Security teams should inventory AI and machine learning services, scan code repositories and training data for exposed keys, tokens, and sensitive records, and prioritize misconfigurations that create data exposure or poisoning risk. They should also validate that remediation guidance is tied to the affected asset and alert context, so investigators can act quickly without losing operational detail.
Why This Matters for Security Teams
AI and machine learning assets are not just another workload class. Model training code, notebooks, data pipelines, embeddings, and inference services often sit beside secrets, customer records, and operational tokens. If those assets are exposed, attackers can steal credentials, poison models, or pivot into cloud control planes. Guidance from the OWASP Non-Human Identity Top 10 and NHIMG research on secret sprawl shows that exposure usually begins with weak inventory and poor secret hygiene, not a single dramatic breach.
The practical risk is that AI assets often look harmless until a notebook, storage bucket, or CI job leaks keys embedded in code or training data. NHIMG’s 2024 Non-Human Identity Security Report found that 59.8% of organisations see value in dynamic ephemeral credentials, which reflects a growing recognition that long-lived secrets are a liability in machine-driven environments. In practice, many security teams encounter exposed AI credentials only after an alert has already been triggered by external abuse.
How It Works in Practice
Effective handling starts with asset-level visibility. Security teams should inventory AI and machine learning services by environment, owner, data source, and connected identity, then map where secrets may appear in code, notebooks, model artifacts, and pipeline metadata. That includes source repositories, object storage, feature stores, experiment tracking systems, and container images. NIST guidance in NIST SP 800-53 Rev 5 Security and Privacy Controls supports this kind of controlled visibility through inventory, access control, monitoring, and incident response requirements.
From there, remediation should be tied to the affected asset and alert context. A leaked API key in a training notebook is not the same as a credential found in a model deployment manifest. Investigators need enough context to revoke the right secret, isolate the right pipeline, and determine whether data exfiltration or model poisoning occurred. NHIMG’s Ultimate Guide to NHIs — Static vs Dynamic Secrets is useful here because AI workloads are often better served by short-lived, workload-bound credentials than by static secrets that linger across experiments and deployments.
- Scan repositories, notebooks, and IaC for keys, tokens, certificates, and service account material.
- Check training corpora and logs for accidental inclusion of sensitive records or embedded credentials.
- Prefer ephemeral access for model jobs, data pulls, and tool execution.
- Revoke and rotate exposed secrets immediately, then confirm downstream services are not still using them.
- Preserve alert context so responders can identify the exact dataset, asset, and execution path involved.
NHIMG’s 2024 Non-Human Identity Security Report also shows that only 19.6% of security professionals are strongly confident in managing non-human workload identities, which matches what is seen in AI environments where identity ownership is fragmented. These controls tend to break down when model teams can spin up new pipelines and storage locations without central registration, because exposed secrets then outrun the organisation’s ability to trace them.
Common Variations and Edge Cases
Tighter secret scanning and access controls often increase developer friction and incident response workload, so organisations have to balance speed of experimentation against containment and traceability. That tradeoff becomes sharper in research-heavy environments where notebooks are frequently cloned, shared, and re-run across projects. Current guidance suggests treating these cases as high risk even when the data is internal, because internal training sets can still carry customer information, credentials, or privileged operational context.
There is no universal standard yet for how deeply to inspect model artifacts, embeddings, or synthetic data for sensitive content, but best practice is evolving toward broader content inspection and stronger lineage tracking. Where teams use managed AI platforms, the same baseline still applies: discover the asset, classify the data, identify attached identities, and make sure the response workflow can revoke access without waiting for a human approval chain. The CSA Cloud Controls Matrix is useful for aligning cloud governance, while NHIMG’s 230M AWS environment compromise shows how quickly cloud identity mistakes can scale. In practice, the hardest cases are multi-account AI platforms where one leaked token can reach data stores, model registries, and deployment tooling before responders even know which workload originated it.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
OWASP Non-Human Identity Top 10 and CSA MAESTRO address the attack and risk surface, while NIST CSF 2.0 and NIST AI RMF set the governance and control requirements practitioners need to meet.

|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-01 | AI assets often leak non-human secrets through code, notebooks, and pipelines. |
| NIST CSF 2.0 | ID.AM-1 | You must know where AI and ML assets live before you can protect them. |
| CSA MAESTRO | GOV-2 | AI systems need governance over identities, data, and execution context. |
| NIST AI RMF | GOVERN | The question centers on managing AI risk from exposed data and credentials. |
