Hardening Edge Infrastructure: pfSense & VLAN Segmentation

Configuring a secure lab environment for offensive research.

Infrastructure Layout

To maintain OPSEC and isolate exploit testing, I’ve implemented a multi-VLAN structure.

  • VLAN 10 (Management): Isolated for primary workstations.
  • VLAN 20 (Lab): Where the “vulnerable” targets live.
  • VLAN 30 (Red): Dedicated for C2 traffic and egress testing.

Firewall Rules

Rules are configured on a Deny-by-Default basis. Only specific ports are mirrored to the IDS for traffic analysis.
