segmentation

Validating network segmentation against NIST 800-207 involves mapping trust boundaries and enforcement points to identify implicit trust or bypass paths. A structured review checks zone mappings and east-west controls to ensure Zero Trust policy enforcement across your architecture.

Assessing micro-segmentation involves reviewing intra-zone controls and workload isolation to verify readiness for policy enforcement. An east-west control check evaluates lateral movement paths within VPCs, VLANs, or Kubernetes network policies to pinpoint segmentation gaps.

Checking DMZ architecture and PCI DSS segmentation involves validating CDE boundary enforcement against PCI DSS v4.0 Requirement 1.3 expectations. A structured review verifies trust boundaries and policy enforcement points to prevent bypass paths into the cardholder data environment.

Reviewing Kubernetes network policies for lateral movement vulnerabilities is supported by evaluating workload isolation and intra-zone controls. The assessment maps micro-segmentation boundaries to identify permissive rules and verify east-west traffic enforcement.

A structured network segmentation review is needed after architecture changes, during design reviews of VLAN or VPC layouts, or for post-incident scoping of suspected lateral movement. It evaluates Zero Trust compliance and produces a prioritized remediation plan.
