Cybersecurity Moves to the Forefront of Medical Device Design
The medical device industry is undergoing a significant shift in how it approaches cybersecurity. Once an afterthought, security is now a critical design consideration that must be woven into the entire product lifecycle. As May Lee, a medical device consultant at CS Life Sciences, explains, “Traditionally with the FDA’s cyber security requirements, it’s quite burdensome. The level of detail and the level of documentation that needs to be generated is really hefty. I think one of the important things that I’ve seen in the guidance is being able to incorporate a lot of more total product life cycle requirements and being able to weave it into your design control requirements.”
This heightened focus on security is driven by several factors, including:
- Increasing regulatory demands from the FDA, EU, and other global authorities
- The growing threat of cyber attacks targeting sensitive medical data and device functionality
- The need to future-proof devices against emerging threats like quantum computing
For medical device manufacturers, the message is clear: cybersecurity can no longer be an afterthought. It must be a core part of the design process from the very beginning.
Navigating the Regulatory Landscape
The regulatory environment surrounding medical device cybersecurity is complex and evolving. While the FDA has taken a more prescriptive approach, the EU’s Medical Device Regulation (MDR) and other global standards tend to be more generic, requiring manufacturers to interpret how to apply them.
As Trevor Slattery, the Chief Technology Officer and Director of MedTech Cybersecurity at Blue Goat Cyber, explains, “The FDA guidance is very mature from what we can see for a lot of different countries’ regulations. EU MDR and EU cybersecurity regulations try to lean on certain other standards like IEC62304 and 81001-5-1 as some of the main points of conversation for talking about how we’re designing medical software safely and securely. While the FDA of course utilizes those same standards, they have a little bit more of a prescriptive approach than the MDR, which is a bit more of a clear and easy forward path for a medical device manufacturer.”
Navigating these different regulatory frameworks is a critical challenge for medical device companies. As Christian Espinosa, the CEO and founder of Blue Goat Cyber, advises, “Begin with the end in mind. Figure out which markets you want to go to ahead of time, and then you can plan your strategy and work backwards from there. And you can also look at how I’m going to get reimbursed for this thing and how I’m actually going to make money because a lot of people don’t think about that and they come up with a cool product but there’s no one no adoption of the product because there’s no reimbursement category for it.”
Preparing for the Quantum Computing Threat
One of the most significant emerging cybersecurity challenges for medical devices is the threat of quantum computing. As May Lee explains, “Health data is very valuable and I think recently we’ve seen quite a lot of incidents where it’s obtained the data now to decrypt at a later time once quantum computing comes in. And I think one of the things is you know with software firmware, network connectivity with medical device, hospital networks, your electronic health records, all that. Now there’s like kind of an interconnectivity where if you for instance have a pacemaker, that pacemaker data connects to the hospital system, then the hospital system connects to a multitude of different patients. So it’s quite scary in that not to fear monger or anything but you know health data currently I think it’s like one of the biggest you know ticketed items and I think also coming from information security Europe the conference, there was a lot of talk about how you know it is you know not that distance of a future now and people are you know gathering and mining these data just to decrypt later.”
The challenge with quantum computing is that it has the potential to break many of the encryption methods currently used to protect sensitive medical data. As Trevor Slattery explains, “What was once secure is no longer considered secure. We can look at things like MD5, triple DES, which once upon a time were acceptable, but now they’re known to be vulnerable to all sorts of different cyber attacks. Where we find a little bit of challenge there is that post-quantum encryption is often going to be intensive from a resource perspective on a device or on a system compared to traditional encryption methodologies.”
This means that medical device manufacturers need to start thinking about how to future-proof their devices against the quantum computing threat. As May Lee notes, “I think in terms of just, you know, being aware that this is coming is quite important because you build it into your design controls and your risk management, right? So, it’s the manufacturer’s responsibility to ensure you do everything you can. It’s your burden to ensure safety and performance. One of the considerations is this, you know, looming idea of post-quantum computing.”
While there may not be a perfect solution to the quantum computing challenge, a risk-based approach that balances security with practicality is essential. As Trevor Slattery advises, “If there’s nothing that’s going to be sensitive, if it’s breached, what is really the impact? I mean, the the kind of the elephant in the room is pretty much all of our health data has already been stolen. So, does this even really matter?”
Addressing Supply Chain and Third-Party Risks
Another critical area of focus for medical device cybersecurity is the supply chain and the integration of third-party components. As May Lee explains, “One of the other things that we didn’t quite touch on which is equally as important is, you know, your supply chain, right? Like what type of software components are you using? Soup items, off-the-shelf software components, what are you using and you know how much visibility you have on the developers, the tech, what are you actually integrating in a device that’s under your responsibility so I think third-party risk management is going to become more important not that it’s ever less important but really like something to think about and highlight right?”
This issue is not unique to medical devices. As Christian Espinosa shares, “I used to do a lot of testing with aircraft, commercial aircraft, and this is one of the concerns we did because a commercial aircraft is an integrated system with a lot of different components and we had to look at every single piece of hardware that went into a component on an aircraft and test those from a cyber security perspective because you know one little component if it was contaminated could be leaking information to an adversary. Uh could be used in a negative way later on. I think medical devices are getting very similar to that because the FAA mandated specific third-party component risk assessment procedures. And I think with medical devices, we’re going that direction, not just from a software perspective, but also from a hardware perspective as well.”
Addressing these supply chain risks requires a comprehensive approach that goes beyond just the software components. Manufacturers must have a clear understanding of the entire ecosystem of hardware and firmware that makes up their device, and they must rigorously assess the security of each element.
Engaging Cybersecurity Experts Early and Often
Given the complexity of the regulatory landscape, the emerging threats like quantum computing, and the need to manage supply chain risks, medical device manufacturers would be well-advised to engage cybersecurity experts as early as possible in the development process.
As May Lee advises, “I always say as early as possible, right? Even honestly, even if it’s just an idea, reach out. We can discuss with you the types of things you need to think about, you know, at the first initial even feasibility stage, right? We can help you define your business strategy by explaining to you, you know, maybe go to this region first because then you can leverage, you know, information from this region for another region. Um, so we can have those conversations with you. It’s always helpful to have that kind of mindset and start from the very beginning.”
Trevor Slattery echoes this sentiment, noting that the ideal time to engage cybersecurity experts is “right when you’re starting to design that software and before you get your hands on the keyboard and start writing any code we want to talk about what standards are you writing the code to how are you ensuring you aren’t introducing any vulnerabilities through your coding practices through your development practices through your environment.”
By bringing in cybersecurity expertise early and often, medical device manufacturers can ensure that security is baked into the design from the ground up, rather than trying to bolt it on at the last minute. This not only helps to streamline the regulatory approval process, but it also reduces the risk of costly redesigns and delays down the line.
Balancing Compliance, Innovation, and Pragmatism
Ultimately, the key to navigating the evolving medical device cybersecurity landscape is to strike a balance between compliance, innovation, and pragmatism. As May Lee notes, “We always look at what is necessary to meet the regulations to be compliant ensuring safety and performance of the device while not you know burdening ourselves into like you said encrypting everything over compliance you know overworking a device because ultimately we want to bring these solutions to the market as soon as possible.”
Trevor Slattery echoes this sentiment, emphasizing that the regulators “aren’t trying to stifle innovation. They aren’t trying to prevent these from going out. So if you’re able to explain and justify your level of risk, they’re always open to listening. Of course, there’s a push for encryption on data. What that means and how far that goes is going to be flexible when you’re actually talking to the FDA, when you’re talking to the MDR. If you can present your case and say, ‘This data is not sensitive. It doesn’t need to be encrypted.’ They’re going to be understanding of that.”
By taking a risk-based approach, focusing on the most critical security requirements, and engaging with regulators in a collaborative manner, medical device manufacturers can navigate the complex cybersecurity landscape while still bringing innovative, life-saving products to market. As Christian Espinosa advises, “Begin with the end in mind. Figure out which markets you want to go to ahead of time and then you can plan your strategy and work backwards from there.”
With the right strategy, the right partnerships, and a commitment to security-by-design, medical device manufacturers can stay ahead of the curve and ensure that their products are both innovative and secure. By embracing this holistic approach to cybersecurity, the industry can continue to drive progress and improve patient outcomes, even in the face of evolving threats and regulatory demands.
