Authorization Gap in AI Ops: Building a EKS Control Plane
Explore security gaps in AI Operations, separating reasoning from authority, and using Cedar and AWS Step Functions to protect EKS clusters.

- AI reasoning capability does not equate to operational authorization authority.
- Separating model proposals from deterministic infrastructure evidence collectors is crucial.
- Amazon Verified Permissions with Cedar enables robust default-deny policy enforcement.
- AWS Step Functions orchestrate workflows while mitigating time-of-check issues.
The hardest problem in AI-driven operations is not getting an agent to diagnose an incident. Modern models can correlate logs, metrics, deployment events, traces, Kubernetes state, and historical incidents well enough to produce plausible remediation proposals. The harder question begins one step later: who decides whether the proposed action is actually allowed to touch production?
That distinction matters because reasoning quality and operational authority are different properties. An agent can be highly accurate and still eventually make a bad decision. If that decision carries unrestricted production authority, model accuracy becomes a weak safety boundary. A better architecture assumes that recommendations can be wrong and constrains what happens when they are.

From a systems engineering perspective, this architecture reflects core principles of Least Privilege and Zero Trust. Allowing an LLM to execute raw operational instructions without an external policy enforcement layer creates significant security risks. Leveraging Cedar to externalize and strictly evaluate authorization provides a critical safeguard against autonomous overreach.
The important architectural decision is not which model sits at the top. It is that the model does not own the bottom half. An operations agent should never hand an executor a natural-language instruction without strict parameters and structured intent.

The model may propose a rollback target revision, but it should not be trusted to assert system health or migration safety autonomously. Those underlying facts need to come from deterministic systems and a separate evidence collector enriching the operational request.
Amazon Verified Permissions is useful here because it externalizes authorization decisions into policies written in Cedar. Cedar also supports explicit forbid policies and a default-deny evaluation model, making safety boundaries straightforward for critical actions like deleting persistent data or modifying infrastructure settings.
AWS Step Functions fits naturally to orchestrate remediation state machines, supporting the callback-with-task-token pattern for human approvals. However, because production state can drift during a human review window, recollecting critical evidence and re-evaluating authorization immediately before execution is essential to solve time-of-check versus time-of-use problems.
