International Harmonization

Medical device cybersecurity requirements are converging globally around IMDRF's 2020 guidance, which major regulators including FDA helped write. The EU MDR, Health Canada, Japan's PMDA, and Australia's TGA all draw on the same principles, so a program built for FDA gets you most of the way in other markets. Documentation format is the main thing that changes.

2.6.1 IMDRF - The Global Perspective

The International Medical Device Regulators Forum (IMDRF) works to harmonize medical device regulation globally. Their cybersecurity guidance influences regulators worldwide.

"Principles and Practices for Medical Device Cybersecurity" (March 2020)

• Represents consensus among major regulatory authorities
• FDA participated in development
• Aligns with FDA expectations
• Used by other countries as basis for requirements

Key IMDRF Principles:

1. Total Product Lifecycle (TPLC) approach
2. Shared responsibility model
3. Risk-based implementation
4. Transparency in communication

2.6.2 European Requirements

MDR (Medical Device Regulation) - EU 2017/745

• Includes general cybersecurity requirements
• Requires demonstration of cybersecurity measures
• Post-market surveillance includes cybersecurity

MDCG 2019-16 - Cybersecurity Guidance

• European Commission guidance on MDR cybersecurity
• Similar principles to FDA but different documentation
• Emphasizes "state of the art" security

Key Differences from FDA:

• More prescriptive on some technical requirements
• Different documentation formats
• Notified Body review vs. FDA review
• GDPR privacy requirements overlay

2.6.3 Other Major Markets

Canada (Health Canada)

• Generally aligns with FDA approach
• Accepts FDA cybersecurity documentation
• Additional privacy requirements

Japan (PMDA)

• Increasing focus on cybersecurity
• References international standards
• Moving toward IMDRF alignment

Australia (TGA)

• Follows international standards
• Risk-based approach
• Increasing scrutiny of cybersecurity
