Overview
IEC 81001-5-1:2021 (Health software and health IT systems - Part 5-1) defines life‑cycle requirements to increase the cybersecurity of health software and health IT systems. Intended to support conformance with IEC 62443-4-1, the standard prescribes a common framework of processes, activities and tasks across the health software life cycle. It emphasizes maintaining an appropriate balance among safety, effectiveness and security (as discussed in ISO 81001-1) and focuses on activities in development, release, maintenance and decommissioning. The document does not prescribe the exact contents of accompanying documentation.
Key topics and technical requirements
- Secure life‑cycle processes: Establishes required activities across planning, development, integration, testing, release and maintenance phases of health software.
- Quality management & responsibilities: Calls for defined quality systems, explicit assignment of security responsibilities, and continuous improvement.
- Security risk management: Defines processes to identify vulnerabilities, assess threats, estimate and control security risks and monitor controls.
- Software classification & supplier management: Addresses classification of software items (e.g., maintained vs supported), and management of third‑party components.
- Secure design and implementation: Covers architectural defence‑in‑depth, secure design best practices and secure coding standards.
- Verification & testing: Requires security‑focused verification, vulnerability testing, threat mitigation testing and guidance on penetration testing and tester independence.
- Release & integrity controls: Covers release documentation, file integrity, private key controls and criteria for resolving security findings before release.
- Maintenance & vulnerability handling: Establishes maintenance planning, timely security updates, verification of updates and processes for receiving and addressing vulnerability reports.
- Configuration and problem resolution: Includes software configuration management and structured problem/incident resolution processes.
- Threat modelling & guidance: Informative annexes provide methods (e.g., STRIDE, attack‑defense concepts), implementation guidance and rationale.
Applications - who uses this standard
- Medical device manufacturers and health IT developers implementing a secure software development lifecycle (SSDLC).
- Cybersecurity, quality and regulatory teams preparing evidence for conformity to IEC 62443 or national medical device regulations.
- Clinical engineers, integrators and procurement officers who manage third‑party components and lifecycle patching.
- Test labs and auditors assessing security testing, vulnerability management and release controls.
