Layered IAM roles with permission boundaries, explicit denies, and cross‑cloud mirroring enforce least privilege while keeping auditability.
Set up IAM Identity Center with Okta or Azure AD via SAML, map groups to permission sets, and assign them using AWS CLI; watch for propagation delay.
GCP Workload Identity Federation and AWS IRSA replace static keys with short‑lived tokens via OIDC providers and K8s service‑account bindings, enforcing least‑privilege access.
Use IAM Access Analyzer’s UNUSED_IAM_CREDENTIAL findings with CLI/SDK to locate and delete stale keys, passwords, and certificates, automating via Lambda.
Enforce least‑privilege policies, condition‑based denies, and continuous IAM audits to block privilege escalation.
SCPs are org‑wide guardrails that cap IAM permissions, evaluated before IAM policies and can only tighten access.
