Workload identity federation in GCP - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is Workload Identity Federation in Google Cloud?

Workload Identity Federation lets your applications outside Google Cloud securely access Google Cloud resources without using long-lived service account keys.

beginner

How does Workload Identity Federation improve security compared to service account keys?

It avoids storing and managing long-lived keys by using short-lived tokens from external identity providers, reducing risk of key leaks.

intermediate

Which external identity providers can be used with Workload Identity Federation?

Common providers include AWS, Azure, OIDC-compatible providers like Okta, and any provider that supports OpenID Connect tokens.

What is the role of a Workload Identity Pool in federation?

A Workload Identity Pool groups external identities and lets you define trust relationships and permissions for those identities to access Google Cloud.

advanced

Describe the main steps to configure Workload Identity Federation for an external workload.

1. Create a Workload Identity Pool in Google Cloud. 2. Add a provider that trusts your external identity. 3. Create a service account and grant it roles. 4. Configure your external workload to request tokens from the provider and exchange them for Google credentials.

What does Workload Identity Federation replace in Google Cloud authentication?

A OAuth client secrets

B User passwords

C Long-lived service account keys

D API keys

Workload Identity Federation replaces the need for long-lived service account keys by using short-lived tokens from external identity providers.

Which protocol is commonly used by external identity providers in Workload Identity Federation?

A OpenID Connect (OIDC)

B FTP

C SMTP

D SOAP

OpenID Connect (OIDC) is the standard protocol used for identity federation with Google Cloud.

What is a Workload Identity Pool used for?

A Storing service account keys

B Configuring network firewalls

C Managing virtual machines

D Grouping external identities for trust and access control

A Workload Identity Pool groups external identities and defines trust relationships for access.

Which of the following is NOT a benefit of Workload Identity Federation?

A Requires manual rotation of keys every 30 days

B Allows external workloads to access Google Cloud securely

C Eliminates need to manage service account keys

D Uses short-lived tokens for authentication

Workload Identity Federation removes the need for manual key rotation by avoiding long-lived keys.

To use Workload Identity Federation, you must first:

A Create a Google Cloud Storage bucket

B Create a Workload Identity Pool in Google Cloud

C Enable the Compute Engine API

D Generate a service account key file

Creating a Workload Identity Pool is the first step to set up federation.

Explain how Workload Identity Federation enhances security for external workloads accessing Google Cloud.

Think about how keys and tokens differ in security.

Describe the main components and steps involved in setting up Workload Identity Federation in Google Cloud.

Consider the flow from external identity to Google Cloud access.
