IEC 81001-5-1: §5.1.3
Requirement text
The manufacturer shall establish and maintain secure coding standards consistent with current best practices related to the design and implementation of secure software systems. See Annex A.4.
What changed
IEC 81001-5-1:2021 is the first standalone cybersecurity standard purpose-built for health software and medical device software. Published in December 2021, it was adapted from IEC 62443-4-1 (industrial control systems security) to address the unique safety and regulatory context of medical devices — adding 64 health-specific requirements that account for patient safety, clinical workflows, and the manufacturer-HDO relationship.
The standard mirrors IEC 62304's lifecycle structure but adds security-specific activities at every phase — planning, development, testing, release, and maintenance. It requires security risk management to be integrated with ISO 14971 safety risk management, not treated as a separate IT concern. FDA formally recognized it as Consensus Standard #13-112 in December 2022 and references it as providing a framework for the Secure Product Development Framework (SPDF) required by Section 524B.
EU MDR harmonization was originally targeted for May 2024 but postponed to May 2028. Despite this delay, Notified Bodies and Competent Authorities universally recognize it as "state of the art" for health software cybersecurity under MDR GSPR Annex I, Section 17.2. Missing or inadequate cybersecurity documentation is already a top cause of Notified Body major non-conformities for SaMD. A December 2025 Interpretation Sheet (ISH1:2025) clarified software item classification into maintained, supported, and required software categories, affecting risk transfer and post-market obligations.
Atomic constraints
- •Secure coding standards must be documented.
- •Standards must be maintained (kept current with evolving best practices).
- •Standards must be consistent with current best practices for secure software systems.
- •Standards must be applicable to the specific programming languages and technologies used.
Common gaps
Secure coding standards generic or absent
moderateManufacturers reference generic coding standards (MISRA, CERT) without tailoring them to the specific technology stack, threat model, and security requirements of their medical device software.
