Does this skill support specific industrial protocols?

Yes, it includes Deep Packet Inspection (DPI) profiles for common OT protocols including Modbus, OPC UA, S7Comm, ENIP, and DNP3.

How does it handle the transition from a flat network?

It provides a phased 8-week migration plan that prioritizes high-risk areas like the OT-DMZ and SIS isolation to minimize operational downtime.

Is this skill suitable for pure IT environments?

While the logic of segmentation is universal, this skill is specifically optimized for OT/ICS environments and the Purdue Enterprise Reference Architecture.

Are hardware-specific configurations included?

The skill provides configuration snippets for industrial-grade hardware such as Cisco IE-4000/5000 series switches and OT-aware firewalls.

Security & Testing

Implements secure network architectures for Operational Technology (OT) and Industrial Control Systems (ICS) using the Purdue Model.

This skill provides comprehensive guidance for designing and implementing network segmentation within OT environments to protect critical infrastructure. It leverages the Purdue Model-based strategy to separate safety instrumented systems (SIS) from basic control systems and corporate IT, ensuring compliance with IEC 62443 standards. By utilizing VLANs, industrial firewalls, and deep packet inspection (DPI), it helps organizations transition from flat networks to resilient, segmented architectures without disrupting industrial operations.
