Local Guest Account



  • Are you guys disabling or deleting your local guest account on servers?



  • We disable it.



  • @DustinB3403 said in Local Guest Account:

    We disable it.

    According to Microsoft that is a low risk and if you aren't getting alerts for local user account changes it can pose a much higher risk.

    The local admin account is generally changed on a regular basis, but guest accounts are rarely touched. An admin or even a vendor could in turn enable the guest account and give it local admin privileges, and chances are you would never know.



  • So your question was semi-rhetorical?

    He didn't ask what he SHOULD do, only wondering what we DO do.

    I was curious on how it was being addressed by others and I figured I would share what I learned.



  • So deleting should just be what we do.

    Yes, in order to be 100% sure that local elevation does not happen. Unless you are actively monitoring local accounts which most organizations do not and only monitor domain accounts.

    Wait, you allow Vendors access to your servers without monitoring them to see what they're actually doing?

    Internal IT poses a risk as well.

    Having a computer poses a risk. We should just kill all these risks, and kill all computers.

    Depends who you work with...I trust all my team I work with. If I didn't, I wouldn't work with them...

    You pay people to do work but stand around watching over their shoulders? That's bad practice. If you don't trust them, why are they on the machine with access to things you don't trust them to touch?

    Right, so why watch your vendor like that, they are part of your team.

    They weren't the problem. The problem was whoever gave them tons and tons more access than they were supposed to have. Why were they given open access to the network? It was the network admin's lack of security that caused the problem.

    Not always, we are told by clients to allow some vendors onto their systems, they were never recommended by us, therefore not part of our team, they're an external third party. Not saying sit there and just do that, but we are always on the server at the same time with a recorded session in those instances, can still do other tickets etc in the background, but keep an eye on for opening stuff they shouldn't be doing/have a recording to prove stuff that was done etc

    In that case the client is the system administrator in charge of security and you are peers on the team with the vendor. Still part of the team, and you're not running IT. The IT manager is the one making the security decisions.

    You can give yourself a local admin rights in about 60 seconds through the GUI. If you script it, you are talking about 3-5 seconds. If you are going to let someone on your system, you better be auditing them.

    That was my point, we do that, we record everything as well to make sure we don't miss anything/can play back and see exactly what was done, covering ourselves in case something they do breaks the system//creates a backdoor//loophole like this
