# Configuring Microsegmentation for Zero Trust ## Prerequisites - Understanding of zero trust principles (NIST SP 800-207) - Knowledge of network segmentation concepts - Familiarity with firewall and SDN technologies - Experience with VMware NSX, Illumio, Guardicore, or Cisco ACI ## Overview Microsegmentation divides a network into granular security zones, enforcing least-privilege access between workloads at the application layer rather than relying on traditional VLAN-based segmentation. In a zero trust architecture, microsegmentation eliminates implicit trust between workloads within the same network segment, preventing lateral movement even after an attacker gains initial access. This skill covers designing microsegmentation policies using workload identity, implementing host-based and network-based enforcement, and validating segmentation effectiveness with tools like Illumio Core and VMware NSX. ## When to Use - When deploying or configuring configuring microsegmentation for zero trust 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 ## Prerequisites - Familiarity with zero trust architecture concepts and tools - Access to a test or lab environment for safe execution - Python 3.8+ with required dependencies installed - Appropriate authorization for any testing activit...
