Description

Database Server should accept connections only from trusted Network(s)/IP(s) and restrict access from public IP addresses.

Rationale

To minimize attack surface on a Database server instance, only trusted/known and required IP(s) should be white-listed 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.
