Unlocking SCADA: Securely Moving OT Telemetry to Enterprise IT

说明与用途

通过专用中间件、一向数据二极管和集成中心，将 SCADA 远程监控数据安全地集成到企业 IT 系统，实现实时数据流动，提升产能规划和预测性维护，同时保持 OT 网络的隔离与安全。

问题

Legacy SCADA systems use outdated protocols (DNP3, Modbus, OPC DA) that cannot directly feed real‑time telemetry into modern IT systems, forcing manual CSV exports or fragile scripts that expose security risks.

结果

Real‑time OT telemetry is securely streamed to enterprise IT, enabling accurate capacity management, predictive maintenance, and automated compliance reporting while maintaining strict OT isolation.

工作流

• 1. Deploy an edge gateway on the OT network to ingest native protocols (DNP3, Modbus, OPC DA).
• 2. Configure the gateway to filter and buffer telemetry, sending only business‑relevant data.
• 3. Place a one‑way data diode between OT and IT to enforce unidirectional flow.
• 4. Route data through a DMZ proxy to isolate OT devices from IT servers.
• 5. In the IT side, use an integration hub to transform data into JSON/XML and map it to ERP/CRM schemas.
• 6. Expose the transformed data via secure, documented APIs to business applications.

证据

Right now, many US utility and manufacturing companies rely on what I call "human routers." They have people manually exporting CSV files from an air‑gapped terminal, walking them across a room on a USB drive, and uploading them into a corporate database.

The "aha" moment for most organizations is realizing they need a strict, one‑way data diode.

Bridging this technical divide safely requires utility automation solutions built with deep SCADA integration expertise that natively respect network segmentation.
