DIN EN IEC 81001-5-1 addresses security activities across the lifecycle of health software and health IT systems. It covers development, maintenance and supporting processes rather than prescribing one technical product feature.
Relevant themes include security responsibilities, risk management, requirements, architecture, implementation, verification, vulnerability handling and updates. The exact applicable edition and relationship to medical-device regulation should be checked for the product and market in question.
What does the standard change in practice?
Security evidence must be created as part of development and maintenance, not assembled only before release. Threat modeling, traceable requirements, secure update processes and post-market vulnerability handling become planned lifecycle work.
Which lifecycle activities are covered?
| Area | Practical task | Example evidence |
|---|---|---|
| Security management | Define roles, processes, competence and planning throughout the product lifecycle. | Security plan, responsibility matrix and approved procedures. |
| Requirements and architecture | Derive threats, protection needs, trust boundaries and security requirements traceably. | Threat model, architecture decisions and traceability. |
| Implementation and verification | Apply secure-development rules and test requirements based on risk. | Review results, test cases, scans and penetration-test reports. |
| Vulnerability management | Assess, coordinate, remediate and communicate findings. | Handling process, assessment and advisory. |
| Updates and maintenance | Provide secure, authentic and traceable updates. | Update design, signature verification and support planning. |
Which products is the standard relevant to?
IEC 81001-5-1:2021 defines a common framework for developing and maintaining health software while accounting for the needs of this field. It supports alignment with the secure-development processes in IEC 62443-4-1, but does not replace product-specific risk assessment or review of applicable medical-device and market-access requirements. Product role, intended purpose and target market remain decisive.
What does a technical security test cover?
Testing can examine authentication, authorization, data flows, interfaces, cryptography, update mechanisms and cloud or mobile components. It supplies evidence for concrete requirements and finds implementation defects. A one-off test cannot by itself fulfil process requirements such as ownership, continuous monitoring and post-market response.
