Just like cops don't actually Enforce the law, they simply report law breakers to the Court, and a Jury and Judge then validate the claim and punish the law breaker.
You're the cop, you see and report, you don't enforce.
Arresting someone doesn't mean you're enforcing the law, it means you're taking someone in to be judged by those who's job it is to enforce the law and pass punishment.
In this case I'm being asked to install the vault door on the vault - i.e. the technical implementation. Not simply the security guard.

On the technical aspect of the request it should be easy to enforce in an Microsoft AD Enviroment as below:

https://docs.microsoft.com/en-us/previous-versions/dotnet/articles/bb530324(v=msdn.10)#grouppolicydeviceinstall_topic3cThe challenge is on Mac with FireVault. I will look into what I have with Sophos as I use them for this. However you policy should be enough.
While i agree that a policy SHOULD be enough - they specifically said - technical.
FYI - No AD in this environment.

I also would think they want your devices in the office to be Encrypted at a minimum as well.
You know - you would think, but they haven't breathed a word on that...

Because they don't know about it, so just keep quite on it.

@Dashrender you are really starting to sound like @WrCombs when he's asking what he should do about policy.
It's not your problem to enforce the policy if people circumvent it, it's your job to simply follow and report violations and maybe even draft a workable policy that HR can enforce.
Edited in bold.
You're assuming that a policy is simply good enough for the insurance company... if they come back with Product X satisfies the technical requirements, then clearly, policy alone does not solve the problem to their requirements.
So I am thinking they have a technical requirement hence why you are asking right?
yeah - I quoted it above... they basically said - policy is not good enough - we want to see a technical solution.

You can still enforce via local group policy for Windows.

I also want to see Unicorns and Flying Dragons in the world, doesn't mean such a tool exists or works in a way that would be good for your business.
Just like Unicorns and Flying Dragons may exist in one form, but certainly aren't what many people think about when you say this is my unicorn or see the flying dragon.

yep... though I would/should use something like Salt or some other agent based solution to push out changes for this if for no other reason than consistency.

You would have no way to do this.
You can setup encrypted volumes on USB drives you control, but there would be know way to do this for every USB drive.
This is my initial reaction too.. but I'm trying to turn over a new leaf, and say 'yes.' which in this case starts with researching possible solutions.
I'm wondering if there is some type of MDM/end user device management (something like Intune).
How would it encrypt the drive? That would mean it would realistically ransomware people's devices if they mistakenly plug a personal USB into a work computer.
I think the only option is blocking unencrypted drives. But it wouldn't be encrypted versus not, it would be encrypted by a certain tool or not. That's about the only possible solution.
So the issue here is with the Apple computers, that unless you are granting the user administrative rights, they wouldn't be able to mount the drive, and thus the encrypted data would remain encrypted.
So how would the computer (windows or otherwise) know "what tool was used". This is a schrodinger's cat scenario. You can't know that the data is encrypted, without first opening it up and checking. Which if the computer can just open everything up than it knows how to decrypt every disk and volume that may come in contact with said system.
Which essentially means a backdoor so your users can't go dark.

And while we haven't given them our current policy - i.e. so they couldn't have read it and said - it's not good enough... we just told them, we have a company policy... so if company policy was good enough - I would expect them to say - hey, before we sign off on that company policy, we need to see what it says.. then I would agree that going Dustin's route would make sense
Right, and my point is that you need a mechanism, not just a policy, to make them happy. But I think that that could be done.
no mechanism is going to keep crazy users from just picking up random USB sticks and plugging them.
Sure it is, all kinds of mechanisms can prevent that. Nothing prevents anything 100%, but lots of things prevent some. And that's all any requirement is asking for.

So if you know this, then why did you say I was delusional for thinking that if you updated and enforced your policy would you be good?
because a policy is not a technical solution.. a policy doesn't stop the crazy person from plugging a drive.
Right, changing the policy is to remove the need for a non-viable technical solution so that the policy you write has a viable technical solution.

@Dashrender said in Force USB encryption Windows and Mac:
only a technical solution prevents the computer from accessing a non authorized drive.
No, nothing completely prevents it. Technical solutions and policies both partially prevent in, in different ways.
-
@Dashrender said in Force USB encryption Windows and Mac:
Sure I can fire them... AFTER they plug the drive into our computers - but that's to late.
But not related to the problem. So you should not mention this because it's not relevant. This is an additional policy. Fine to have, but not part of the blocking / preventing policy, nor a part of the technical preventative.
-
@Dashrender said in Force USB encryption Windows and Mac:
Did you see what you just wrote? WHEN I PURCHASE... what about when crazy person purchases? and brings from home?
You are doing "what ifs". Remember, we've covered and you agreed, that there is a workaround to every possible technical measure. So that you can find a way to work around any specific one is not relevant. Technical measures are not full proof, and don't need to be.

Almost. But in this case the insurance company is asking him to enforce as well. But enforce doesn't mean 100%. Cops don't enforce the speed limit 100%, but that doesn't mean that they don't enforce it.

Sure, but you can blast through a vault door. It's not perfect. It's not even close. It just discourages the behaviour.
Same with other things you can do like providing the USB sticks, confiscating rogue sticks when found, etc.

You would not think unless there was a policy about it mentioned to them. If there wasn't, you'd not expect it. Remember, none of this is about encryption, it is all about enforcement of policy. That this case is encryption is a red herring.

The cops don't enforce, they ticket people, as a means of getting that person in front of a judge who then validates and punishes.
Judges are enforcement, cops simply act as witnesses to an act.
