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.

Deploy Cisco Duo multi-factor authentication across enterprise applications, VPN, RDP, and SSH access points. This skill covers Duo integration methods, adaptive authentication policies, device trust

Implement continuous identity verification for zero trust using phishing-resistant MFA (FIDO2/WebAuthn), risk-based conditional access, and identity governance aligned with the CISA Zero Trust Maturity Model.

Add Multi-Factor Authentication to protect user accounts and require additional verification for sensitive operations.
