implementing-network-segmentation-with-firewall-zones

Designs and implements network segmentation using firewall security zones, VLANs, inter-zone ACLs, and workload-level microsegmentation to restrict east-west lateral movement and enforce least-privilege access. Use when architecting security zones, writing inter-zone firewall policies, or meeting PCI DSS/HIPAA/NIST 800-53/zero-trust segmentation requirements for dynamic or traditional network environments.
