Your answers and progress persist in this browser. 1. 1\. Where is your AI/ML device today? Pick the phase closest to where the team is spending time this week. Concept & feasibility Idea, early prototypes, no clinical data yet Model development Training runs, data pipeline, internal validation Premarket submission prep Assembling 524B artifacts and PCCP Cleared & on market Monitoring performance and vulnerabilities Active issue / drift / incident Something is off in the field right now 12 structured tips Checklist mode ## The walk-through 01 Documentation ### Treat the model as a software component in your SBOM Copy link Every deployed model artifact (weights, tokenizer, preprocessing pipeline) is a software component. Version-pin the model checkpoint, record its training-data provenance, and include it in your [SBOM](/glossary/sbom) as a first-class entry. Reviewers increasingly expect this even before FDA formalizes model-BOM guidance. 02 Threat Modeling ### Model the adversarial-input threat surface Copy link Extend [STRIDE](/glossary/stride) with an ML-specific pass: evasion (adversarial examples), poisoning (training-time corruption), model inversion (privacy leakage), model extraction (IP theft), and membership inference. For clinical models, focus first on evasion and poisoning — they map most directly to patient-safety harm. 03 Regulatory ### Scope your PCCP to exclude cyber-relevant components Copy link A Predetermined Change Control Plan can cover model retraining, threshold tuning, and expanded data — but explicitly exclude changes to authentication, cryptography, transport, or SBOM composition. Retraining that pulls in new libraries or new data sources should trigger a return to the [524B](/glossary/524b) process, not proceed under the [PCCP](/glossary/pccp). 04 Technical ### Add model integrity checks at load time Copy link Cryptographically sign model artifacts and verify signatures before loading. This defends against on-device model tampering and gives you a clean audit trail for postmarket investigations. 05 Postmarket ### Instrument for drift and adversarial telemetry Copy link Traditional postmarket vulnerability monitoring assumes discrete software versions. For ML devices, add continuous monitoring for distribution shift, prediction confidence anomalies, and input patterns consistent with adversarial probing. Drift can be a safety event and a security signal at the same time. 06 Documentation ### Document training-data governance in the technical file Copy link Reviewers want to see: provenance of every training dataset, controls on data ingestion (poisoning defense), retention and deletion policy, PHI handling, and a documented split between training, validation, and test sets. Poor data governance is the fastest path to a cyber deficiency letter on an ML device. 07 Technical ### Include prompt-injection defenses for LLM-based devices Copy link If your device incorporates a large language model or generative component, treat prompt injection and jailbreaks as first-class threats. Layered defenses (input filtering, output validation, tool-call allowlists, and human-in-the-loop for high-risk actions) belong in the security architecture — not the marketing FAQ. 08 Process ### Plan for model-specific incident response Copy link A vulnerable model is not always patchable with a code fix. Your incident response plan should include: rapid rollback to a prior model version, ability to disable the ML feature and revert to non-ML behavior, and a communication pathway that distinguishes model behavior changes from software vulnerabilities. 09 Technical ### Adversarial Robustness Testing Copy link Test AI/ML models against evasion, poisoning, and model-extraction attacks before submission. FDA reviewers now expect adversarial ML threats named explicitly in the threat model, with test evidence — not just a narrative acknowledgment. 10 Documentation ### Publish Model Cards and Datasheets Copy link Every clinically material model should ship with a model card (intended use, performance, known failure modes) and a datasheet for its training data (provenance, licensing, demographic coverage). These are increasingly requested in Q-Subs alongside the [SPDF](/glossary/spdf). 11 Documentation ### Distinguish MLBOM from SBOM Copy link An SBOM covers software components; an MLBOM (ML Bill of Materials) covers model weights, training datasets, and inference dependencies. Provide both when your device has a substantive ML component — CycloneDX 1.5+ supports MLBOM natively. 12 Process ### Define Drift-Monitoring Thresholds Copy link Predefine the drift metrics (input distribution, output distribution, performance) and thresholds that trigger action. Small drift = retrain under PCCP; large drift or new data source = new submission. Document the decision tree in your postmarket plan. ### Common pitfalls - Treating the model as data instead of a software component — no version pinning, no SBOM entry, no signed release. - PCCP scoping that silently permits changes to cyber-relevant components (auth, crypto, transport, dependencies). - No adversarial testing in the pentest scope — most IT pentesters do not test evasion or poisoning by default. - Ignoring training-data supply-chain risks (public datasets, third-party labels, synthetic data pipelines). - Postmarket monitoring that watches software versions but not model drift, confidence collapse, or adversarial input patterns. ### Your next steps 1. 1 Add an ML-threat-modeling pass (evasion, poisoning, inversion, extraction, membership inference) to your existing STRIDE model. 2. 2 Extend your SBOM to include model artifacts, tokenizers, and preprocessing pipelines with version and hash. 3. 3 Draft PCCP scope language that explicitly excludes cyber-relevant components from autonomous change. 4. 4 Add cryptographic signing and integrity verification at model load time. 5. 5 Build a postmarket telemetry plan covering distribution drift, adversarial input signatures, and confidence anomalies. ## Frequently asked questions Quick answers to the questions teams most often ask about this topic. ### How is AI/ML medical device cybersecurity different from traditional device cybersecurity? It adds a new threat surface on top of the traditional one. Adversarial inputs, training-data poisoning, model theft, and silent model drift are unique to learning-enabled devices. The traditional controls (auth, crypto, SBOM, CVD) still apply - you layer ML-specific defenses on top, not instead. ### Does FDA regulate AI/ML medical devices under the cybersecurity rules? Yes. Section 524B applies to any 'cyber device' regardless of whether it uses ML. FDA's premarket cyber guidance and postmarket expectations cover ML-enabled devices, and Predetermined Change Control Plans (PCCPs) provide a mechanism for shipping model updates without a new submission, provided the changes are scoped and pre-authorized. ### Should model artifacts appear in the SBOM? Yes. Model weights, tokenizers, and preprocessing pipelines are software components - version-pin them, record hashes, and include them in the SBOM. Reviewers increasingly expect a model-level entry, and it makes postmarket vulnerability triage far cleaner when a training-time issue is discovered. ### What threats should an ML threat model cover beyond STRIDE? Evasion (adversarial examples), poisoning (training-time corruption), model inversion (privacy leakage from the model), model extraction (stealing the model by querying it), and membership inference. For clinical AI, prioritize evasion and poisoning - they map most directly to patient-safety harm. ### How should a PCCP handle cybersecurity? Scope the PCCP so it explicitly excludes changes to cyber-relevant components: authentication, cryptography, transport, or SBOM composition. Retraining alone should not change those. If a planned update crosses that line, it returns to the standard 524B process instead of proceeding under the PCCP. ### What is an MLBOM and do I need one? An MLBOM (Machine Learning Bill of Materials) documents training data provenance, model architecture, hyperparameters, evaluation metrics, and known limitations. It is not yet mandated, but reviewers increasingly ask for it, and CycloneDX 1.5+ supports ML-BOM natively as a superset of the standard SBOM. ### How do we detect and respond to model drift in the field? Define acceptance thresholds during premarket (sensitivity, specificity, calibration) and monitor them continuously in postmarket. When drift exceeds threshold, the response should follow the same change-control path as any other safety-relevant deviation: risk-assess, remediate, and disclose per your CVD/postmarket plans.
