@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.

@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.
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.

@DustinB3403 said in Force USB encryption Windows and Mac:
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.
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.

@dbeato said in Force USB encryption Windows and Mac:
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...
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.

No, they arrest. They physically remove people from vehicles. I've had friends had it done to them. They put rumble strips on the road, spikes, all kinds of enforcement items.

Judges are punishment, not enforcement.

that's why "law enforcement" is a reference to police, not judges or juries.

Items to get the person in front of a judge and jury who actually punishes the person.
You can be detained for a while by a cop, that isn't punishment.

@scottalanmiller said in Force USB encryption Windows and Mac:

Law enforcement generally, yes but the practical explanation is that the police are there to bring people they suspect of a crime to justice to be judged.
-
@DustinB3403 said in Force USB encryption Windows and Mac:

No amount of punishment is enforcement. No matter how severe. The law is already broken.
Enforcement only can exist if before the act happens or is completed.
-
@DustinB3403 said in Force USB encryption Windows and Mac:

Correct. Detainment is stopping whatever from completing, hence enforcement. Anything with the term "punishment" in it can't be enforcement.
It is enforcement, not punishment, of concern to the insurnace company in this case.

Correct. Cops enforce, judges punish. That's the universal explanation. One is to stop a transaction, one is to exact revenge.

This really doesn't seem hard. The insurance agency seems to just want some mechanisms to make breaking policy harder. From GPOs, to glue in the USB ports, to confiscating rogue devices.
The computer itself can't do the checking as Dustin pointed out, it has to mount and use the drive before it can know, so the computer has to be "after the fact". The computer can complain about what you've done, but it can't enforce. it's like a judge, not like a cop.
Any "cop enforcement" mechanism has to be before the USB goes into the computer or at least before the port is enabled.
-
@scottalanmiller that I can agree with.
This is all pre-device connection. There is no realistic way to prevent breaking the policy. Because users...

No way to absolutely stop them, no. But there are reasonable "technical solutions" to make it less likely. From confiscating rogue drives to disabling ports unless enabled on a use by use basis.

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/windows/it-pro/windows-server-2012-R2-and-2012/jj679890(v=ws.11).
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.
You can still enforce via local group policy for Windows.
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.
We did it with USB drives that are encrypted on the drive. So you could mix those two. I have one of these personally:
https://www.amazon.com/Corsair-CMFPLA3B-16GB-Padlock-Flash-Drive/dp/B06XNQH822/ref=dp_ob_title_ce
But there are a ton of options like that. The company bought FIPS 140-2 compliant ones, you can decide that or not.Keep in mind this was what I did for Linux, not sure what the Windows guys did. But what I did was leverage USBGuard and when we handed out an encrypted drive we added it to the drive list that was pushed out to all of the systems. Only those USB devices were able to be used on the systems.
However @dbeato pointed this out earlier and you could most likely do the same thing. I just don't know how to add the USB device serial number in Windows (if it was Fedora or RHEL I'd love to help you lol).

I do know they also used Kingston DataTravelers. So if you didn't want to have to type the pin on the USB drive, you could just plug that model in and there was a small piece of software that ran and you could type in the password. It worked on both Linux and Windows.
Here's the link to the Kingston site with the encrypted ones:
