This intermediate module explores the foundational elements of cloud networking security, focusing on Virtual Private Cloud (VPC) architecture. You will learn how to design secure network topologies, identify common misconfigurations like overly permissive route tables and exposed public subnets, and implement strict network segmentation to prevent lateral movement. The curriculum covers subnetting, Internet Gateways, NAT Gateways, and VPC Flow Logs, providing the essential knowledge required to build, monitor, and defend resilient cloud network perimeters against modern attack techniques.
