Skill UI

This skill provides a comprehensive guide to implementing secure, defense-in-depth remote access architectures for Operational Technology (OT) and Industrial Control Systems (ICS). It covers best practices such as using jump servers, implementing Multi-Factor Authentication (MFA), session recording, and adhering to standards like IEC 62443 and NERC CIP-005 for vendor and operator access.

This guide details implementing an IEC 62443 compliant conduit architecture for secure remote access into Operational Technology (OT) environments. It mandates the use of jump servers, MFA gateways, session recording, and approval workflows within a DMZ to strictly control vendor and engineer access, eliminating direct VPN connections to critical ICS assets.
