# Implementing Network Segmentation with Firewall Zones
## Overview
Network segmentation divides a flat network into isolated security zones with firewall-enforced boundaries to contain breaches, restrict lateral movement, and enforce least-privilege access between workloads. Segmentation is a foundational control required by PCI DSS, HIPAA, NIST 800-53, and zero trust architectures. Modern segmentation combines traditional VLAN-based approaches with microsegmentation at the workload level for granular east-west traffic control. This skill covers designing zone architectures, configuring inter-zone firewall policies, implementing VLAN segmentation on switches, and deploying microsegmentation for dynamic environments.
## When to Use
- When deploying or configuring implementing network segmentation with firewall zones capabilities in your environment
- When establishing security controls aligned to compliance requirements
- When building or improving security architecture for this domain
- When conducting security assessments that require this implementation
