I've seen this done before by well-intentioned admins. The truth is, in my
opinion, that what looks good in theory is in reality not a good practice.
No real security gain is accomplished and there are numerous reasons to not
do it this way.

They would be much better off investing in layer 3 switches and a core
router and implementing a strong and secure VLAN architecture with ACL's.
As you say, you could also use the firewall to create an added layer of
protection between the HR VLAN and the rest of the network. You could use
DLP to protect HR files. The net result would be better security and
improved functionality.

Subject: Windows Active Directory Domains

I have a scenario where I am trying to evaluate the security benefits of an
Active Directory domain structure.

We will call the company XYX Inc. They have an AD Forest/Domain for general
users. They also have a separate AD Forest/Domain for their HR Users that is
behind a firewall.

The claim is that the separate forests with a one way trust provides the
necessary security to protect the HR Information.

My thinking is that having the users/servers in the same forest would
provide additional benefit of ease of use for the technical team. Using the
already existing firewall, separate the servers behind the firewall for the
needed protection of HR files.

Before I make a recommendation of one way or the other, I wanted to elicit
the ideas of others who may have seen similar situations.

Thanks

Joe Brown
