"There's a race between attackers and defenders and if we want to win, we have to share information," said Mike Reavey, director of the Microsoft Security Response Center.
To help realize that goal, Microsoft plans to release the Microsoft Office Visualization Tool, which provides a graphic visualization of the Office binary file format. The software is intended to help IT professionals and security researchers better understand attacks targeting Office files.
The reason for this is that most malware attacks application vulnerabilities rather than operating system vulnerabilities. In the second half of 2008, said Reavey, almost 90% of the vulnerabilities were in the application stack rather than the operating system.
"In order to build protections, you have to understand how a specific file format is meant to be used, so then you can understand how it's being misused," he said.
Microsoft also plans to release Project Quant, an online information resource that aims to provide organizations with a framework for evaluating the cost of patch management processes. According to a survey conduct as part of the project, nearly 50% of respondents had no patch management process for desktop application software or had an informal process.
In addition, Microsoft intends to release the Microsoft Security Update Guide, a publication that explains the entire Microsoft security update process. "Finding good guidance if you're a customer in the sea of information is challenge," said Reavey. "We wanted to provide a guidebook. By sharing how we manage risk, we hope we can help our customers manage risk."
Finally, Microsoft expects to publish a report titled, "Building a Safer, More Trusted Internet Through Information Sharing," which summarizes the three security programs launched at Black Hat 2008.
The three programs are: Microsoft Active Protections Program (MAPP), which supplies vulnerability information to security partners prior to the release of Microsoft's security patches; the Microsoft Exploitability Index, which aims to quantize the risk of vulnerabilities to aid patch prioritization; and Microsoft Vulnerability Research, which helps third-party vendors make their Windows applications more secure.
MAPP, the report claims, has helped Sourcefire reduce the amount of time it takes to build exploit detection for a vulnerability from an average of eight hours to two hours. The report also notes that the Microsoft Vulnerability Index has proven to be 99% reliable, a sufficiently high rate for Microsoft to declare the program a success. And as for Microsoft Vulnerability Research, the report says that the program has identified software vulnerabilities affecting 32 vendors.
Information sharing, the report concludes, is critical to making the Internet safer.
