Event Information

  • The cloudsql.instances.resetSslConfig event in GCP for CloudSQL refers to an event where the SSL configuration for a CloudSQL instance is reset.
  • This event typically occurs when there is a need to update or modify the SSL configuration settings for a CloudSQL instance.
  • Resetting the SSL configuration can involve actions such as generating new SSL certificates, updating SSL encryption protocols, or reconfiguring SSL connections for the CloudSQL instance.

​
Examples

  1. Insecure SSL/TLS communication: Resetting the SSL configuration for a CloudSQL instance in GCP can potentially impact security by allowing insecure SSL/TLS communication. This means that the data transmitted between the client and the database may be vulnerable to interception or tampering, leading to potential data breaches or unauthorized access.

  2. Lack of encryption: Resetting the SSL configuration may result in the absence of encryption for data in transit. Without SSL/TLS encryption, sensitive information such as usernames, passwords, and other data exchanged between the client and the CloudSQL instance can be exposed to eavesdropping or interception by malicious actors.

  3. Increased risk of man-in-the-middle attacks: Resetting the SSL configuration can create an opportunity for man-in-the-middle (MITM) attacks. In such attacks, an attacker intercepts the communication between the client and the database, posing as the legitimate server to capture or manipulate the data being transmitted. This can lead to unauthorized access, data leakage, or even the injection of malicious code into the communication stream.

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.
  1. 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.
  1. 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 in GCP CloudSQL using GCP CLI, you can follow these steps:

  1. Enable automatic backups:

    • Use the gcloud sql instances patch command to update the instance configuration.
    • Specify the --backup-start-time flag to set a specific time for backups to start.
    • Example command: gcloud sql instances patch INSTANCE_NAME --backup-start-time HH:MM

  2. Enable SSL/TLS encryption for connections:

    • Use the gcloud sql instances patch command to update the instance configuration.
    • Specify the --require-ssl flag to enforce SSL/TLS encryption for connections.
    • Example command: gcloud sql instances patch INSTANCE_NAME --require-ssl

  3. Enable VPC Service Controls:

    • Use the gcloud services enable command to enable the VPC Service Controls API.
    • Example command: gcloud services enable vpcaccess.googleapis.com

Note: Replace INSTANCE_NAME with the actual name of your CloudSQL instance.

​
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.
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()
  1. 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.
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()
  1. 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.
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.
