There separate technologies mentioned.

1. Authentication
2. Network segmentation

Active directory is a hierarchy of objects you can "do" stuff with.  You ca=
n apply policies to affect client machines.  You can create groupings of ob=
jects to centralize configuration.  The relationships are hierarchical.  If=
 the account details contained in an OU (Folder) are wished to be kept priv=
ate, then make a different OU parallel to the existing OU.

Then you can restrict the user's ability to search specific OUs: "Anyone in=
 OU=3DCompany, has a search base of OU=3DCompany."  They will never see the=
 OU=3DHR.

HR
-User
-Computer
Company
-User
-Computer

With forethought and design, there isn't a reason to have the two servers i=
n the forest for this scenario.  Additionally the firewall segmentation isn=
't necessary either.  Using NTFS file share permissions will keep users out=
 of sensitive data.  Now there are many variables and 100 different ways to=
 solve any IT problem so by all means this is not the only solution.  Good =
luck, AD is a powerful tool that can help control an environment.

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 ne=
cessary security to protect the HR Information.

My thinking is that having the users/servers in the same forest would provi=
de additional benefit of ease of use for the technical team. Using the alre=
ady existing firewall, separate the servers behind the firewall for the nee=
ded 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
