Network Security Lab

Explore firewall rules, VLANs, network topology, and device hardening

Overview

Explore a simulated network of firewalls, routers, switches, and access points. Inspect open ports, review firewall rule sets, and identify devices exposing risky services to the wrong segments of the network.

Why This Lab Matters

Network security is the foundation layer that everything else sits on. Misconfigured firewalls and exposed ports are still among the most common ways attackers get an initial foothold. Understanding network architecture and segmentation is essential for any security role.

What You'll Gain

  • Learn to read firewall rules and spot risky open ports
  • Understand how device type and risk level relate to exposure
  • Practice thinking in terms of network segmentation and VLANs
  • Build a mental model of enterprise network architecture
