# Cloudsql.instances.delete remediation

### Event Information

* The cloudsql.instances.delete event in GCP for CloudSQL indicates that a Cloud SQL instance has been deleted.
* This event is triggered when a user or an automated process initiates the deletion of a Cloud SQL instance.
* The event provides information about the instance that was deleted, such as the instance ID, project ID, and region.

### Examples

1. Unauthorized deletion: If security is impacted with cloudsql.instances.delete in GCP for CloudSQL, one example could be an unauthorized user gaining access to the CloudSQL instance and deleting it. This could result in the loss of critical data and disrupt the availability of the application relying on the database.

2. Data breach: Another example could be a malicious actor exploiting a vulnerability in the CloudSQL instance and using the delete operation to remove the database. This could lead to a data breach, exposing sensitive information to unauthorized individuals.

3. Denial of Service (DoS): A third example could be an attacker launching a DoS attack by repeatedly deleting and recreating the CloudSQL instance. This could overwhelm the system, causing it to become unresponsive and impacting the availability of the application.

### Remediation

#### Using Console

1. Enable automatic backups:

* Go to the GCP Console and navigate to the Cloud SQL instances page.
* Select the instance for which you want to enable automatic backups.
* Click on the "Edit" button.
* Scroll down to the "Backup" section and check the box next to "Automated backups".
* Set the desired backup retention period.
* Click on the "Save" button to apply the changes.

2. Enable SSL/TLS encryption for connections:

* Go to the GCP Console and navigate to the Cloud SQL instances page.
* Select the instance for which you want to enable SSL/TLS encryption.
* Click on the "Edit" button.
* Scroll down to the "Connections" section and check the box next to "Require SSL".
* Choose the appropriate SSL/TLS certificate option.
* Click on the "Save" button to apply the changes.

3. Enable VPC Service Controls:

* Go to the GCP Console and navigate to the VPC Service Controls page.
* Click on the "Create Perimeter" button.
* Provide a name and description for the perimeter.
* Select the project and location where the Cloud SQL instance is located.
* Add the Cloud SQL API to the list of services allowed within the perimeter.
* Configure the desired access levels and conditions.
* Click on the "Create" button to create the perimeter.
* Associate the perimeter with the Cloud SQL instance by going to the Cloud SQL instances page, selecting the instance, clicking on the "Edit" button, and selecting the perimeter from the "VPC Service Controls" section.
* Click on the "Save" button to apply the changes.

#### Using CLI

To remediate the issues mentioned in the previous response for GCP CloudSQL using GCP CLI, you can follow these steps:

1. Enable automatic backups:
   * Use the following command to enable automatic backups for a CloudSQL instance:
     ```
     gcloud sql instances patch INSTANCE_NAME --backup-start-time START_TIME
     ```
     Replace `INSTANCE_NAME` with the name of your CloudSQL instance and `START_TIME` with the desired backup start time.

2. Configure SSL/TLS encryption:
   * Use the following command to configure SSL/TLS encryption for a CloudSQL instance:
     ```
     gcloud sql instances patch INSTANCE_NAME --require-ssl
     ```
     Replace `INSTANCE_NAME` with the name of your CloudSQL instance.

3. Enable VPC Service Controls:
   * Use the following command to enable VPC Service Controls for a CloudSQL instance:
     ```
     gcloud beta sql instances update INSTANCE_NAME --enable-vpc-service-controls --network NETWORK_NAME --subnet SUBNET_NAME
     ```
     Replace `INSTANCE_NAME` with the name of your CloudSQL instance, `NETWORK_NAME` with the name of your VPC network, and `SUBNET_NAME` with the name of your subnet.

Please note that these commands assume you have the necessary permissions to make changes to the CloudSQL instances. Make sure to replace the placeholders with the appropriate values specific to your environment.

#### Using Python

To remediate the issues mentioned in the previous response for GCP CloudSQL using Python, you can follow these steps:

1. Enable automatic backups:
   * Use the `googleapiclient` library to interact with the Cloud SQL API.
   * Use the `instances().get()` method to retrieve the current configuration of the Cloud SQL instance.
   * Set the `backupConfiguration.enabled` field to `True` to enable automatic backups.
   * Use the `instances().update()` method to update the Cloud SQL instance with the new configuration.

```python theme={null}
from googleapiclient import discovery
from oauth2client.client import GoogleCredentials

credentials = GoogleCredentials.get_application_default()
service = discovery.build('sqladmin', 'v1beta4', credentials=credentials)

project_id = 'your-project-id'
instance_name = 'your-instance-name'

instance = service.instances().get(project=project_id, instance=instance_name).execute()
instance['settings']['backupConfiguration']['enabled'] = True

service.instances().update(project=project_id, instance=instance_name, body=instance).execute()
```

2. Enable SSL/TLS encryption:
   * Use the `googleapiclient` library to interact with the Cloud SQL API.
   * Use the `instances().get()` method to retrieve the current configuration of the Cloud SQL instance.
   * Set the `settings.ipConfiguration.requireSsl` field to `True` to enforce SSL/TLS encryption.
   * Use the `instances().update()` method to update the Cloud SQL instance with the new configuration.

```python theme={null}
from googleapiclient import discovery
from oauth2client.client import GoogleCredentials

credentials = GoogleCredentials.get_application_default()
service = discovery.build('sqladmin', 'v1beta4', credentials=credentials)

project_id = 'your-project-id'
instance_name = 'your-instance-name'

instance = service.instances().get(project=project_id, instance=instance_name).execute()
instance['settings']['ipConfiguration']['requireSsl'] = True

service.instances().update(project=project_id, instance=instance_name, body=instance).execute()
```

3. Enable VPC Service Controls:
   * Use the `googleapiclient` library to interact with the Access Context Manager API.
   * Use the `accessPolicies().get()` method to retrieve the current configuration of the access policy.
   * Set the `servicePerimeters[].resources[].services[].vpcAccessibleServices[].enableRestriction` field to `True` for Cloud SQL.
   * Use the `accessPolicies().update()` method to update the access policy with the new configuration.

```python theme={null}
from googleapiclient import discovery
from oauth2client.client import GoogleCredentials

credentials = GoogleCredentials.get_application_default()
service = discovery.build('accesscontextmanager', 'v1', credentials=credentials)

access_policy_name = 'your-access-policy-name'
service_perimeter_name = 'your-service-perimeter-name'

access_policy = service.accessPolicies().get(name=access_policy_name).execute()
for service_perimeter in access_policy['servicePerimeters']:
    if service_perimeter['name'] == service_perimeter_name:
        for resource in service_perimeter['resources']:
            if resource['service'] == 'sqladmin.googleapis.com':
                resource['vpcAccessibleServices'][0]['enableRestriction'] = True

service.accessPolicies().update(name=access_policy_name, body=access_policy).execute()
```

Please note that you need to replace `'your-project-id'`, `'your-instance-name'`, `'your-access-policy-name'`, and `'your-service-perimeter-name'` with the actual values specific to your environment.
