TechTarget reports: "When Vista was released to manufacturing,
Microsoft co-president Jim Allchin told the press that the number one
reason for upgrading to Vista is that it's far more secure than
previous versions of Windows operating systems. In the year since
Microsoft released Windows Vista to corporations, and just under a
year since the OS was released to consumers, Vista's new security
features have drawn both praise and criticism. In this article, I take
an objective look at security features that seem to be drawing the
most attention."

This a good article that talks about some of Windows Vista security
features (User Account Control [UAC], Windows Security Center, and
Windows Defender). I like this article because it seems balanced in
the opinions that are expressed.
