AWS Bedrock permissions: what IAM teams need to govern now

TL;DR: Broad Bedrock permissions can bypass existing identity controls, expose sensitive prompts and data, and drive uncontrolled model usage, according to P0 Security. The governance problem is not AI experimentation itself but who can invoke, manage, and share models, and under what identity boundaries.

Questions worth separating out

Q: How should security teams govern Bedrock access for AI workloads?

A: Security teams should govern Bedrock access as privileged access, not routine application access.

Q: Why do broad model invocation rights create governance risk?

A: Broad invocation rights allow an identity to process sensitive prompts, expose internal data, and generate uncontrolled cost or output at scale.

Q: What breaks when model management and model use are granted to the same role?

A: Separation of duties breaks down.

Practitioner guidance

• Separate invocation from administration Create distinct roles for runtime model use and model configuration changes.
• Replace standing Bedrock access with short-lived access Issue temporary, task-scoped permissions for model invocation and expire them automatically.
• Map every invocation to a verified identity Correlate CloudTrail records to the authoritative human, service, or workload identity in your directory.

• Permission examples for Bedrock runtime, customization, and management actions that teams can map to their own IAM model
• AWS-specific governance patterns for cross-account invocation and resource-based policies in shared environments
• Practical guidance for linking model invocations back to federated users, service accounts, and workloads in CloudTrail
• Control scoping examples for aligning Bedrock usage with data classification and residency rules
