Network Segmentation & Firewall Engineering — The Segmentation Board

A hands-on mid-level course that carves a flat network into defensible zones. Work the segmentation board - eight domains: Zones & Design, Firewalls, Rule Hygiene, Micro-segmentation, East-West Control, Egress Filtering, Remote & VPN, and Monitoring - designing trust zones, least-access firewall rules, and lateral-movement containment with real rule and flow work. Strictly defensive. Four hands-on activities in every lesson.

What you'll learn

• Design trust zones and a segmentation strategy that fits the risk.
• Write least-access firewall rules and keep the rule base clean.
• Contain lateral movement with micro-segmentation and east-west control.
• Filter egress, secure remote access, and monitor the flows.
