1. Open the Google Cloud Console and select the project where the SQL instance is located.
2. In the left navigation menu, select SQL.
3. Select the SQL instance that you want to remediate.
4. In the SQL instance details page, click on the “Users” tab.
5. Review the list of users and check if there are any barred usernames (e.g., root, admin, etc.).
6. If there are any barred usernames, click on the username to select it.
7. Click on the “Delete” button to remove the user from the SQL instance.
8. Repeat steps 6 and 7 for all barred usernames.
9. Once all barred usernames have been removed, click on the “Add user account” button to create a new user account with a strong password.
10. Follow the prompts to create a new user account, ensuring that the username and password meet the recommended security standards.
11. Once the new user account has been created, click on the “Done” button to save the changes.

​

1. Open the Google Cloud Console and select the project where the SQL instance is located.
2. Open the Cloud Shell by clicking on the icon on the top right corner of the console.
3. In the Cloud Shell, run the following command to list all the SQL instances in the project:

4. Identify the SQL instance that is configured with barred usernames.
5. Run the following command to update the instance:

6. Verify that the configuration has been updated by running the following command:

7. Check the output for the ignore_builtin_usernames flag and verify that the barred usernames have been added to the list.
8. Repeat the above steps for all the SQL instances in the project that are configured with barred usernames.

1. First, you need to identify the SQL instances that are configured with barred usernames. You can use the GCP Python Client Library to list all the SQL instances in your project and check if any of them are configured with barred usernames.

from google.cloud import sql_v1beta4
from google.oauth2 import service_account

credentials = service_account.Credentials.from_service_account_file('path/to/credentials.json')
client = sql_v1beta4.CloudSqlInstancesServiceClient(credentials=credentials)

project_id = 'your-project-id'
instances = client.list(project_id=project_id)

2. Once you have identified the SQL instances that are configured with barred usernames, you need to update their configurations to remove the barred usernames. You can use the patch method of the CloudSqlInstancesServiceClient to update the instance configuration.

instance_name = 'your-instance-name'
instance = client.get(instance_name)
settings = instance.settings

if 'barred_usernames' in settings:
    del settings['barred_usernames']

update_mask = {'paths': ['settings']}
update_request = {'instance': {'settings': settings}, 'update_mask': update_mask}

operation = client.patch(instance_name, update_request)
operation.result()

3. Finally, you need to verify that the SQL instances are no longer configured with barred usernames. You can use the same code snippet from step 1 to list all the SQL instances and check their configurations.
