What Is Medical Device Cybersecurity? Essential FDA & Regulatory Guide
Medical devices are becoming more connected to software, cloud platforms, hospital networks, mobile applications, and the internet. While connectivity can improve patient care and device functionality, it can also create cybersecurity risks. A vulnerability in a connected device may affect patient safety, device performance, sensitive information, or healthcare operations.
Medical device cybersecurity is therefore an important part of medical device design, regulatory compliance, risk management, and postmarket monitoring.
For manufacturers developing connected or software-enabled medical devices for the US market, cybersecurity should be addressed throughout the product lifecycle, not treated as an activity completed just before an FDA submission.

What Is Medical Device Cybersecurity?
Medical device cybersecurity is the process of protecting a medical device, its software, data, and connected systems against unauthorized access, manipulation, disruption, and other cybersecurity threats.
Cybersecurity considerations can apply to devices such as:
- Connected patient monitoring systems
- Software as a Medical Device (SaMD)
- Wearable medical devices
- Infusion pumps and other connected therapeutic devices
- Imaging and diagnostic systems
- Remote monitoring devices
- Devices connected to hospital networks or cloud platforms
An effective medical device cybersecurity risk management approach aims to protect three key areas:
- Confidentiality: Protect sensitive health and device information.
- Integrity: Prevent unauthorized modification of software, data, or device functions.
- Availability: Help ensure the device remains functional and accessible when needed.

Why Is Cybersecurity Important in Medical Devices?
Cybersecurity is directly connected to medical device safety and effectiveness. A cyberattack or software vulnerability could potentially alter device functionality, interrupt healthcare services, expose sensitive information, or create risks for patients.
For manufacturers, cybersecurity weaknesses can also lead to regulatory concerns, additional testing, remediation costs, delayed submissions, and reputational damage.
This is why cybersecurity for medical devices should be incorporated into design controls, software development, risk management, quality processes, verification and validation, and postmarket activities.

Regulatory Expectations for Medical Device Cybersecurity
Regulators across the globe have released specific guidelines to help manufacturers build secure devices. Here’s a quick overview:
- FDA (USA)
The U.S. Food and Drug Administration (FDA) has issued multiple cybersecurity guidance documents:
- Premarket Guidance (2023 update): Requires manufacturers to include a Software Bill of Materials (SBOM), threat modeling, and cybersecurity risk assessments in their submissions.
- Postmarket Guidance: Emphasizes continuous monitoring, vulnerability disclosure, and remediation.
- EU MDR
Under EU MDR, cybersecurity is a core component of General Safety and Performance Requirements (GSPR). Manufacturers must consider cybersecurity from the design stage and document risk management strategies.
- Other Regions
Countries such as Canada, Australia, Japan, and India are also integrating cybersecurity into medical device regulations, often aligning with IMDRF (International Medical Device Regulators Forum) principles.
What Are the FDA Cybersecurity Requirements for Medical Devices?
The FDA has established specific expectations for medical device cybersecurity FDA requirements, particularly for devices with cybersecurity risk.
The FDA’s February 2026 final guidance, “Cybersecurity in Medical Devices: Quality Management System Considerations and Content of Premarket Submissions,” provides recommendations covering cybersecurity design, labeling, and information included in premarket submissions. It also addresses Section 524B of the Federal Food, Drug, and Cosmetic Act for “cyber devices.”
Under Section 524B, manufacturers submitting qualifying premarket applications for a cyber device must address cybersecurity requirements. These submissions can include 510(k), De Novo, PMA, PDP, and HDE submissions.
Key requirements include:
1. Cybersecurity Risk Management
Manufacturers should identify cybersecurity threats and vulnerabilities and evaluate their potential impact on device safety and effectiveness.
Threat modeling and security risk analysis can help identify attack surfaces and establish appropriate controls during product development.
2. Software Bill of Materials (SBOM)
A medical device SBOM provides an inventory of software components used in a device, including relevant third-party, commercial, open-source, and off-the-shelf components.
For cyber devices, an SBOM is required under Section 524B. The FDA’s current guidance also discusses machine-readable SBOM documentation and information related to software component maintenance and end-of-support dates.
3. Vulnerability Monitoring and Management
Manufacturers need processes for identifying, assessing, and addressing cybersecurity vulnerabilities throughout the device lifecycle.
This includes planning for vulnerability disclosure, monitoring, remediation, and appropriate software updates or patches.
4. Secure Design and Development
Cybersecurity should be considered during device design and software development. Security controls may include authentication, authorization, encryption, secure communications, access controls, logging, and protection against unauthorized changes.
What Cybersecurity Documentation May Be Needed for FDA Submissions
Manufacturers preparing an FDA submission for a device with cybersecurity risk should be prepared to document relevant cybersecurity activities and controls.
Depending on the device and submission, documentation may address:
- Cybersecurity risk assessment
- Threat modeling
- Security architecture
- Cybersecurity requirements
- Software Bill of Materials
- Vulnerability assessment
- Verification and validation activities
- Security testing
- Software update and patching processes
- Postmarket cybersecurity plans
- Coordinated vulnerability disclosure procedures
The FDA’s current guidance provides recommendations for cybersecurity information in premarket submissions, while Section 524B establishes specific statutory requirements for cyber devices.
Medical Device Cybersecurity Best Practices
Manufacturers can strengthen their medical device cybersecurity compliance by integrating security into the entire product lifecycle.
Build Security Into the Design
Use threat modeling and cybersecurity requirements from the early stages of product development rather than attempting to add security after development is complete.
Maintain an Updated SBOM
Keep the medical device SBOM current as software components change. This can support vulnerability identification and software component traceability.
Perform Security Testing
Testing can include vulnerability assessments, penetration testing, authentication testing, access control testing, and other security verification activities appropriate to the device.
Establish a Vulnerability Management Process
Manufacturers should have defined processes for receiving, assessing, prioritizing, and remediating cybersecurity vulnerabilities.
Integrate Cybersecurity With the QMS
Cybersecurity activities should work with the manufacturer’s quality management and design control processes. For manufacturers preparing for the US market, aligning cybersecurity documentation with the broader medical device QMS can help create a more organized regulatory submission and lifecycle management process.
Cybersecurity Is a Lifecycle Responsibility
Medical device cybersecurity does not end when a device receives FDA clearance or approval. Cybersecurity threats can change after commercialization, and new vulnerabilities may be discovered in device software or third-party components.
Manufacturers should therefore consider cybersecurity across design, development, testing, regulatory submission, production, deployment, maintenance, software updates, vulnerability management, and eventual device retirement.
For manufacturers developing a connected medical device, addressing cybersecurity early can help reduce regulatory risk and support safer product development.
