Zorluk: OrtaCreating and Managing Service Accounts

A cloud administrator needs to grant an external automated system temporary access to collect metrics from Compute Engine instances within a Google Cloud project. To adhere to Google Cloud security standards, the administrator must avoid generating and downloading long-lived service account JSON keys. Which implementation strategy should the administrator select?

  1. Create a dedicated service account with the predefined Monitoring Viewer role and configure Workload Identity Federation to issue short-lived credentials to the external system.Cevap
  2. B
    Create a service account with the Monitoring Viewer role, export a JSON private key, and store the key in Google Cloud Secret Manager for the external service to retrieve.
  3. C
    Create a service account, assign it the primitive Owner role at the project level, and configure short-lived service account impersonation for the external system.
  4. D
    Grant the external system's identity the Monitoring Viewer role at the organization level, expecting explicit deny policies on unneeded child projects to restrict access.

Cevap

Create a dedicated service account with the predefined Monitoring Viewer role and configure Workload Identity Federation to issue short-lived credentials to the external system.
The correct strategy uses a dedicated service account bound strictly to the required predefined role (Monitoring Viewer) and uses Workload Identity Federation to grant short-lived access without creating long-lived private key files.

Adım Adım Çözüm

1
Identify the required level of access for metric collection
The predefined role roles/monitoring.viewer provides read access to monitoring metrics under the principle of least privilege.
Primitive roles like Owner grant excessive permissions beyond what is needed.
2
Determine the authentication mechanism for workloads outside Google Cloud
Workload Identity Federation allows external workloads to exchange credentials from external identity providers for short-lived Google Cloud service account tokens.
Exporting long-lived service account JSON keys creates maintenance overhead and security risks associated with credential leakage.
