Overview

EN ISO/IEEE 11073-40101:2022 defines a foundational, repeatable process for cybersecurity vulnerability assessment specifically for Personal Health Devices (PHDs) and Point‑of‑Care Devices (PoCDs). Published and adopted by CEN in 2022, this standard frames cybersecurity as both a capability and a process (including risk analysis of use cases) within secure plug‑and‑play device interoperability. It prescribes an iterative, systematic, scalable and auditable method to identify vulnerabilities and estimate residual risk until risk is reduced to an acceptable level.

Key Topics

• Scope and context: Addresses cybersecurity in the context of device interoperability and medical device communication (PHD/PoCD environments).
• Iterative assessment workflow: Defines steps including system context, system decomposition, pre‑mitigation scoring, mitigation design, and post‑mitigation scoring - repeated until acceptable risk is achieved.
• STRIDE threat classification: Uses Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, and Elevation of Privilege to categorize threats.
• Embedded CVSS (eCVSS): Integrates the Common Vulnerability Scoring System to quantify vulnerability severity for pre‑ and post‑mitigation scoring.
• Risk analysis of use cases: Emphasizes analyzing device use cases and operational context to prioritize vulnerabilities and mitigations.
• Auditability and scalability: Designed for traceable evidence of assessment decisions and suitable for devices ranging from simple PHDs to complex PoCD systems.

Applications

• Medical device manufacturers can use this standard to build cybersecurity into product development and maintainers can apply it during lifecycle updates.
• Healthcare IT and clinical engineers can apply the process to evaluate interoperability risks when integrating devices into hospital networks or home health ecosystems.
• Regulatory and compliance teams can use documented assessments (pre/post mitigation scores and iterations) as part of evidence for cybersecurity risk management and conformity.
• Security assessors and auditors use the STRIDE + eCVSS approach for consistent vulnerability classification and scoring across device types.

Who should use this standard

• Device manufacturers (PHD/PoCD vendors)
• Systems integrators and clinical engineers
• Cybersecurity assessors, QA and compliance teams in healthcare
• Regulatory bodies and procurement teams evaluating medical device security

Related Standards

• Part of the ISO/IEEE 11073 family for medical device interoperability; aligns with broader medical device cybersecurity and healthcare IT guidance. Use in conjunction with relevant regional regulatory guidance and risk‑management standards for medical devices.
