In the Secure Networks for Databases course, you will learn to design, implement, and audit secure network architectures for Google Cloud database services. You will configure Private Service Connect (PSC) and VPC Network Peering for private database communication, implement Identity-Aware Proxy (IAP) TCP forwarding for secure administrative access without public IPs, analyze network traffic using VPC Flow Logs, and enforce strict identity-based access control and egress lockdowns using firewall rules and the Cloud SQL Auth Proxy with IAM authentication.
