GCP Terraform Misconfiguration: Compute Engine Default Service Account
Abstract
Terraform 組態會建立一個具有預設服務帳戶的 Compute Engine 執行個體。
Explanation
如果建立的 Compute Engine 執行個體沒有使用者管理的服務帳戶規格,Google Cloud 會將預設服務帳戶指派給該執行個體。預設服務帳戶的存取權往往超出執行個體運作所需的權限,這會違反最小特權原則。
範例 1:以下範例顯示一個會建立 Compute Engine 執行個體的 Terraform 組態,但這個執行個體沒有使用者管理的服務帳戶規格。
