IIS 5.0 and
Windows 2000 Hardening Guide
This document is applicable ONLY to Windows 2000 running
IIS 5.0. If any other application is running on the server
to support its function (e.g., Cold Fusion), then that
application must also be secured. The steps in this guide
should be performed on new installations only to avoid
unpredictable results. This hardening procedure should NOT
be used on general-purpose NT servers on an internal LAN
(e.g., file servers), as it removes several of the services
that NT uses for default functionality.
NOTE: You should do all of this with your PC
unplugged from the network. Create a CD with the needed
files.
Instructions
Follow these steps chronologically. You may print this
procedure and check off each of the steps as they are
completed. These steps are not a guide but minimum
requirements for DMZ deployment. Any deviation from this
process may negate the usefulness of the process

Initial OS Configuration
and Installation
|
Check |
Step |
|
| 1.0 |
Boot up Windows 2000
CD-ROM to begin installation and configuration.
|
1.1 The Welcome to Setup screen appears.
Press Enter to continue.
1.2 Click F8 to accept End User License
Agreement (EULA).
Note: Install only one instance of the
operating system. If you need to get on to a server
using another instance, install on need, and delete
afterwards. If there are any previous versions of
operating systems, remove by deleting partitions then
repartition. |
|
| 2.0 |
Choose your OS partition for
installation then choose NTFS for format. Reserve
a separate minimum 4 GB partition for the OS (more
is better). | |
 |
| 3.0 |
Choose regional
settings as appropriate. |
3.1 Type in name and organization.
3.2 Choose Per Seat
License. |
|
| 4.0 |
Choose a name for the
server and set a strong administrator
password. | |

Encryption and Patch
Setup
|
Check |
Step |
|
NOTE: After installing the High Encryption
Pack, it is necessary to run the KEYMIGRT.EXE utility
to upgrade the encryption of the private keys used by
IIS SSL from 40-bit RC4 to 168-bit 3DES (http://www.microsoft.com/technet/security/bulletin/ms00-032.asp).
To obtain the Keymigrt tool, run the patch using
the -x option, to extract the patch contents.
Keymigrt.exe will be one of the files extracted.
10.1 You will now need to
reboot.
|

SSHD for NT Remote Management
OK. Now you need to be able to access this machine
remotely. Here is the OLD port of SSHD for NT we used to
use. I HIGHLY recommend not using this and instead using
SSH.COM's commercial product.
NOTE: There are issues with the cygwin.dll and
separating simultaneous user space. Use with caution!
| Step |
Action |
|
13.0 Download
and unzip sshdnt.zip |
 |
14.0 Run
install.bat
This batch file should do the following:
- Create a server key
- Install SSHD as a service
- Start the sshd service
Note: Check to make sure SSHD is installed
as a service and running. If it is not, refer to
sshd_install.txt for instructions on how to create a
server key and install SSHD as a service.
|
|
15.0 Edit the
passwd file (in c:\etc) to add additional users in this
format:
<Username>:x:<User ID>:<Group
ID>:<Full Name>:<home
directory>:
Example:
- administrator:x:1:10:Local
- administrator:/bin:
|
|
16.0 Using
SCP:
SCP use on NT DMZ host:
- Move file you need to Unix box running sshd
(e.g., host.com)
- Use srt or terra to connect to NT host running
sshd
- Type scp.exe <username>@<hostname with file>:
<filename><path to place file>
Examples:
- To move the file "net.txt" from a Unix host
(e.g., host.com) to the directory /bin on an NT host
running sshd (with IP address 10.0.0.20) do the
following:
- Login to host.com
- scp net.txt administrator@10.0.0.20:/bin
- To pull test.exe from an NT host running sshd
(with IP address 10.0.0.20) to my user directory on
host.com do the following:
- Login to host.com
- scp administrator@10.0.0.20:test.exe
/home/user

client
46.2 Open a cmd.exe (command window), type:
ssh2.exe -L 3389:127.0.0.1:3389 mailto:root@ams-eleads login
as prompted This uses the following
format: ssh2.exe -L [local port]:[full name of remote
host]:[remote port] [username@remote host] [some
command] This will tunnel on the serverside port 3389
to the client side localhost port number 3389.
46.3 Leave the command prompt open and
