RE: software to control domain administrators

I agree whole heartedly about checks and balances, but that was not the question posed.
 
The question that was posed was, 
 
"Does anyone know any software to control, audit, or restrict access or privileges to domain administrators."

The "If I can't trust my admin he/she shouldn't be one" is not an archaic thought, it is a reality of computing.  This 
is totally different from granting a user a higher level of permissions to do their work.
 
In your case of granting sudo aka for win32,  runas access to a user or junior admin, that is great, should be done and 
is a standard in modern networked enviorments.  But again, we are not talking about limiting that persons access, we 
are talking about "YOUR" access, the domain admin, the person who gave the junior admin those rights in the first place.
 
There is no such beast as a domain admin account without domain admin rights, it does not exist.  It's like trying to 
restrict root on *nix.  root is god over *nix, the same way a domain admin is godlike over windows (i use godlike 
because the juciest account is the all powerful system account)
 
BTW, Granting a user the necessary rights to do their job with the most restrictive set possible is by no means a new 
school of thought.  It is quite old.

Full domain and
enterprise administrators are less and less common in favor of dividing
responsibility so administrators can have less rights to perform their
day to day functions.

Well, Someone has to got to be in that position, the enterprise just does not manage itself.  And that is the person 
that we are talking about restricting.  I have a feeling that your definition of an administrator is much different 
then mine.  I am talking formal Network Administrators, not joe blow end users promoted to a network admin position 
because they are the most computer savvy.

I will restate my mantra differently,  If you can not trust someone to be in a position of complete un-adulterated 
control of your network, then they should not be in that position.
 
Audit, Audit, Audit, Audit.

"If I can't trust my admin he/she shouldn't be one" is an archaic school
of thought. In today's age of compliance and accountability that school
of thought needs to be radically changed. There needs to be checks and
balances. Which is why security has to be separate from operations. More
and more enterprises are following the new school of thought that an
employee has the computer access and permissions that it takes for he or
she to perform their functions no more no less. Full domain and
enterprise administrators are less and less common in favor of dividing
responsibility so administrators can have less rights to perform their
day to day functions. Windows offers runas and sudo capabilities which
we utilize to reduce the number of people who require administrative
access.  I advocate a central/separate syslog/event viewer server that
is not in the domain and the administrators have no access to
whatsoever. Now if someone is trying to cover their tracks they can't
because the logs are duplicated in real time to the central server. It
should be stressed it is not a matter of trust but a matter of checks
and balances.

First, Always **Audit Everything**......  I was not advocating 'not
auditing'.

Trustworthy Admins already do this with the explicit knowledge that they
themselves are subject to being audited and that their actions on the
network will be logged.  The point I was attempting to make before is
that a malicious admin or one that feels threatened has the power to
reverse that auditing, which the auditing mechanism should reflect
anyways. But the problem is compounded if the admin has access to the
logs, then there is nothing stopping them from covering their tracks.

I apologize if it confused anyone.   The overall theme remains the same,
if you can't explicitly trust the people who are running your network
then they should not be running it.

Probably a little late, been busy, but I did not see a response yet to
this.

(assuming we are talking about NT/AD Domain Admins)

Honestly, if you are looking for something to audit domain admins, then
you have bigger problems.

Domain admins by the very nature of the account type, have complete
control over the domain, second to only enterprise admins.   Nothing you
install or do will prevent them from removing or modifying it.  Even
restricting them via NTFS permissions or GPO's does nothing since they
can just take ownership and modify the permissions.

Keep in mind that spying on a domain admin can have catastrophic effects
if they feel threatened by it since they can easily mess up an entire
network.

Basically, If you can not trust your domain admin(s), then they should
probably not be a domain admin and removed from that position of trust.
