implementing-conduit-security-for-ot-remote-access

Implements secure conduit architecture for OT remote access under the IEC 62443 zones-and-conduits model, deploying jump servers, MFA gateways, session recording, and approval-based workflows for vendor and engineer access to ICS. Use when replacing direct VPN access into OT networks, securing third-party vendor access to SCADA equipment, or remediating audit findings on uncontrolled OT remote access.

# Implementing Conduit Security for OT Remote Access

## When to Use

- When replacing direct VPN connections from IT or vendors into OT control networks
- When implementing IEC 62443-compliant conduit architecture for remote access paths
- When deploying secure remote access for third-party vendor maintenance of ICS equipment
- When building approval-based access workflows for privileged OT system access
- When remediating audit findings about uncontrolled remote access to SCADA systems

**Do not use** for designing the overall Purdue Model segmentation (see implementing-purdue-model-network-segmentation), for deploying IT-only remote access solutions, or for configuring local console access to PLCs.
