This guide details the robust process of implementing VLAN-based (802.1Q) network segmentation on managed switches. It is crucial for isolating critical zones—such as DMZ, servers, and IoT—to meet strict compliance standards (PCI-DSS, HIPAA) and significantly limiting the blast radius during a security incident by controlling lateral movement. Includes port hardening and ACL configuration.

This skill simulates advanced Layer 2 network attacks, including VLAN hopping, using techniques like switch spoofing (DTP) and 802.1Q double tagging. It is designed exclusively for authorized penetration testing environments to validate network segmentation, test trunk port hardening, and assess the risk of unauthorized VLAN access across the network infrastructure.
