Description :
Researchers Chris Valasek (Senior Security Researcher at Coverity) and Tarjei Mandt (senior vulnerability researcher at Azimuth Security) spend their days seeking ways to compromise security in Windows. They're good guys; if they find a problem they report it, rather than exploiting it for illicit gain. At the Black Hat conference they reported on their analysis of new low-level security features in Windows 8.
The precise details of what they discovered were barely within the realm of my comprehension. Apparently many doubly-linked lists within Windows 8 are now protected by "pool cookies." To avoid exploits that involve forcing arbitrary code or data into places it doesn't belong, Windows 8 randomizes locations for memory allocation and adds "guard pages" as needed. That sort of thing.
In between slides filled with code and intense details, Valasek and Mandt displayed a couple that anybody could understand. The column for Windows Vista was all red, meaning not secure. Windows 7 was close, with just a few green checkmarks. And of course Windows 8 displayed a column of solid green checkmarks. Expert or not, we know that green is good.
Whether secure or not just hope we do not see this message often while using Windows 8. Comment and let us know what do you think about this article.
