What you are evaluating
This entry covers Policy with AgentCore Gateway, not the entire Bedrock portfolio. Calls that bypass the gateway need their own controls. Bedrock Guardrails is a separate content-inspection service, and neither product automatically grants appropriate downstream credentials.
A useful evaluation context
Agent builders need deterministic limits on actions, especially when investigation agents can read evidence containing untrusted instructions.
Documented capabilities
The vendor describes these capabilities in the linked sources. Availability depends on the product edition and supported environment.
- Cedar policies permit or forbid scoped gateway tool actions under explicit conditions.
- An enforced policy engine denies requests without an applicable permit; a matching forbid takes precedence.
- Gateway execution and resource-management roles have different IAM responsibilities.
Where it fits in the work
- Put a harmless test tool behind a gateway and identify the calling principal.
- Review a narrowly scoped policy and attach the engine in enforce mode.
- Test allowed, forbidden and unmatched calls, then verify the downstream service sees only allowed actions.
APPLY THE IDEA / ILLUSTRATIVE EXERCISE
Make the outcome observable.
Give an educational Agentic SOC worker a read-evidence tool and a simulated containment tool with no permit.
Evidence to look for
The authorized read succeeds, containment is denied at the gateway, and the downstream mock records no containment action.
Use synthetic data and an authorized test environment. Agree the scope and recovery steps before enabling enforcement.
Questions for your evaluation
- Can the agent reach the same API without going through the gateway?
- Are policy inputs derived from trusted identity claims or editable model arguments?
- What privileges does the gateway execution role retain after a request is authorized?
