Health Software and Health IT Systems Safety, Effectiveness and Security — Part 5-1: Security — Activities in the Product Life Cycle
The IEC standard defining the secure development life cycle for health software (Edition 1.0, December 2021). It layers cybersecurity activities onto the IEC 62304 software life cycle — security requirements, secure architecture and implementation, security verification, and post-market vulnerability handling — establishing a common framework for secure health-software processes rather than prescribing technical solutions.
What this does not cover
stated in the document's own scope- Covers health software and its connectivity to its intended environment of use; it is a process standard and does not prescribe specific technical security controls.
- Defines the security life cycle; the safety-focused software life cycle itself remains IEC 62304, and product-level requirements for marketed health software are IEC 82304-1.
- Addresses the manufacturer's development and maintenance activities; healthcare-organisation security management is covered elsewhere in the 81001 series.
Always verify against the current published text before relying on it for a submission or inspection.
Overview
IEC 81001-5-1 is the secure development life-cycle standard for health software — the cybersecurity process twin of IEC 62304. Published in December 2021 as Part 5-1 of the 81001 series on health software and health IT systems safety, effectiveness and security, it defines the activities and tasks a manufacturer performs so that security is engineered into health software across its life: security requirements and threat analysis, secure architecture and design, secure implementation and configuration management, security verification and validation testing, and post-market handling of vulnerabilities and security incidents. It is deliberately process-oriented — it establishes a common framework of life-cycle security activities rather than prescribing particular technical protections, and its structure parallels IEC 62304 so the two can run as one integrated life cycle.
Scope & applicability
Manufacturers of health software, covering the software and its connectivity to its intended environment of use. Process-oriented: it defines life-cycle security activities, structured to parallel IEC 62304, and supports conformance to IEC 62443-4-1.
Legal basis & how it acquires force
An international consensus standard developed jointly through IEC/ISO committees for health software, published as IEC 81001-5-1:2021 (Edition 1.0, December 2021). It is voluntary until invoked: the European harmonised version EN IEC 81001-5-1:2022 supports conformity with EU device legislation, and regulators reference the standard as the state of the art for secure health-software development. It also defines life-cycle requirements supporting conformance to IEC 62443-4-1, the industrial secure-development standard.
Document structure
| Part | Covers |
|---|---|
| General requirements | The quality-management context and the software life-cycle framing for security activities |
| Security in the software development process | Security requirements, secure architecture and design, secure implementation, and security testing through the development phases |
| Software maintenance and post-market activities | Vulnerability monitoring, assessment, and remediation for software in the field |
| Security risk management | Threat-driven risk analysis coordinated with the ISO 14971 risk-management framework |
| Configuration management and problem resolution | Controlled builds, third-party component management, and handling of security problems |
Key requirements
- Security activities integrated across the software development life cycle, from requirements to release
- Security risk management coordinated with the ISO 14971 risk-management framework
- Secure design, secure implementation, and security verification and validation testing
- Post-market management of vulnerabilities, including intake, assessment, and remediation
- Software configuration management and documentation supporting the security case
Implementation tips
- Map each 81001-5-1 security activity onto the corresponding 62304 phase in one combined SOP — running two parallel lifecycles is how the security work gets orphaned
- Regulators reference it as the state-of-the-art secure-development benchmark for device software; using it makes premarket cybersecurity documentation largely fall out of the process records
Revision notes
Published December 2021 (Edition 1.0); the European harmonised version is EN IEC 81001-5-1:2022. It is the security-process twin of IEC 62304, which remains the safety life-cycle standard.

International alignment
The standard is built on IEC 62304: it adds security activities phase by phase to the same life-cycle skeleton, so a manufacturer conformant to 62304 extends its process rather than starting a second one. Its risk activities interlock with ISO 14971, its product-level context is IEC 82304-1 for health software products, and it supports conformance to IEC 62443-4-1. FDA's premarket cybersecurity guidance and EU device cybersecurity expectations both describe outcomes this standard's process is designed to produce.
IEC 81001-5-1:2021: frequently asked questions
Quick answers to common questions about IEC 81001-5-1:2021.
What is IEC 81001-5-1?
The international standard defining a secure development life cycle for health software — the security activities a manufacturer builds into requirements, design, implementation, testing, release, and post-market maintenance. It was published in December 2021 and parallels the structure of IEC 62304.
How does IEC 81001-5-1 relate to IEC 62304?
IEC 62304 defines the software life-cycle processes for medical-device software with safety in view; 81001-5-1 layers cybersecurity activities onto that same life cycle. They are designed to be implemented together as one process, not run in parallel.
Is IEC 81001-5-1 mandatory?
No standard is mandatory of itself. It binds through invocation: the harmonised EN IEC 81001-5-1:2022 supports EU conformity assessment, and regulators treat the standard as the state of the art for secure health-software development, so conformance is the practical route to meeting cybersecurity expectations.
Does IEC 81001-5-1 cover post-market vulnerability handling?
Yes. The life cycle it defines extends past release: monitoring for vulnerabilities in the software and its third-party components, assessing exploitability and impact, and remediating through the maintenance process are in scope.
