recently I found a news about an analysis elaborated Secunia (which is an IT security company) that indicated that in 2007 Mac OS X it presided over the list of serious vulnerabilities, surpassing with ample margin to Windows XP and Vista.
This year, Secunia has registered a total of 237 critic vulnerabilities in Mac OS X, versus 23 found in Windows XP and Vista.
In general, the Macintosh platform is considered like safer than Windows. Nevertheless, the statistics demonstrate in opposition to the detected more than five vulnerabilities in that platform than in Windows.
This does not mean, necessarily, that Mac OS X is more unsecure than Windows. According to Apple, the new version Leopard (10.5) incorporates greater mechanisms of security than the previous versions. Until now there are relatively few examples of code designed specifically to attack the Macintosh platform, whereas malware for Windows much more is propagated.
Indeed the fact that the Macintosh platform does not have the same degree of penetration that Windows implies that there is less interest to write malware specific for Mac. The conclusion seems to be that with this level of vulnerability, the Macintosh platform would be highly uncertain if it had the same number of users as Windows.
