Improve instance security by enforcing SSL/TLS encryption

This page describes how to view and implement recommendations about configuring instance settings to enforce SSL/TLS encryption requirements for direct connections. Encryption helps ensure secure data transfer. This recommender is called Require SSL.

Every day, this recommender proactively detects instances that don't enforce encryption requirements for direct connections and provides insights and recommendations to improve your instance security. You can view insights and detailed recommendations about these instances by using the Google Cloud console, gcloud CLI, or the Recommender API.

Before you begin

Ensure that you enable the Recommender API.

Required roles and permissions

To get the permissions to view and work with insights and recommendations, ensure that you have the required Identity and Access Management (IAM) roles.

Tasks Roles
View recommendations recommender.cloudsqlViewer or cloudsql.admin.
Apply recommendations cloudsql.editor or cloudsql.admin.
For more information about IAM roles, see IAM basic and predefined roles reference and Manage access to projects, folders, and organizations.

  • LOCATION: A region where your instances are located, such as us-central1.

API

Call the recommendations.list method as follows:

GET https://recommender.googleapis.com/v1beta1/projects/PROJECT_ID/locations/LOCATION/recommenders/google.cloudsql.instance.SecurityRecommender/recommendations?filter=recommenderSubtype=REQUIRE_SSL

Replace the following:

  • PROJECT_ID: Your project ID.
  • LOCATION: A region where your instances are located, such as us-central1.

View insights and detailed recommendations

To view insights and detailed recommendations, follow these steps:

Console

On the Security Recommendations page, click the recommendation for an instance. The recommendation panel appears, which contains insights and detailed recommendations.

gcloud

Run the gcloud recommender insights list command as follows:


gcloud recommender insights list \
--project=PROJECT_ID \
--location=LOCATION \
--insight-type=google.cloudsql.instance.SecurityInsight \
--filter=insightSubtype=SSL_NOT_REQUIRED

Replace the following:

  • PROJECT_ID: Your project ID.
  • LOCATION : A region where your instances are located, such as us-central1.

API

Call the insights.list method as follows:


GET https://recommender.googleapis.com/v1beta1/projects/PROJECT_ID/locations/LOCATION/insightTypes/google.cloudsql.instance.SecurityInsight/insights?filter=insightSubtype=SSL_NOT_REQUIRED
