jump-server▌

This skill covers implementing secure remote access to OT/ICS environments for operators, engineers, and vendors while preventing unauthorized access that could compromise industrial operations. It addresses jump server architecture, multi-factor authentication, session recording, privileged access management, vendor remote access controls, and compliance with IEC 62443 and NERC CIP-005 remote access requirements.

Implement secure conduit architecture for OT remote access following IEC 62443 zones and conduits model, deploying jump servers, MFA-enabled gateways, session recording, and approval-based workflows to control vendor and engineer access to industrial control systems without exposing OT networks directly.
