GCP IAM Project-Level Role Binding

The grant applies to every resource in the project rather than the one it was needed for, so access is far wider than anyone intended.

01

Detect

ZopNight checks this automatically across Google Cloud, with read-only access to the account.

02

Explain

Every finding says exactly what to change: Scope IAM role to resource level.

03

Fix

The finding opens with the fix already written out, step by step, so it is one ticket, not an investigation.

Applies to
Any resource in the account
The fix, by hand
  1. List project-level role bindings that affect ‹name›: gcloud projects get-iam-policy ‹project› --format=json | jq '.bindings[]'.
  2. For each broad binding (roles/editor, roles/owner, roles/viewer at project scope), identify which principals actually need access to which resources.
  3. Re-bind at the resource level instead: gcloud ‹service› add-iam-policy-binding ‹name› --member=user:foo@example.com --role=roles/‹specific›.
  4. Remove the project-level binding: gcloud projects remove-iam-policy-binding ‹project› --member=... --role=roles/editor.
  5. Use IAM Recommender (Cloud Console → IAM and Admin → IAM → Recommendations column) to find right-sized roles automatically.
  6. Set Org Policy constraints/iam.automaticIamGrantsForDefaultServiceAccounts = enforced to stop new broad bindings.

These are the steps the finding carries in the product.
