Designs and implements IEC 62443-3-2 security zones and conduits for OT networks, covering risk-based partitioning, SL-T assignment, industrial firewall microsegmentation, and validation through traffic analysis and penetration testing aligned with the Purdue Reference Model.

Applies the Purdue Enterprise Reference Architecture to ICS/SCADA networks, mapping assets to hierarchical security zones, defining firewall/VLAN rules, and enforcing OT-to-IT DMZ controls so IEC 62443 requirements and defense-in-depth strategies are met.
