Description​

Database servers should accept connections only from trusted networks or IPs and restrict access from public IP addresses.

Rationale​

To minimize the attack surface on a database server instance, only trusted and required IPs should be allowlisted to connect to it.

An authorized network should not have IPs/networks configured to 0.0.0.0/0 which will allow access to the instance from anywhere in the world. Note that authorized networks apply only to instances with public IPs.

Impact​

The Cloud SQL database instance would not be available to public IP addresses.

Audit​

From Google Cloud Console​
  1. Go to the Cloud SQL Instances page in the Google Cloud Console by visiting https://console.cloud.google.com/sql/instances.
  2. Click the instance name to open its Instance details page.
  3. Under the Configuration section click Edit configurations.
  4. Under Configuration options expand the Connectivity section.
  5. Ensure that no authorized network is configured to allow 0.0.0.0/0.
From Google Cloud CLI​
