Where, oh Where, are Perfect Security Features?

In my recent exploration of Windows Vista x64 security features and Patchguard (see pt1 and pt2), one of the issues sent my thoughts in the direction of how “perfect” security feature are (or are not) and how that affected security value to customers. So, here is the scenario.  You read about a new security feature in JeffOS that has been reported to improve security.  Let’s say the feature helps stop exploits of heap overflows.  … Read more »

Windows Vista x64 Security – Pt 1

I recently took home a build of Windows Vista for my home machine, which happens to be a dual processor 64-bit Dell machine, and it made me curious about the differences between the x86 and x64 version of Vista – specifically security differences.    After doing a brief bit of research, I found three unique security benefits in Vista x64: ·  Hardware NX protection on globally by default. ·  Kernel … Read more »

Further Perspectives on Symantec Vista "Research"

Since my original post on last week’s Symantec paper, they’ve released another one as noted by Joris Evers in Symantec continues Vista bug hunt. Now that I’ve read both of the first two papers, I note two perspectives from Symantec on this: 1) the perspective of the researchers in their paper, and 2) the uses that the Symantec marketing team may be attempting with the content.

Now, why I don’t think this applies to my recent vulnerability metrics posts is:   … Read more »
