    Example session with this skill installed

    Assess the security of our distributed control system human-machine interface environment. We have architecture documentation, a hardening checklist completed by the engineering team, and firewall rule exports for the control network boundary. The assessment is for audit readiness purposes. Key concerns are remote access configuration and privileged account management.

    • Read your context and instructions
    • Compiled the industrial-security-zones-designer
    • Generated the document

    The skill produces a structured assessment report covering: assessment scope and authorisation basis, system and environment overview, domain-by-domain findings register across authentication, remote access, interface configuration, network segmentation, logging, and hardening domains with evidence basis and severity for each finding, an evidence gap register identifying items not covered by the supplied documentation, a risk summary with operational impact statements, a prioritised remediation plan with owner placeholders, operational safety and availability notes, and an appendix with assumptions and evidence inventory. Confirmed findings are clearly separated from evidence gaps, and no vulnerabilities, configurations, or compliance conclusions are generated without evidential support.

    About this skill

    What it does

    The Industrial Security Zones Designer is a specialized technical skill for architecting and auditing Operational Technology (OT) and Industrial Control System (ICS) network segmentation. It follows the ISA/IEC 62443 standard to help engineers and security professionals define security zones, manage conduits, and map assets based on Purdue Model levels, criticality, and functional requirements.

    Problem it Solves

    Industrial networks often suffer from "flat" architectures or improper IT/OT convergence, leading to significant security risks. Manually designing zones that respect safety-critical constraints, process integrity, and complex traffic flows is error-prone. This skill automates the logic of zone and conduit design while ensuring compliance with global industrial standards.

    Supported Frameworks and Tools

    • Standard Frameworks: Primarily IEC 62443, Purdue Enterprise Reference Architecture (PERA), and NIST SP 800-82.
    • Vendor Neutrality: Works with data from any firewall (Fortinet, Cisco, Palo Alto), asset inventory tool (Nozomi, Claroty, Dragos), or network monitoring system.
    • Output Formats: Generates zone/conduit registers, firewall flow allowlists, and remediation roadmaps.

    Why use this skill?

    Unlike generic AI prompting, this skill enforces strict industrial safety constraints and architectural logic. It prevents the common AI pitfall of "hallucinating" network paths or proposing dangerous destructive testing. It ensures that every conduit has a business justification, specific directionality, and identified security controls.
