The Med Device Cyber Podcast · October 30, 2025 This episode of the Med Device Cyber Podcast unpacks the seemingly simple yet often misunderstood definition of a "cyber device" according to FDA guidance. Hosts Christian Espinosa and Trevor Slatterie clarify that a medical device is considered a cyber device if it contains software and has any potential for internet connectivity, moving beyond traditional notions of Wi-Fi or Ethernet. They delve into specific examples of interfaces that transform a device into a cyber device, such as USB ports, serial ports, Bluetooth Low Energy (BLE), magnetic coils (RFID/NFC), and even HDMI, elaborating on how these seemingly innocuous connections can introduce significant cybersecurity risks. The discussion highlights that even off-the-shelf components and third-party software fall under FDA scrutiny. The hosts emphasize the importance of explicitly defining product boundaries and rigorously testing for all potential vulnerabilities, rather than assuming a device is secure. They also explore strategic approaches to re-engineer devices to avoid cyber device classification, or to implement robust mitigations, providing crucial insights for product security teams, regulatory leads, and engineers navigating FDA compliance and secure product development.
Key Takeaways
- A medical device is classified as a cyber device by the FDA if it contains software and has any possibility of internet connectivity, regardless of the interface type.
- Interfaces like USB, serial ports, Bluetooth Low Energy, RFID, NFC, and HDMI can all establish internet connectivity, even if indirect, making a device a cyber device.
- Third-party software and off-the-shelf components within a medical device's scope necessitate the manufacturer's responsibility to prove their secure implementation to meet FDA scrutiny.
- Manufacturers must meticulously define product boundaries and verify that all present and potentially present functionalities, especially those from off-the-shelf components, are secure or safely disabled.
- It is possible to re-engineer a device to remove it from cyber device classification, but this often involves making trade-offs in functionality, such as enclosing USB ports with tamper-proof seals.
- Always verify a device's cyber device classification with experts or the FDA, rather than making assumptions, to ensure compliance and avoid future complications.
