To remediate the misconfiguration “Service Account User Should Not Have Service Account Token Creator Role” for GCP using GCP CLI, you can follow the below steps:

1. Open the GCP Cloud Shell by clicking on the Activate Cloud Shell button on the top right corner of the GCP console.

2. Run the following command to list all the service accounts in your GCP project:

gcloud iam service-accounts list

3. Select the service account that you want to remediate and note its email address.

4. Run the following command to list all the roles assigned to the service account:

gcloud projects get-iam-policy <project-id> --flatten="bindings[].members" --format='table(bindings.role)' --filter="bindings.members:<service-account-email>"

Replace <project-id> with your GCP project ID and <service-account-email> with the email address of the service account that you want to remediate.

5. Check if the service account has the roles/iam.serviceAccountTokenCreator role assigned to it. If yes, then it needs to be removed.

6. Run the following command to remove the roles/iam.serviceAccountTokenCreator role from the service account:

gcloud projects remove-iam-policy-binding <project-id> --member="serviceAccount:<service-account-email>" --role="roles/iam.serviceAccountTokenCreator"

Replace <project-id> with your GCP project ID and <service-account-email> with the email address of the service account that you want to remediate.

7. Verify that the roles/iam.serviceAccountTokenCreator role has been removed from the service account by running the command in step 4 again.

By following these steps, you can remediate the misconfiguration “Service Account User Should Not Have Service Account Token Creator Role” for GCP using GCP CLI.

To remediate the misconfiguration “Service Account User Should Not Have Service Account Token Creator Role” for GCP using Python, follow these steps:

1. First, you need to identify the service account user who has the Service Account Token Creator role. You can do this by running the following command in the Cloud Shell:

   gcloud iam service-accounts list
   

2. Once you have identified the service account user, you need to remove the Service Account Token Creator role from the user. You can do this by running the following command in the Cloud Shell:

   from google.oauth2 import service_account
   from googleapiclient.discovery import build
   
   credentials = service_account.Credentials.from_service_account_file('<path_to_service_account_key_file>')
   service = build('iam', 'v1', credentials=credentials)
   
   user_email = '<service_account_user_email>'
   project_id = '<project_id>'
   role_name = 'roles/iam.serviceAccountTokenCreator'
   
   policy = service.projects().getIamPolicy(resource=project_id, body={}).execute()
   
   for binding in policy['bindings']:
       if binding['role'] == role_name and user_email in binding['members']:
           binding['members'].remove(user_email)
   
   service.projects().setIamPolicy(resource=project_id, body={'policy': policy}).execute()
   

   Note: Replace <path_to_service_account_key_file>, <service_account_user_email> and <project_id> with the appropriate values.

3. Once you have run the above command, verify that the Service Account Token Creator role has been removed from the service account user by running the following command in the Cloud Shell:

   gcloud projects get-iam-policy <project_id> --flatten="bindings[].members" --format='table(bindings.role)' --filter="bindings.members:<service_account_user_email>"
   

   This should return an empty table, indicating that the user no longer has the Service Account Token Creator role.

4. Finally, you should review your organization’s IAM policies and best practices to ensure that service account users are not granted unnecessary permissions in the future.
