Medical Device Cybersecurity Practices: Best Practices, Requirements & Standards
Medical devices are becoming increasingly connected through hospital networks, cloud platforms, mobile applications, wireless communication, and other digital technologies. While connectivity improves patient care and device functionality, it also creates cybersecurity risks that manufacturers must address throughout the product lifecycle.
Medical device cybersecurity practices help manufacturers protect devices, patient data, software, and connected systems from unauthorized access, vulnerabilities, cyberattacks, and operational disruption. Cybersecurity should be considered from the early design stage through development, regulatory submission, market launch, and postmarket monitoring.
For manufacturers planning regulatory approval in the United States, understanding FDA cybersecurity expectations is especially important.

What Is Medical Device Cybersecurity?
Medical device cybersecurity refers to the processes, technologies, and controls used to protect a medical device and its associated systems from cybersecurity threats.
A connected medical device may contain software, communicate with external systems, transmit patient information, connect to a network, or receive software updates. These features can introduce potential vulnerabilities.
An effective cybersecurity program should protect:
- Patient and clinical data
- Device software and firmware
- Network connections
- Cloud services and applications
- Communication interfaces
- User accounts and credentials
- Software components and third-party libraries
The primary objectives are to maintain the confidentiality, integrity, and availability of device information and functions.
Why Is Medical Device Cybersecurity Important?
A cybersecurity vulnerability can affect more than data privacy. In certain circumstances, unauthorized access or manipulation could affect the safety or performance of a medical device.
Strong cybersecurity practices can help manufacturers:
- Protect sensitive patient information
- Reduce cybersecurity vulnerabilities
- Support patient safety
- Meet regulatory expectations
- Improve device reliability
- Manage software and third-party components
- Respond to newly discovered vulnerabilities
- Support secure software updates throughout the device lifecycle
Cybersecurity is therefore an important part of medical device design, risk management, regulatory compliance, and postmarket support.
Medical Device Cybersecurity Practices
Manufacturers should integrate cybersecurity activities throughout the medical device lifecycle. Some of the key practices include:
1. Implement Security by Design
Cybersecurity should be considered during product design instead of being added after development. Manufacturers should identify cybersecurity requirements and incorporate appropriate security controls into the device architecture.
These controls may include authentication, authorization, encryption, secure communication, access restrictions, and mechanisms for secure software updates.
2. Conduct Threat Modeling
Threat modeling helps manufacturers identify potential threats, attack paths, system vulnerabilities, and affected assets.
A threat model should consider:
- Device interfaces
- Network connections
- User access
- External systems
- Software components
- Data flows
- Potential attack vectors
The results can then be used to define appropriate cybersecurity controls and risk mitigation measures.
3. Establish Cybersecurity Risk Management
Cybersecurity risks should be identified, assessed, controlled, and monitored throughout the product lifecycle.
Manufacturers should maintain documented cybersecurity risk management activities and establish a clear connection between identified threats, cybersecurity risks, controls, and verification activities.
Cybersecurity risk management should work alongside, but should not simply replace, medical device safety risk management.
4. Maintain a Software Bill of Materials
A Software Bill of Materials, or SBOM, identifies the software components included in a medical device.
An SBOM can help manufacturers understand their software supply chain and identify affected components when a new vulnerability is discovered. It is particularly important for devices that use open-source or third-party software.
5. Use Strong Access Controls and Encryption
Manufacturers should implement appropriate authentication and authorization controls to prevent unauthorized access.
Depending on the device and its intended environment, cybersecurity controls may include:
- User authentication
- Role-based access
- Least-privilege access
- Password controls
- Encryption of sensitive data
- Secure communication protocols
6. Perform Cybersecurity Testing
Cybersecurity testing helps verify that implemented controls work as intended.
Testing may include vulnerability assessments, static and dynamic analysis, software security testing, penetration testing, and other appropriate security verification activities.
Identified vulnerabilities should be evaluated and addressed based on their potential impact.
7. Establish a Secure Software Update Process
Manufacturers should have processes for securely delivering software updates and security patches.
The update process should consider authentication, authorization, integrity verification, rollback capabilities, update validation, and communication with users.
8. Monitor Cybersecurity Risks After Market Launch
Cybersecurity does not end when a device receives regulatory clearance or approval. Manufacturers should continue monitoring vulnerabilities and emerging threats after commercialization.
Postmarket activities may include vulnerability monitoring, incident response, security updates, coordinated vulnerability disclosure, and evaluation of newly identified risks.
FDA Medical Device Cybersecurity Requirements
The U.S. FDA has established specific cybersecurity expectations for certain medical devices. Section 524B of the Federal Food, Drug, and Cosmetic Act addresses cybersecurity requirements for devices that meet the applicable definition of a “cyber device.”
FDA’s current cybersecurity guidance, issued in February 2026, provides recommendations concerning cybersecurity considerations in device design, labeling, and information manufacturers should include in premarket submissions.
Manufacturers should therefore consider cybersecurity documentation when preparing applicable 510(k), De Novo, or PMA submissions.
Cybersecurity activities may include documenting:
- Cybersecurity risk management
- Threat modeling
- Security architecture
- Security controls
- Software components
- Vulnerability assessments
- Security testing
- Software update processes
- Postmarket cybersecurity processes
Manufacturers should review the current FDA guidance and applicable requirements based on the specific characteristics and risk profile of their device.

Medical Device Cybersecurity Standards
Several standards and frameworks can support cybersecurity activities for medical devices. Depending on the product and applicable regulatory requirements, manufacturers may consider:
| Standard or Framework | Relevance |
|---|---|
| ISO 14971 | Medical device risk management |
| IEC 62304 | Medical device software lifecycle processes |
| AAMI TIR57 | Principles for medical device security risk management |
| IEC 81001-5-1 | Health software and health IT security |
| NIST Cybersecurity Framework | Cybersecurity risk management |
These standards and frameworks may help manufacturers establish structured cybersecurity processes, but their applicability depends on the device, market, and regulatory pathway.
Medical Device Cybersecurity Checklist
Before commercialization, manufacturers should consider whether they have:
- Identified cybersecurity requirements
- Conducted threat modeling
- Performed cybersecurity risk assessment
- Defined security controls
- Established a secure architecture
- Created and maintained an SBOM
- Conducted cybersecurity testing
- Addressed identified vulnerabilities
- Established secure software update processes
- Prepared appropriate cybersecurity documentation
- Defined postmarket vulnerability monitoring processes
