Frequently asked questions

What are the FDA cybersecurity requirements for SaMD?

Short answer: SaMD cybersecurity FDA requirements is a discrete deliverable inside the Secure Product Development Framework (SPDF). FDA expects it documented, traceable, and version-controlled inside your QMS. For the full context, work through the relevant section above and the linked services below — every answer here is grounded in current FDA guidance and the standards your reviewer is using.

Does SaMD require a Softare Bill of Materials (SBOM)?

Short answer: Yes — under Section 524B and the February 2026 final guidance, every cyber device requires the artifact in question. Skipping it is the fastest way to an RTA hold. For the full context, work through the relevant section above and the linked services below — every answer here is grounded in current FDA guidance and the standards your reviewer is using.

How does FDA Section 524B affect software-only medical devices?

Short answer: Treat it as a process, not a one-off document: own the requirement in design controls, map it to a current standard, generate evidence during V&V, and surface the residual risk in your postmarket plan. For the full context, work through the relevant section above and the linked services below — every answer here is grounded in current FDA guidance and the standards your reviewer is using.

Is penetration testing required for SaMD FDA clearance?

Short answer: It depends on the device classification, intended use, and connectivity profile — but the controlling references are FDA's February 2026 premarket guidance, AAMI SW96, and IEC 81001-5-1. The sections above walk through how each applies. For the full context, work through the relevant section above and the linked services below — every answer here is grounded in current FDA guidance and the standards your reviewer is using.

How do I document threat modeling for a software medical device?

Short answer: Treat it as a process, not a one-off document: own the requirement in design controls, map it to a current standard, generate evidence during V&V, and surface the residual risk in your postmarket plan. For the full context, work through the relevant section above and the linked services below — every answer here is grounded in current FDA guidance and the standards your reviewer is using.

What is the difference between premarket and postmarket SaMD cyber requirements?

Short answer: SaMD cybersecurity FDA requirements is a discrete deliverable inside the Secure Product Development Framework (SPDF). FDA expects it documented, traceable, and version-controlled inside your QMS. For the full context, work through the relevant section above and the linked services below — every answer here is grounded in current FDA guidance and the standards your reviewer is using.
