aws-posture Read-only AWS posture check — public exposure, IAM blast radius, hygiene

Check the live AWS account's security posture using strictly read-only CLI calls, then fix root causes in the IaC.

HARD RULE: read-only means read-only — describe/list/get/simulate calls only. No create/put/update/delete/attach, no terraform apply, ever. If a fix is needed, it goes into Terraform for the team to apply.

  1. Confirm access and scope: aws sts get-caller-identity (mask the account id to its last 4 digits in anything you write). Ask which regions matter; default to the ones the Terraform state uses.
  2. Sweep the high-signal surfaces, most exposed first:
    • Public entry points: S3 buckets (get-public-access-block, bucket policies), security groups open to 0.0.0.0/0 on sensitive ports, public RDS/ES endpoints, ALB listeners without TLS.
    • IAM blast radius: users with attached admin policies, wildcard Action/Resource in customer-managed policies, stale access keys (iam get-credential-report), roles with overly broad trust policies.
    • Hygiene: CloudTrail on and multi-region, default EBS/S3 encryption, root-account MFA (from the credential report).
  3. Cross-reference each finding against the repo's Terraform: is the risky config defined in code (fix it there), drifted from code (flag the drift), or unmanaged (propose importing it)?
  4. Deliver: an exposure-ranked posture report (finding · resource · evidence command · where it's defined · action), the IaC fix branch for what's code-managed, and a short list of items needing a human decision. Every claim carries the exact read-only command that evidences it, so the team can re-run and verify.
