Now with 2009 just past us, it's clear that hackers are exploiting all types of software in record numbers, but it's pretty clear that Microsoft products are still their favorite. This can be seen from the number of patches Microsoft issued during 2009.

Microsoft released in 2009, a total of 72 monthly security patches, including 27 in the first half of the year and 45 in the second half. In addition to that, Microsoft released two emergency security patches at the end of July. For the year, Microsoft released a total of 74 patches - fixing 190 security holes.

Of the 74 patches, 44 were of the critical variety, which is the highest level of Microsoft's patches. In addition, 27 were of the important level, and 3 were middle level. Of the 190 security holes, 132 were classified as high-risk, 53 as serious, and another 5 were moderate.

These patches fixed a total of 157 remote code execution vulnerabilities, 7 denial-of-service vulnerabilities, 7 fraud vulnerabilities, 18 privilege elevation vulnerabilities, and 1 information-disclosure vulnerability.

On the operating system side of things, 34 security holes were found in Windows Server 2003. Three total vulnerabilities were found in the newly released Windows 7. For Web browsers, IE6 had 7 security holes, IE5 and IE7 each had 6. IE8 had the least with 4. For productivity, Office 2003 led the pack with 13, Office XP had 11, Office 2007 had 10, and Office 2000 had the least with 8.

From the data from 2009, we are sure that 2010 will be another big patch year for Microsoft.
