Local and Domain Administrator password best practice Nathan 05-31-2006

Hi,

This has been mentioned in these groups before but I have never really found
an answer that satisfies me. And I am sure I will get differing answers this
time as well.

Should the Local and Domain Administrator passwords be different?

I have a feeling the answer will be yes.

Thanks

then why ask ;-)

I'd say it was good practice to keep them seperate as administering the
domain and administering workstations (and even servers) are really two
seperate jobs. In big business these tasks would be taken care of by two
totally different groups of people.

As a practical matter, you have to decide how important following this best
practice is for you on a day to day basis depending on the size of the
business you're supporting and your circumstances - I'd not rush to
implement business practices that were designed for the internal networks at
Ford or HP or something like that if your network is a small home business
with 3 computers to its name and actually includes your pet dog in the list
of corporate officers, or if you work in the sort of office where it doesn't
matter how many passwords are set because they're all written down on a
whiteboard by the secretary's desk "just in case someone else needs
them"....

I'm always surprised at "professionals" who STILL have to be asked "Have you
checked (event viewer / syslog)".

All IDs should have different passwords. The builtin admin ID of a
domain in fact should be set to some nasty long (25+) character password
that is impossible to memorize that is then documented and placed in an
envelope and locked in the safe of a high ranking manager. There should
be no reason to use that ID in the domain.

As for Domain Admin IDs, every Domain Admin (all at most 5 of them)
should have their own Admin ID and it should be different from their
normal day to day user ID. So for instance if their normal ID is joe
their admin ID could be $joe. Those passwords of those two accounts
should not even be in sync.

There should be no generic native admin type IDs in use, at best generic
IDs should be limited to services and the permissions should all be
delegated as then you are only giving what you need versus giving them
what they need plus whatever happens to come with the builtin groups.

You caught me by surprise Joe - seems you have become a little
liberal ("no more than five domain admins") perhaps from seeing
client practices in the field.

So, devils advocate here, why five?

I recall when I had to pass adv compiler construction, the prof
observed, as soon as the proc has more than one register it really
does not matter how many there, the complexity of object gen
changes at the one/more-than-one boundary.

It seems to me something similar holds true here. Domain admin
accounts tightly held and used only when/if necessary, or accounts
individually issued to the domain admins (letting the pig out of the
barn).

I case you didn't notice, I miss your prior hard line viewpoint.
It was totally valid. It was also something no one was willing to
say much as it went counter to the mainstream usage. However,
in the long run (meeting today's and tomorrow's auditability,
personal protection, etc.) it will proable become the dominant
approach.

LOL. 3-5 DAs was my usual stance with 3 being the one I felt the best
about. I find people whine less when I say 5 versus 3 though. :)

And when you really really get down to it you don't even need 3 full
time DAs.

I don't agree that the register analogy works here though. I think what
applies with DAs is that the more DAs you have the less each feels
ownership for the environment. In other words, more cooks in the
kitchen, all of them pay less attention and if there is a hair in your
soup you really don't know where it came from. The smaller the DA group,
the more careful each DA would be I think or at least from what I have
experienced.

Consulting has been interesting though I must say... I have gone from
doing support of one of the world's larger deployments with 3 DAs to
seeing lots and lots of deployments and just hoping that these smaller
deployments with only 100k or so users would cut down to less than 100
Domain Admins... Those that listen start running more and more stable
but man is it a fight trying to explain to people they don't need those
rights for most everything they are doing. The usual answer is that
people need them for troubleshooting, and when I say give me specifics
they almost never can give me something that really does require DA.
They give me examples of how they want to change something to see if it
fixes a problem... that isn't troubleshooting.
