Connected medical devices, including wearables, implantable devices, and cloud-connected diagnostic systems are increasingly dependent on software and connectivity to support patient care. This proliferation of connected healthcare systems, however, introduces significant cybersecurity risks to the clinical management of patients as well as to healthcare systems and processes.
Recognizing these challenges the U.S. Food and Drug Administration (FDA) has recently strengthened their expectations regarding cybersecurity measures for medical devices throughout their entire life cycle. To support the industry in understanding these evolving requirements and thereby in developing innovative products in due time and without experiencing unintended delays during the review process by the regulatory bodies, we have elaborated an explanations paper.
Why Cybersecurity Has Become a Regulatory Priority
Healthcare is a highly targeted area by cybercriminals as healthcare organizations are rapidly deploying new technologies to support patient care. As the number of connected medical devices increases so does the risk of these devices being compromised by malicious activity. A single compromised medical device can disrupt patient care, compromise sensitive patient information or even put patients lives at risk.
There is growing recognition around the world that cybersecurity of medical devices is not just an information technology issue but also has direct bearing on the safety and effectiveness of the medical device. Consequently, the way in which medical devices are tested for safety and performance has to be broadened to include a cybersecurity component that covers the entire lifecycle of the device.
The FDA’s framework for ensuring the security of medical devices reflects this broader view of medical devices and their cybersecurity. It is no longer sufficient for a manufacturer to address security issues as a separate checklist item in preparation for submission of a product for FDA review. Rather, the manufacturer must demonstrate that all aspects of a device’s development — design, risk management, testing, etc. — as well as its maintenance and post-marketing activities have security integrated into them as well.
Understanding the FDA’s Risk-Based Approach
The FDA’s approach of cybersecurity in medical devices is a risk-based approach and characterizes medical devices in different cybersecurity profiles based on several factors including intended use, design, and functionality of the device (software/hardware), levels of connection (wired or wireless), and impact to patients’ in the event of compromise.
Risk is a consideration in determining the applicability of various safety and performance requirements for medical devices, including the need for cybersecurity. However, cybersecurity for medical devices cannot be analyzed in the same manner as physical hazards. Rather, the FDA focuses on the identification of potential security vulnerabilities, the likelihood of those vulnerabilities being exploited, and the impact that such exploitation could have on patient health and safety and on the device’s performance.
To manage and to reduce cybersecurity-related risks, use of industry standards and international frameworks for cybersecurity such as threat modeling, secure software development processes, vulnerability management and monitoring and analysing logs, and for ensuring the security of medical devices during their entire lifecycle can help to ensure that adequate cybersecurity measures are integrated in a quality management system.
Secure Product Development Starts Early
Cybersecurity in medical technology has to be embedded in the design process from the very start of product planning and development. The industry has long ago recognized that secure software development practices have to be integrated from the very outset into the design processes.
Security in software development encompasses security requirements’ definition, software architecture review, secure coding standards for software developers, security controls’ validation and documentation of all actions during the software’s development phase. Measures to minimize software vulnerabilities have to be put into place as early as possible in order to avoid potential dangers for patients and health care providers after the software has been released onto the market.
The same applies to the verification of the dependencies in the supply chain, such as third-party software libraries, commercial operating systems, or even cloud services and components, that are part of the software bill of materials of a medical device.
Documentation Matters as Much as Technical Controls
Importantly, whilst strong cybersecurity practices are key to managing the cybersecurity risks of a medical device, such measures must also be fully documented in order to provide adequate evidence of the steps that have been taken to identify, assess, mitigate and test for cybersecurity risks.
While the technical work of identifying, evaluating, and mitigating security risks can be done by the technical teams within a manufacturer, demonstrating compliance with security regulations requires evidence of what was done. That evidence includes documentation of how security risks were identified and how cybersecurity controls were evaluated for effectiveness.
Many organizations rely on the latest FDA cybersecurity guidance to better understand what documentation should accompany submissions. Well-organized cybersecurity documentation typically includes risk assessments, threat models, security architecture descriptions, testing reports, vulnerability management plans, software inventories, and post-market maintenance strategies that collectively demonstrate a proactive cybersecurity program.
Preparing for Post-Market Cybersecurity Responsibilities
Regulatory expectations do not end once a medical device reaches the market. Cybersecurity is considered an ongoing responsibility because new vulnerabilities and attack techniques continue to emerge throughout a product’s lifecycle.
Manufacturers are expected to monitor cybersecurity issues affecting their products, assess newly discovered vulnerabilities, and determine whether updates or corrective actions are necessary. This proactive approach helps reduce the likelihood that emerging threats will compromise patient safety or disrupt clinical operations.
An effective post-market cybersecurity program includes vulnerability monitoring, coordinated vulnerability disclosure processes, security update planning, incident response procedures, and communication strategies for healthcare providers. Organizations that establish these capabilities before commercialization are generally better prepared to respond efficiently when new cybersecurity concerns arise.
Common Challenges Manufacturers Face
Meeting cybersecurity expectations can be difficult, particularly for organizations transitioning from traditional medical device development practices. Many companies struggle with balancing innovation, development timelines, documentation requirements, and evolving regulatory expectations.
Smaller manufacturers may face resource limitations, while larger organizations often need to coordinate cybersecurity activities across multiple departments, including engineering, quality assurance, regulatory affairs, software development, and information technology. Ensuring consistent communication among these teams is essential for building a comprehensive cybersecurity strategy.
Another challenge involves keeping pace with rapidly changing threats and regulatory developments. Cybersecurity evolves much faster than many traditional engineering disciplines, requiring organizations to continuously update internal processes, employee training, and technical capabilities. Companies that establish a culture of continuous improvement are better equipped to adapt as expectations continue to mature.
Building a Sustainable Cybersecurity Culture
Cybersecurity should not be viewed solely as a regulatory obligation. Organizations that embrace cybersecurity as part of their overall quality culture often achieve stronger products, more efficient development processes, and greater customer confidence.
Leadership plays an important role in creating this culture. When executives recognize cybersecurity as a business priority rather than simply a technical requirement, teams receive the resources and organizational support needed to implement effective security practices throughout development and maintenance.
Cross-functional collaboration is equally important. Engineering teams, cybersecurity specialists, regulatory professionals, quality personnel, clinical experts, and management all contribute unique perspectives that strengthen cybersecurity decision-making. Regular communication helps identify risks earlier and reduces costly redesign efforts later in development.
Conclusion
Cybersecurity has become an essential component of medical device safety, quality, and regulatory compliance. As connected technologies continue to transform healthcare, manufacturers must demonstrate that security has been thoughtfully integrated into every stage of product development and maintenance rather than treated as a final compliance exercise.
Understanding the FDA’s expectations is ultimately about protecting patients while building resilient products capable of adapting to an evolving threat landscape. Organizations that combine secure development practices, thorough documentation, ongoing risk management, and a commitment to continuous improvement will be better prepared for regulatory review and better positioned to deliver safe, reliable medical technologies for years to come.
