Implementing Least Privilege IAM Policy Bindings in Cloud Run

In Cloud Run, if a service is deployed without specifying a service account, a default service account is used. The default service account used is the Compute Engine service account which has the broad Editor role on the project. Because of policy binding inheritance, this service account has read and write permissions on most resources in your project. While convenient, it’s an inherent security risk as resources can be created, modified, or deleted with this service account.

To mitigate this risk and implement the principle of least privilege, you should create a service account that serves as the service’s identity, and grant the minimum set of permissions to the account that are required for the service’s functionality.

Configure your environment and enable the Cloud Run API.
Create and deploy a public Cloud Run service.
Test the service with unauthenticated requests.
Create a service account with minimum permissions.
Use the gcloud CLI to authenticate with the service account, and invoke a Cloud Run service.
Implement least privilege by granting the minimum set of permissions required to invoke a service on Cloud Run.

Configure the environment

Set up environment variables in Cloud Shell to make the provisioning process more flexible.

Requirements

Quickway parking has a Cloud Run billing service that they would like to be made more secure. In this task, you:

Deploy the billing service from an image.
Test the service by invoking it without any authentication.

Deploying with Cloud Run

The Quickway development team already has an image of the billing application available on Google Cloud.

To go back to the service details page, click <- Service details.

Select the billing-service by checking the box to the left of the green check mark.

This resource is public and can be accessed by anyone on the internet. To remove public access, remove "allUsers" and "allAuthenticatedUsers" from the resource's principals. 

The Security team has spotted something in the security settings. Can you see what part of the above configuration has them so concerned?

Take a closer look at the authentication applied. Currently anyone on the internet can call the billing service. This is indicated by the allUsers identity that has the Cloud Run Invoker role.

When the Billing service was originally deployed, it used the --allow-unauthenticated permission, which means that the service is publicly accessible, and can be invoked without any authentication.

By removing the --allow-unauthenticated permission you can use the Cloud Run default permissions to secure the service, or you can explicitly specify the no-allow-unauthenticated permission.

By making these changes, the Security team will be a lot happier with the overall design.

Authenticating service requests

The team updates the application design to show how the changes will work:

The main changes are:

Remove unauthenticated public access to the billing service.
Create a new service account with appropriate permissions to invoke the billing service.

Update the service to require authentication

Delete the existing deployed service:

student_01_e488ef31cb8a@cloudshell:~ (qwiklabs-gcp-00-cbf0411caa40)$  gcloud run services delete billing-service
Service [billing-service] will be deleted.

student_01_e488ef31cb8a@cloudshell:~ (qwiklabs-gcp-00-cbf0411caa40)$ 

Redeploying the service means it no longer allows unauthenticated access at its service URL. In addition, the access permission to invoke the service has been removed.

Wait a few seconds, and then invoke the billing service again as before:

student_01_e488ef31cb8a@cloudshell:~ (qwiklabs-gcp-00-cbf0411caa40)$  curl -X POST -H "Content-Type: application/json" $BILLING_SERVICE_URL -d '{"userid": "1234", "minBalance": 100}'

<body text=#000000 bgcolor=#ffffff>
<h1>Error: Forbidden</h1>

<h2></h2>
</body></html>
student_01_e488ef31cb8a@cloudshell:~ (qwiklabs-gcp-00-cbf0411caa40)$ 

As expected, the output is a permissions error since the service now requires authentication.

Now that you understand more about the permissions used with Cloud Run, correct the authentication permissions applied to the Billing service:

Create a service account

To invoke the billing service you will need an identity or service account with appropriate permissions, and bind that identity to the service.

This can be done in the Google Cloud console, or with the gcloud command line interface. In this lab, you use the Google Cloud console to create the service account and set up the new policy binding for the billing service.

In the Google Cloud console Navigation menu (), select IAM & Admin > Service Accounts.
To create a new service account that will provide authenticated access, click Create Service Account near the top.
Name the service account: Billing Initiator.
To create the account, click Create and Continue, and then advance to the Grant Access step.

To give the Billing Initiator service account permissions to invoke the billing service, select the Role drop-down, scroll the left side to Cloud Run, and then select the role Cloud Run Invoker.
To complete the setup of the service account, click Continue, and then click Done.

You will see the new service account at the top of the list of service accounts in the console.

The service account Billing Initiator has been created with the authorization to invoke a Cloud Run service, using an IAM policy binding on your project.

Invoke the service with authentication

Now that you have a service account with the appropriate permission, you can use it to invoke your Cloud Run service.

Authenticate with gcloud

The first step is to set the service account in gcloud so it can be used to authenticate with the service.

In the Cloud Shell terminal menu, open a new shell in a separate tab by clicking Add ().

Execute the remaining commands of this task in this Cloud Shell window.
Get the service account identity email and save it in an environment variable:

Implement least privilege

You’ve used a service account with the appropriate permissions to invoke a Cloud Run service that was previously accessible by anyone. But, have you used the absolute minimum privileges needed to call this specific service?

To determine if this is true, deploy a second billing service which we will assume should be accessible only by other internal private services, such as Cloud Scheduler.

Deploy a second service

Open a third Cloud Shell terminal window or tab.
Create a LOCATION environment variable:
To simulate a second service, deploy the billing application image to Cloud Run:

student_01_e488ef31cb8a@cloudshell:~ (qwiklabs-gcp-00-cbf0411caa40)$ 

Assign the URL of the new service to an environment variable:

student_01_e488ef31cb8a@cloudshell:~ (qwiklabs-gcp-00-cbf0411caa40)$ 

Invoke the second service with the service account identity

In this third Cloud Shell terminal, authorize access to Cloud Run with the same service account:

student_01_e488ef31cb8a@cloudshell:~ (qwiklabs-gcp-00-cbf0411caa40)$ gcloud auth activate-service-account --key-file=key.json
Activated service account credentials for: [billing-initiator@qwiklabs-gcp-00-cbf0411caa40.iam.gserviceaccount.com]

  -H "Authorization: Bearer $(gcloud auth print-identity-token)" \
  $BILLING_SERVICE_2_URL -d '{"userid": "1234", "minBalance": 900}'
student_01_e488ef31cb8a@cloudshell:~ (qwiklabs-gcp-00-cbf0411caa40)$ 

Why was this successful!? It’s because when you created the service account, the Cloud Run Invoker permissions were granted to this account on the project. Because of inheritance, resources in the project such as the two Cloud Run services inherit those permissions, and as a result, the service account can be used to invoke the services.

Restrict service account permissions

To fully implement least privilege, the service account should only be granted permissions on the service that it needs.

In this subtask, you remove the permission previously granted to the service account on the project, and then add the appropriate permissions required to invoke the original billing service.

Switch to the first Cloud Shell terminal window.
In this Cloud Shell terminal, get the service account identity email and save it in an environment variable:

Invoke the services

Switch back to the second Cloud Shell terminal window or tab.
Wait a few seconds, and then invoke the first Cloud Run billing service with an identity token generated from the service account:

student_01_e488ef31cb8a@cloudshell:~ (qwiklabs-gcp-00-cbf0411caa40)$  curl -X POST -H "Content-Type: application/json" \
  -H "Authorization: Bearer $(gcloud auth print-identity-token)" \
  $BILLING_SERVICE_URL -d '{"userid": "1234", "minBalance": 700}'
student_01_e488ef31cb8a@cloudshell:~ (qwiklabs-gcp-00-cbf0411caa40)$ 

It takes a few seconds for the updated permissions to propagate, after which this invocation should be successful.

Switch to the third Cloud Shell terminal window.

Try to invoke the second Cloud Run service with an identity token generated from the same service account:

student_01_e488ef31cb8a@cloudshell:~ (qwiklabs-gcp-00-cbf0411caa40)$  curl -X POST -H "Content-Type: application/json" \
  -H "Authorization: Bearer $(gcloud auth print-identity-token)" \
  $BILLING_SERVICE_2_URL -d '{"userid": "1234", "minBalance": 500}'

<html><head>
<meta http-equiv="content-type" content="text/html;charset=utf-8">

<body text=#000000 bgcolor=#ffffff>
<h1>Error: Forbidden</h1>
<h2>Your client does not have permission to get URL <code>/</code> from this server.</h2>
<h2></h2>
</body></html>
student_01_e488ef31cb8a@cloudshell:~ (qwiklabs-gcp-00-cbf0411caa40)$ 

You should now receive a permissions error indicating that the service account has only the minimum set of permissions required to invoke the first service.

In this lab, you have seen how to reconfigure a deployed service to secure access to it, and implemented the principle of least privilege when granting permissions to access resources on Google Cloud. You:

Deployed a service to Cloud Run.
Used the gcloud CLI to update the service to require authentication.
Created a service account with the required permissions to invoke the service.
Set the minimum permissions required to invoke a specific service on Cloud Run, implementing least privilege.

Here’s a diagram of this requirement:
