Improve instance security by enforcing SSL/TLS encryption

MySQL  |  PostgreSQL  |  SQL Server

This page describes how to view and implement recommendations about configuringinstance settings to enforce SSL/TLS encryption requirements for direct connections. Encryption helps ensure secure data transfer. Thisrecommender is calledRequire SSL.

Every day, this recommender proactively detects instances that don'tenforce encryption requirements for direct connections and provides insights and recommendations to improveyour instance security. You can view insights and detailed recommendations aboutthese instances by using the Google Cloud console,gcloud CLI, or theRecommender API.

Before you begin

Ensure that youenable the Recommender API.

Required roles and permissions

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