It's funny cause someone posted this in an earlier thread. . .

I don't want to sound like a zealot, but I do prefer to stick to
reproduceable data and not just popular opinion. Win2k outta the box
has as many holes (5) as Solaris 6 (5). After the latest security patch
on each platform, Win2k had 3 holes and Solaris 6 had 4. Win2k outta
the box only has 1 more "hole" than Sun's recently launched Solaris 9 on
its default install.

I don't know what the severity of these holes are, but those are the
numbers as these guys posted them.

I agree with Vasiliy Boulytchev said in his last email, but, im sure he
knows what im about to say.

Just because you switch to "linux or a openbsd" from windows, doesnt
mean your "secure" right out of the box. Thats a total LIE, and I would
hate to see people being mislead.

Every operating system has its insecurities.
I dont care what OS it maybe. I would say "Windows" is a last choice for
a secure OS out of the box.

All I can say is your OS will be as secure as the administrator is.

Just my 2cents.

Stay Safe!~

    Forget Microsoft's suggestions about staying secure. Scratch the
costs of MS ISA server, or whatever they call that junk these days, and
install Mandrake, Suse, Red Hat :( , anything but winblows. I know
FreeBSD/OpenBSD blows tux out of the water, but you should start at
something simpler. Regards, Vasiliy Boulytchev Colorado Information
