Fundamentally I agree with you, security isn't about running the right
OS, etc, we should acknowledge that not all operating systems are the
same. Windows is fabulously complex, with a really large number of
system calls, many of which take a large number of arguments that in
turn change the semantics of the call greatly. Together, these
represent a very large surface area for potential attacks. In turn,
many of the Unix variants are simpler; they may not be any more
secure, but at a minimum, they have less attack surface area. Of
course, it's been my impression over the last couple of decades that
they're trying as hard as they can to fill the gap. To put it in
military terms, the Unix variants have traditionally had more surfaces
and fewer gaps than Windows.
Anyway, this isn't to say that Unix or some variant is inherently more
secure, but all other things being equal, I'd rather put my money on
the simpler thing, since simpler is often easier to get right.
Whether that's really the case or not is another matter; I simply
wanted to point out that there are other arguments beside the flawed,
"security through obscurity" that may come into play when deciding
between operating systems with respect to security.
