2. FDA's scope is broader than the law - Even if not a "cyber device," FDA expects cybersecurity for any software

3. Standards provide the implementation roadmap - FDA references numerous standards as acceptable approaches

4. International alignment is increasing - IMDRF and other efforts drive global harmonization

5. Documentation is critical - Proper documentation demonstrates compliance

6. It's not just about compliance - Good cybersecurity protects patients and business

7. The framework continues to evolve - Stay current with changes

8. Resources are available - Industry groups, standards, and tools can help

Remember: Understanding the regulatory framework is the foundation for building a compliant and effective medical device cybersecurity program. The regulations tell you what needs to be done, the standards tell you how to do it, and the guidance helps you understand FDA's expectations.
