Microsoft Security Threat Research
One of the things you need to do to keep your software safe is to be aware of trends and vulnerabilities that are currently being exploited by attackers.
Today I followed a link to the Microsoft Malware Protection Center from one of my friends on Twitter. Excellent find. This is a fantastic resource with tons of good information. (I've been out of the security business for way too long.)
The Microsoft Security Intelligence Report (SIR) provides an in-depth perspective on the changing threat landscape including software vulnerability disclosures and exploits, malicious software (malware), and potentially unwanted software. Using data derived from hundreds of millions of Windows users, and some of the busiest online services on the Internet, this report also provides a detailed analysis of the threat landscape and the changing face of threats and countermeasures and includes updated data on privacy and breach notifications.
