Here's a post from Michael Calore on Wired's Blog Network about a new report on Microsoft Vista's security performance. In the system's first year of availability, the report says, Vista had fewer vulnerability issues than several other (Microsoft and non-MS) operating systems required in their first years. Here's the punchline: the report was cooked up and issued by Microsoft's security team.
GTO would like to point out that part of the steel-trap security on Vista could be based on the fact that everyone has refused to use it. How do you keep an OS invulnerable? Make sure it never finds its way onto a computer. Looks like Microsoft finally figured it out.
