AWS IAM security best practices for workload identities

Use this guide to review machine identity design: favor short-lived role credentials for workloads, limit permissions to required actions and resources, and retire unnecessary access. It also explains policy validation, access reviews, and organizational guardrails that help keep workload access aligned with its purpose.

How to use this reference

Compare an owned workload’s documented identity lifecycle and minimum permission needs with the guide, recording unnecessary access for review.

Before reading

  • Basic understanding of cloud workloads, roles, and identity policies
  • Familiarity with authentication versus authorization

Context and limits

  • AWS-managed policies may need further narrowing for a specific workload.
  • Organization-level guardrails constrain permissions; they do not grant access by themselves.

Related visual models

A verified workload identity and a requested operation enter an independent authorization decision. Policy checks the role, action, resource and tenant together. Only the approved resource scope is allowed; other requests are denied. Both decisions produce an audit record.

Conceptual model Diagram

Keep workload authority tenant-scoped
