Re: IIS6 Security and other web servers

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

Internet-exposed companies in the world run it. Ebay runs it. Like any
web server, you must follow basic guidelines and keep your patches
up-to-date, but that is any product.

If you have mostly Windows experience, it certainly isn't a poor choice.
Anyone saying otherwise is just going on inaccurate or old data, or just
letting their personal preferences get involved.  I use both IIS and
Apache, and both are secure when implemented as recommended. I'm a
Windows guy, though, so configuring security and other things is easier
for me in IIS (click, click, click) than in Apache (find text file to
edit...).

In fact, Windows IT Pro mag and I are sponsoring a Hack IIS contest in a
few months with prizes.

Dear friends,

I just want to throw a little question to know your opinion.
I was discussing yesterday with a friend about the quality of IIS6 from
a Security point of view.
He immediately said it's a bad choice, as previous Microsoft web
servers.
I've read a few papers and I have this opinion: as it's been redesigned
from the ground (with all the previous failures in mind), with the
security perspective, with every little service and option disabled by
default, and so on, I told him that now, in my opinion, IIS6 is a good
choice.
He loves GNU, Linux, and, logically, he thinks Apache is the king in
security.
Just because I felt curious, I went into www.securityfocus.com to check
the latest vulnerability advisories, for Apache and IIS6. Incredible,
Apache wins, it has many more (not to talk about the many releases since
version 2.0)! In fact, I just found one alert about IIS6.

What do you experts think?
Of course, I know IIS was very dangerous before version 6.
But, maybe an IIS6 in a well configured, patched and securized Windows
2003 machine is al last a good choice to house Web Applications?
Or maybe it's too soon, there are few installed, and maybe in the future
it'll have as many holes as the predecessors?

What do you think?

best regards from Spain,

DAVID
