Windows 2003 Small Business Server & IIS Security

| David Wang on 12/03/03 in this forum gave an excellent blueprint on securing
IIS 6.0 in Windows 2003 Small Business Server (SBS). He, and others, said it
is a bad idea to idea to host Public Web Sites on SBS.
So my question is: What would be the network
configuration/settings/blueprint for having the Public Web Sites on another
computer (with Web Server 2003 separate license)? The Sites need to be
updated/maintained by some client workstation of SBS.

| I'm not exactly sure what you're asking, since you're answering it in your
post as well.
So you'd have:
SBS (which is also a DC) and your internal Exchange/SPS site running on that
computer, then your Windows Server 2003 machine(s) joined as members to the
SBS domain, and you don't need any extra CALs, because the SBS CALs cover
the whole SBS domain

| Would not Web Server being on the internal side of SBS firewall be a
security breach?
What is the network topology for the Web Server to connect to the internet
and SBS domain?
I don't fully understand the practicalities of setting up a DMZ and,
everytime I read about it,
I see 4-5 options in topologies.
Thanks,
Robert

Robert,
If you must host a public-facing web site on your network then don't
make the IIS server a member of your domain. That way if the server
does get compromised you limit the privilege that any attacker might
gain.
However, this is still a less than ideal situation. Ideally, you
should either implement a DMZ or if you aren't confident with that
then look into using a co-located hosting solution. There are some
quite cheap co-lo deals out there.
There's some very useful security information here :

| Thanks.
If the IIS Server is a standalone Workgroup (not domain member) with an NIC
connection
to an SBS CLIENT (with two NICs), then (with right ID/password), then I can
connect from
that client to IIS for updates? In other words, can a Domain member connect
to a Wrokgroup member?
I can even disable the 2nd NIC on the CLIENT when not updating.
How well would this configuration work with TWO dedicate IPs assigned by my
ISP.
1. www.MyCompany.com points to Dedicated_IP_Address1 which connects to SBS
(thru a Linksys firewall for a little extra protection) with SBS locked down
for just approved company access as suggested by many here.
2. www.PublicWeb.com points to Dedicated_IP_Address2 which connects to Web
Server 2003 thru Sonicwall SOHO firewall (automatically blocks Denial of
Service attacks such as Ping of Death, SYN Flood, LAND Attack
and IP Spoofing, etc). [This has worked well for a year.]
3. Web Server 2003 has a second internal NIC connecting to SBS so the Web
Site can be updated.
4. SBS rules/features/etc are used to limit what can be done from Web Server
2003 on the SBS Domain.
Thanks again!
Robert

Hi Robert,
Yes, you could update the content on the standalone web server using
FTP. Just create a local user account and point that user's home ftp
folder at the root of the web content folders and you're set. Don't
forget to disallow anonymous ftp though.
For maximum security you could even consider removing the second
internal NIC from the www.PublicWeb.com server and just connect to it
via the internet when you want to update its content.
I would also consider moving the www.mycompany.com site and IP address
to the standalone box - unless of course you are using it for OWA.

Paul Lynch

| Hi,
The decision is really up to you. You can have it on either side. As Paul
said, you may not want it joined to the domain at all. If you have some
sort of firewall before the SBS box than I wouldn't put the web server
behind SBS
