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.
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.

There's a lot more to it, but it was a while ago I attended and no longer remember enough details to keep going... but I remember the take-aways. I'm sure there's a lot about it around, but I can't look atm.

RojoLoco's audio tip of the week: if you want to add some serious bass to your home theater or music system, get a powered sub from monoprice. I got the 12" one for $100.... The thing is a beast. Tight and accurate too, on a variety of genres of music. Highest recommendation.

Party day around here. Been partying for hours already.

Just finished the first week's training session for the DevOps course at cloudskills.io.
It was fantastic!

Catching up on some E-mail / comments from YouTube videos.
