Zorluk: ZorManaging IAM Roles and Permissions

An automated deployment process requires access to upload build artifacts as new files into a specific Cloud Storage bucket named `prod-build-artifacts` located inside the project `app-deployments-prod`. According to organization security compliance, the process must adhere strictly to the Principle of Least Privilege by ensuring it cannot read existing objects, overwrite/delete files, or access any other buckets in the project or parent folder. Which IAM role assignment strategy should be configured?

  1. Grant the predefined role Storage Object Creator (roles/storage.objectCreator) on the specific prod-build-artifacts bucket resource.Cevap
  2. B
    Grant the primitive role Editor (roles/editor) at the app-deployments-prod project level.
  3. C
    Grant the predefined role Storage Object Creator (roles/storage.objectCreator) at the parent Folder level containing app-deployments-prod.
  4. D
    Grant the primitive role Viewer (roles/viewer) on the prod-build-artifacts bucket resource.

Cevap

Grant the predefined role Storage Object Creator (roles/storage.objectCreator) specifically on the target Cloud Storage bucket resource.
Granting `roles/storage.objectCreator` directly on the target Cloud Storage bucket grants only the necessary `storage.objects.create` permission specifically on that bucket. It prevents reading existing objects, deleting data, and accessing any other buckets in the project or folder hierarchy.

Adım Adım Çözüm

1
Analyze required permissions
The requirement mandates object upload (create) capability only, prohibiting object read, list, delete, or access to other storage resources.
Security rules enforce the Principle of Least Privilege.
2
Select the appropriate IAM role type
Select predefined role `roles/storage.objectCreator` over primitive roles (`roles/editor`, `roles/viewer`).
Predefined roles provide granular, narrow permissions tailored specifically to exact operational needs.
3
Determine the resource hierarchy binding level
Bind the role directly to the bucket resource `prod-build-artifacts` rather than at the project or folder level.
Permissions inherit down the hierarchy, so binding at project or folder levels grants unauthorized access to other buckets.
