Local Encryption ... Why Not?
-
Remember HIPAA is about one thing and one thing only: covering your ass. It is not about actual security, it is not about specific tasks. It is all about doing things to cover your and your company's collective butts. Being more secure but carrying liability is very foolish compared to being less secure and shedding responsibility.

Goal: Print Labels
Solution: Pull data from the service to print labels. Why do you need all data pulled down locally to do that? If I am using an application like Spiceworks I don't need to do that. If I am using excel I don't need to do that. Sure, some apps don't work well for this, but that is what we are potentially looking to address, right?
We happen to use Sharefile for Healthcare for our PHI transfer.
I'd have to get the file from there to Excel somehow.
Well then consider switching to more practical applications that help to meet HIPAA and PHI security needs.

Are you sure?
Judge: "If the system was secure, why was it encrypted?"
You: "Just in case our users started storing data locally."
Judge: "And you don't feel that encrypting the drive suggests that you support that action and enable it by making it seem like you intend for them to put PHI there?"
You: "Ummm... but I didn't tell them to put it there." -

We had an employee who lost their iPad. But we set them to erase after 10 tries. So while there is some chance that another person who found the iPad could have guessed their passcode (hoping it wasn't 1234), but the odds are the iPad got erased. The chance drops even more if they use a real password. Which of course they will hate, so there's that tradeoff.
You are assuming that this is someone after the hardware, not the data. If someone was after the data, they would disassemble the iPad and your data is probably compromised.

We were discussing that the other day. If the data on the drive itself in encrypted.
Did we ever come to a conclusion?

Me: Yes, that is why we installed a self-encrypting drive. As you know, sir, drives with this technology that are lost are not considered breaches.
Judge: Oh, that's right. Thank you and have a nice day! -

Then pulling the drive wouldn't help them, right?

My theoretical conversation is much better. LOL.

Here is an article from a very large healthcare organization in NJ.
http://www.inforisktoday.com/interviews/shifting-to-hardware-based-encryption-i-987/op-1
Some key points:
- they are doing this on 800 laptops
- he mentions about not having to report breaches on drives with encryption if they can demonstrate there is no exposure or potential exposure
- he says there is no way to guarantee users are not putting PHI on the laptops
I know in a previous thread it was stated that this is technically data theft, but that still doesn't protect them if a laptop is stolen and they can't without a doubt prove there is no PHI on it.
This goes back to my original question. Instead of trying to force the hand of people to store stuff in the cloud, or not download PHI, or any of those things ... why not just force them to use complex passwords and encrypt the laptop?
-
My other question remains:
You have a doctor with a small practice. He comes to you, fresh off a seminar where he was told all his data at rest needs to be encrypted, and wants you to do that.
Are you saying you'd tell him you don't recommend it?
In the "judge" scenario how could that be anything but negligence? We know it is required as IT people. (Unless you want to argue that PHI doesn't need to be encrypted at rest. Is that a gray area of HIPAA? (Of which I agree the whole thing is a non-checkbox grey area.)) The doctor has been informed. How could either of you answer anything but you know it should have been?
-
The law does not require PHI to be encrypted at rest.... only highly recommended by the OCR, not the law.

Yes, but if you don't, you'd better have a good reason why not.
"Because the staff didn't want to use passwords" is not going to cut it, I don't think!
This is a good blurb that kind of backs my feelings on this:
You’re required to encrypt PHI in motion and at rest whenever it is “reasonable and appropriate” to do so. I’ll bet that if you do a proper risk analysis, you’ll find very few scenarios where it’s not. Even if you think you’ve found one, and then you’re breached, you have to convince the OCR, who think encryption is both necessary and easy, that you’re correct. Is that an argument you want to be making in the face of hefty fines? Not me… and that’s why I have convinced myself that encryption is required by HIPAA. -

Someone might make it. It's a stretch, but it's a real concern. Are we enabling risky behaviour? Why?

That's news to me and I'm sure would be big news to most of the American public. Why is encryption considered an exception to security and privacy norms?

Of course it would. Encryption doesn't stop access, it just slows it down. In the case of assumed 10K maximum passwords, it slows it down by only a few seconds.

@BRRABill said:

If he can demonstrate that there was no exposure then there is no breach. Problem is... that cannot ever be demonstrated. So that's just misdirection and moot. Has nothing to do with the situation. Encryption does not prevent exposure so no need to discuss theoretical cases that can't happen.

You'll also see it mentioned int he article I attached.
Because they consider 256-bit encryption (was told only 256 bit qualifies as the "golden ticket", not 128 bit) uncrackable, ever.
You prove
a) you require strong complex passwords and
b) you required this password to unlock the encryption and
c) the encryption was enabledAnd that's all she wrote. Otherwise you are going on the HHS wall of shame!

@BRRABill said:

No way to ensure that they are not handing out the encryption passwords either. What's the point in that statement?
