# 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.
