TL;DR: RBI’s June 2026 model risk guidance requires banks and other supervised firms to govern every model that affects a business decision, with live inventory, independent validation, and continuous monitoring now central to compliance, according to AccuKnox. Shadow models, third-party model updates, and multi-turn prompt attacks turn model governance into a runtime security problem rather than a paperwork exercise.

By the numbers:
- When AWS credentials are exposed publicly, attackers attempt access within an average of 17 minutes and as quickly as 9 minutes in some cases.
Questions worth separating out
Q: What breaks when AI systems are deployed without a complete inventory?
A: Governance breaks first, then auditability.
Q: Why do third-party models still create regulatory risk?
A: Because accountability does not transfer with the vendor certificate.
Q: What do security teams get wrong about prompt filtering for AI agents?
A: They treat prompt filtering as if it were a complete control layer.
Practitioner guidance
- Map every production model to a live inventory Create a continuously updated register that includes in-house models, hosted models, notebooks, inference containers, datasets, and pipeline dependencies.
- Red-team third-party models on your own terms Test hosted models for prompt injection, jailbreaks, hallucination, toxic output, and unsafe code using your own business scenarios, not only vendor assurances.
- Enforce stateful prompt controls in production Move from single-prompt filtering to conversation-aware controls that score the full session, cap context growth, and block unsafe responses at the boundary.

- Discovery coverage across Bedrock, SageMaker, Vertex, Azure, Ollama, vLLM, and Triton in both cloud and on-prem estates
- Red-teaming findings for prompt injection, jailbreaks, hallucination, toxic output, and unsafe code with documented test evidence
- Stateful prompt firewall behavior across normalize, classify, contextualize, score, and enforce stages
- Runtime enforcement examples that block unsafe file access and response leakage at the operating system layer

Live inventory is the new compliance floor: RBI’s guidance effectively treats discoverability as a mandatory security control, not an administrative task. If an organisation cannot enumerate every model, notebook, inference container, and external dependency, it cannot credibly claim control over model risk. That shifts governance from periodic approval to continuous estate awareness. Practitioners should treat inventory drift as a compliance failure, not a housekeeping issue.
A question worth separating out:
Q: Who is accountable when an AI model fails a regulated decision review?
A: Accountability sits with the organisation operating the system, not with the benchmark or the evaluation tool. Teams need named owners for testing, monitoring, remediation, and sign-off, because regulators expect evidence of ongoing control. If the AI system influences a high-stakes decision, governance must show who approved the risk and who monitors it.
