Slow day on ML!

Trying to wrap my brain around adding a CA to our domain so we can encrypt traffic between servers. OMG... Where do I start....

For AD, I assume?

Yes sir. What brought it about was we run Citrix xenapp and nothing is encrypted this side of the ADC

Well, the passwords are. That's the only important bit in a typical domain communications chain. Not to belittle "encrypt everything", because that's a good idea in general. Just saying that AD is decently secure even when at its least secure.

@scottalanmiller
I just asked the reason behind it and "Mind Blown" because we have a consultant that is working on stuff already and is willing to do it. Along with it being best practice. So now comes the fun, learning how not to break it.
This was not a "Norm" response to my question.

Set the Certificates for as long as your CA will allow, lol.

AD (and everything using it) is only as secure as the DC.

DCs are pretty secure unless you screw something up. However, the DC does not hold passwords, so even a compromised DC does not divulge passwords. So technically, it can be more secure than the DC

Leaving work because its now Margarita time!

That's the thing, if you compromise a DC, you don't need any passwords... There was a whole session on this that I have been to.

Counting down til I leave Sunday Evening for KC MO with a few friends.
Taking some time off work to go enjoy myself at a concert. -

Depends on how you compromise it. What can someone do if they only have the data from the DC?

Well they can push things out from GPO, I guess.

They can access any data on any Domain PC.

One of the simplest things to do for a DC is enable BitLocker, especially if it's virtualized. Encrypting the data at rest on a virtual disk is essential.

This is the session i attended... well, the session's slides, which doens't say mcuh at all... but it's a breadcrumb:

But what's the real world attack vector? I'm not saying that a DC is impervious or anything. I say all the time that AD adds a lot of risk, there is just so much more to fail.
But their attacks seem to be focused on big, offline attacks where they are getting a copy of your drive (physical theft let's say) and you don't change your passwords, and they have lots of time to brute force them.
While that's a real risk, it's a really unlikely one. There are so many steps needed one the attackers side to make it work, and so many ways to protects on the other side, even after the attack has begun.

That's one way. If you compromise any domain joined PC, you can likely move laterally, it may be possible to compromise everything.
It all depends of course. AD and AD domains can be very secure, but they can also be their own major vulnerability if not properly secured.
