In today’s landscape of increasingly connected devices, the fusion of healthcare and technology offers transformative opportunities in patient care. However, this digital evolution also opens a Pandora’s box of cybersecurity vulnerabilities, particularly in medical devices. Recognising this pressing issue, the US Food and Drug Administration (FDA) recently issued new regulations aimed at mitigating these risks. This action elevates cybersecurity to a central position in the manufacturing and management of medical devices.
Let’s take a comprehensive look back at our 17 August webinar, where we explored the FDA’s new regulations on medical device cybersecurity.
The Changing Landscape: Why Cybersecurity Matters
First things first: why is this a hot topic at the moment? As the Internet of Medical Things (IoMT) expands, the conversation around these FDA guidelines becomes more critical. We’re moving beyond the point where cybersecurity can be dismissed as just an IT issue. It’s now fundamentally a patient safety issue. Imagine a scenario where a medical device is compromised; the consequences could range from erroneous readings to altered functionality, or even life-threatening situations.
Legislative Updates: What Changed in the FDA Regulations
So what’s changed? Congress threw a curveball in December 2022 by updating the Federal Food, Drug, and Cosmetic Act (FD&C Act) through an omnibus bill. This introduced Section 524B, which allows the FDA to halt market clearance based on identified cybersecurity vulnerabilities. Manufacturers now have until March 2023 to comply. It’s worth noting that the FDA has begun issuing a Refuse to Accept (RTA) for premarket clearance applications that don’t comply with these new guidelines – effective 1 October. Note, however, that these changes are not retroactive; if your application was submitted before March 2023, you’re in the clear.
A Deep Dive into the FDA’s New Regulatory Stipulations
As we move from the ‘why’ to the ‘what’, let’s delve into the specifics of the FDA’s new regulations. These guidelines take a comprehensive view of the medical device lifecycle, from design through post-market surveillance. Here’s a snapshot of what manufacturers need to focus on:
Pre-Market: Planning for Security from Day One
Here’s what manufacturers need to consider before launch, according to the FDA:
Risk Management Plans
Manufacturers are now required to have a dedicated risk management plan that details the cybersecurity threats their devices might face, along with proposed mitigation strategies.
Configuration Management Plans
In line with the FDA’s new pre-market guidance, manufacturers must also include a configuration management plan. This outlines not only the device settings but also how they can be securely modified.
A Focus on Data Quality
High-quality data is critical to this process, especially if elements of your training or verification data come from publicly available databases. These databases must have well-maintained documentation to be considered reliable.
Post-Market: Ongoing Vigilance is Key
The FDA now expects companies to have a post-market cybersecurity plan in place. This isn’t just about responding to issues as they arise, but taking a proactive approach to identifying vulnerabilities before they can be exploited.
Data Reviews and Management Reviews
In the post-market phase, it is critical to have a broad scope of external reviews. These should include not only post-market surveillance data, but also any root causes that may have been previously overlooked. All these types of data should be integrated into your regular management review programmes. If significant risks emerge from these reviews, they need to be addressed in management discussions.
Cybersecurity Bill of Materials
Another new post-market expectation is the creation of a cybersecurity bill of materials, which lists all components that are critical to the cybersecurity aspects of the device.
Collaboration is Key: Information Sharing and Analysis Organizations
The new FDA regulations also encourage industry-wide collaboration through Information Sharing and Analysis Organisations. The cybersecurity landscape is constantly evolving, and staying ahead of threats requires collective intelligence. Information Sharing and Analysis Organizations are platforms for companies within the industry to share data about the cybersecurity threats and vulnerabilities they face. These collaborative efforts have gained particular traction in regions such as New Zealand, and are a powerful way to stay ahead of cyber threats.
Additional Layers of Cybersecurity: Points to Consider
To develop robust cybersecurity measures for your medical devices, it’s important to also keep the following considerations in mind:
Quality Data: The Building Block
Whether you are developing, verifying, or maintaining a medical device, data quality matters. If your data comes from publicly available databases, ensure that the database has well-maintained documentation, as this lends credibility and reliability to your own processes.
When conducting external reviews, don’t just focus on the data post-market; include broader reviews that capture any missed root causes or unidentified risks. This should be an integral part of your management review, combined with post-market surveillance and ISO data.
Make Cybersecurity a Priority
One of the most practical ways to allocate resources to your cybersecurity programme is to appoint a cybersecurity lead. Even if the lead only devotes part of their time, having a designated person responsible for this aspect can make a significant difference. This person should be included in policy documents and actively involved in annual planning.
Management’s Role: Plan, Don’t React
For executives and management, resource planning for cybersecurity is not optional, it’s a responsibility. Metrics and key performance indicators (KPIs) need to be developed and reviewed. If these are not being met, there must be adequate justification. Allocating sufficient resources to cyber security is critical. If you identify risks in your external reviews, these should be considered in management reviews.

Closing Thoughts: Good Engineering Equals Good Security
The new FDA guidelines may seem daunting, but remember: good engineering inherently includes good cybersecurity. The real challenge is documentation and proactivity. The best engineers in the medical device industry are not only competent, they are also adept at documenting their competence. So document rigorously, plan your resources wisely, and approach cybersecurity as an ongoing process rather than a one-off task.
In summary, the new FDA medical device cybersecurity regulations are not just regulatory measures; they are comprehensive best practices that are closely aligned with overall engineering quality. Therefore, fully understanding and implementing them not only ensures compliance, but also improves product quality and safety.
By adopting these guidelines, we can collectively help make healthcare safer, more reliable and ultimately more effective for everyone.
