Why do I need a Quality Management System (QMS)?
IMPORTANT: This topic was last updated July 2025. Although Medcrypt attempts to keep this up-to-date, you should always check the latest FDA guidances and consult with qualified regulatory professionals for your specific situation. This content provides general information about QMS cybersecurity considerations and is not intended as regulatory consulting advice for your specific device or situation.
Overview
A Quality Management System (QMS) is a structured system that documents processes, procedures, and responsibilities for continuously delivering high-quality products and services that meet regulatory and customer requirements. In the cybersecurity context, your QMS becomes the foundation for implementing and maintaining security throughout your device lifecycle.
For medical device cybersecurity specifically, your QMS should typically integrate security as a core design control under 21 CFR Part 820, based on current FDA guidance.
General QMS benefits
Regulatory compliance
Compliance with quality standards and regulations applicable to your company
Structured documentation for audits and inspections
Consistent processes across teams and locations
Clear accountability and responsibility chains
Operational excellence
Improved quality via continual improvement and streamlining of quality processes
Increased customer satisfaction: Provide good quality products and services to keep customers happy and reduce churn
Improved efficiency: Eliminating waste and streamlining processes increases efficiency and productivity
Reduced costs associated with rework, waste, customer complaints, and employee attrition
Better communication and collaboration across your company and between team members
Cybersecurity-specific QMS benefits
Security by Design integration
SPDF implementation: Your QMS provides the framework for integrating Secure Product Development Framework throughout your Total Product Lifecycle (TPLC)
Design controls: Enables systematic cybersecurity risk assessment and mitigation as required under FDA guidance
Traceability: Links security requirements to design inputs, verification, and validation activities
Vulnerability and incident management
Vulnerability tracking: Systematic processes for identifying, assessing, and addressing cybersecurity vulnerabilities
Incident response: Documented procedures for cybersecurity incident detection, containment, and recovery
Change control: Ensures security implications are evaluated for all device modifications
Supplier management: Cybersecurity requirements and assessments for third-party components
Documentation and evidence
FDA submission support: Organized cybersecurity documentation for premarket submissions
SBOM management: Systematic tracking of software components and vulnerabilities
Security testing records: Documentation of penetration testing, threat modeling, and security validation
Training records: Evidence of cybersecurity awareness and competency across teams
Medical device-specific considerations
Regulatory requirements
Your QMS should typically address FDA cybersecurity requirements including:
Section 524B compliance for cyber devices (where applicable)
Postmarket surveillance for cybersecurity vulnerabilities
CISA reporting preparedness for applicable critical infrastructure entities
Risk management integration combining ISO 14971 safety risk with cybersecurity risk considerations
Patient safety focus
Clinical risk assessment: Understanding how cybersecurity failures could impact patient care
Essential performance: Ensuring cybersecurity controls don't interfere with critical device functions
Usability considerations: Security controls that healthcare workers can realistically implement
Interoperability security: Managing cybersecurity across connected healthcare ecosystems
Lifecycle management
Legacy device management: Processes for maintaining security of older devices in the field
Update and patching: Systematic approach to security updates throughout device lifecycle
End-of-life planning: Secure decommissioning and data protection procedures
Supply chain security: Vendor cybersecurity assessments and ongoing monitoring
QMS Framework for Cybersecurity
Process integration
Your cybersecurity activities should integrate with existing QMS processes:
Design and development:
Cybersecurity requirements definition
Threat modeling and risk assessment
Security architecture and design
Security verification and validation
Manufacturing and distribution:
Secure manufacturing processes
Malware-free shipping procedures
Supply chain security controls
Configuration management
Post-market activities:
Vulnerability monitoring and assessment
Security update deployment
Incident response and reporting
Cybersecurity effectiveness monitoring
Documentation structure
Essential cybersecurity documents within your QMS:
Cybersecurity plan and procedures
Threat model and risk assessment
SBOM and vulnerability tracking
Security test plans and results
Incident response procedures
Training and competency records
Implementation recommendations
Start with risk-based approach
Assess your current cybersecurity maturity
Identify gaps between current state and FDA requirements
Prioritize improvements based on patient safety impact
Develop implementation roadmap with measurable milestones
Leverage existing standards
ISO 13485: Medical device quality management foundation
ISO 14971: Risk management processes
AAMI TIR 57: Security risk management guidance
AAMI SW96: Security assurance for medical device software
Build organizational capability
Cross-functional teams: Include cybersecurity expertise in quality processes
Training programs: Cybersecurity awareness for all personnel
Competency management: Defined cybersecurity roles and responsibilities
Continuous improvement: Regular assessment and enhancement of cybersecurity processes
Key Takeaways
Bottom line: Based on current regulatory trends, a QMS without integrated cybersecurity management may be incomplete for medical device manufacturers. Consider making cybersecurity a systematic part of how you develop, manufacture, and maintain medical devices throughout their lifecycle. Consult with regulatory experts to determine the best approach for your specific situation.
QMS provides cybersecurity foundation - Generally serves as the required framework for systematic cybersecurity management in regulated environments
Integration is typically essential - Cybersecurity should generally be woven throughout your QMS rather than bolted onto existing processes
Regulatory advantage - A well-structured QMS can significantly simplify FDA cybersecurity submissions and ongoing compliance
Patient safety imperative - Your QMS should help ensure cybersecurity enhances rather than compromises clinical care
Business resilience - Systematic cybersecurity management typically protects your business continuity and reputation
