Scalpel, Banana & Reciprocating Saw: Healthcare Data Security

There are a scalpel, a banana, and a reciprocating saw laid out on a cold steel desk in front of you.

Which do you pick out?

Well, in case you are a trained scientific professional about to perform the surgical procedure you’d be accomplishing for the scalpel (no longer to say having multiple questions). After many years of schooling, a clinical expert is aware that that’s the proper device for the job in terms of healthcare. They are superb at what they’re suitable at. However, about protecting the healthcare IT systems that assist help affected persons to care, they won’t be the appropriate candidate for the venture to hand. Attackers were focused on healthcare vendors an increasing number of as the cost of the health statistics has confirmed to be higher than the average credential set being discovered. Electronic fitness information, or EHRs, were established to have a higher value based totally on research. They incorporate a veritable treasure trove of statistics that not only have the call, address, employment, credit score facts, and so forth. They also contain all your clinical records.

That precise genie can’t be crammed lower back into the bottle. While you may take steps to mitigate the fallout from having your credit score playing cards exposed, there isn’t a lot you can do if your clinical data is uncovered. In point of truth, as of Dec. 27, 2018, the Department of Health and Human Services’ Office for Civil Rights (OCR) has acquired notifications of 351 data breaches of 500 or extra healthcare information. Those breaches have resulted in the exposure of 13,020,821 healthcare statistics.

This sincerely begs the query: how can these facts be better covered? Several steps may be taken to better shield EHRs standards. The first and predominant is encrypting the information. This is not an exercise. This is pervasive because it must be in 2019. While some corporations leverage encryption to shield their systems, there’s an identical measure of organizations that don’t shield the facts they’re responsible for. Another step that can be taken is to paint closer to de-identifying statistics so that within the event there may be an information breach, the aforementioned statistics can’t be mapped again to an individual.

Then there may be the want to have a strong eye toward 0 agree with from a networking angle. Network sector segmentation has constantly been an awesome exercise to ensure that the handiest systems and individuals who need to get entry can get the right of entry to systems and records. That being said, I have worked in environments inside the beyond in which there has been no such segmentation, and all of us connected to the network may want to view sources for which they’d no access requirement probably.

The venerable static password is one of the gotchas in any IT environment – and healthcare isn’t impervious to this. The value of in my view identifiable data (PII) rises whilst there are healthcare facts related to it. The attackers understand this, and they may thankfully leverage way together with phishing to advantage access to sensitive protected fitness records. Multi-element authentication (MFA) is a superb manner to help fight this hassle. If an attacker can gain get right of entry to passwords, they may now not offer an awesome go back if

MFA has been deployed. This is specifically actual if the MFA is utilizing Universal 2d Factor to confound the attacker similarly. U2F is an open authentication trendy that strengthens and simplifies two-issue authentication with the aid of making use of USB or near-subject conversation (NFC) devices together with YubiKeys. Attackers will not be going away every time quickly. Case in point, years ago, I changed into working for a defense contractor, and we would find our patron was constantly being attacked from all elements of the globe. One time out of frustration,n I requested any reasone why there might ever be legitimate site visitors from nations X, Y, and Z.
