info:
  name: Cloud SQL Database Instances with Public IPs
  author: princechaddha
  severity: medium
  description: |
    Ensure that your Google Cloud SQL database instances are configured to use private IP addresses instead of public IPs to protect against potential security risks and unauthorized access.
  impact: |
    Database instances with public IP addresses are exposed to the internet, increasing the risk of unauthorized access and potential attacks.
  remediation: |
    Configure your Cloud SQL database instances to use private IP addresses to limit exposure to external networks and enhance security.
