RE: IIS6 Security and other web servers

["Roger A. Grimes" <roger () banneretcs com>]

Randy,

Any Internet-facing server without intervening layers of defense sounds
risky to me...no matter who is the vendor.

However, my www.hackiis.com contest coming in April will test just the
point you made...how secure is it by itself.

Greetings All,

I'd like to ask for some clarification here.  I know that Ebay,
Anandtech, et al. run on a purely Windows architecture (for the ease of
programming in .Net from what the folks at Anandtech are saying) for
their web-services and that works well for them.

However, I know of no Windows architecture that is exposed directly to
the Internet.  Every vendor/consultant/Admin I have ever met is saying
that in order for Windows to be secure it must be protected by layers of
protection (hardened router, hardware firewall, etc).

On the other hand, I know of a number of LAMP-type servers that are
exposed directly to the Internet with no intervening layers.

Am I to take the statement that "IIS6 is a very secure platform" to mean
that IIS6 is only secure after it has been hardened from its insecure
default installation and protected by layered security that prevents
direct access to the Internet".

I may well be wrong here, so please feel free to correct me if I'm out
on a limb.

Thank you,

RandyW
