Network Security Groups

Configures network security groups and firewall rules across AWS, GCP, and Kubernetes to control traffic flow and enforce network segmentation. You'll reach for this when setting up multi-tier applications, restricting database access, or implementing zero-trust networking. The reference guides cover Security Groups in AWS, Network Policies in Kubernetes, and GCP Firewall Rules with working YAML examples. The best practices section hammers home the important stuff: never expose databases to 0.0.0.0/0, document every rule's purpose, and use security group references instead of hardcoded IPs. It's comprehensive enough to get proper network isolation running without having to piece together documentation from three different cloud providers.
