For five years now Microsoft has been developing this semi-annual report to consolidate their findings relating to malware, vulnerabilities and threats to your computer and online activities.

The Microsoft Security Intelligence Report (SIR) is a comprehensive evaluation of the evolving threat landscape and trends. The information can help you make sound risk-management decisions and identify potential adjustments to
your security posture. Data is received from more than 600 million systems worldwide and internet services.

Significant findings in this report include some good news for those who have moved to Windows 7 or are on its predecessor Windows Vista:

The botnet infection rate for Windows 7 and Windows Vista is significantly lower than that of their desktop predecessor Windows XP, with any service pack installed, which reflects the security improvements that have been made to the more recent versions of Windows. Considering only computers that have had the most recent service pack for their operating systems installed, the infection rate for Windows XP SP3 is twice as high as that of Windows Vista SP2 and more than four times as high as that of the release-to-manufacturing (RTM) version of Windows 7.


The key areas that version 9 focuses on are:

  • Featured Intelligence for Volume 9 focuses on botnets and how to combat the threat.
  • Key Findings reveals data and trends analysis captured by Microsoft security analysts.
  • Reference Guide provides definitions for discussion points covered in the Key Findings.
  • Managing Risk recommends techniques to protect your organization, software, and people.
  • Global Threat Assessment looks at botnet and malware infection rates worldwide.
