Securing the Shop Floor: PLC-to-Cloud Industrial Data Safety

01. Strategic Manufacturing Context

Modern factories risk network exposure when connecting legacy PLCs or CNC machines to the cloud. This research paper addresses the critical need for isolated data bridges in Industrial IoT implementations.

02. Technical Architecture & SCADA Integration

Implementing hardware-level firewalls and MQTT with TLS 1.3 encryption ensures that machine telemetry is transmitted securely without exposing the internal factory control network to the public internet.

SYS_LOG: Machine Monitoring enabled // Protocols: Modbus/TCP, MTConnect, OPC-UA // Cloud SCADA: Active

03. IIoT Digitization Implementation

The WhereFy security layer acts as a 'One-Way Data Diode,' allowing machine monitoring data to exit the shop floor while preventing any unauthorized external commands from reaching the CNC controllers or PLCs.

Industrial ROI & Impact

A secure, zero-trust framework for industrial digitization that satisfies global IT-OT security standards while maintaining 100% data visibility for production managers and stakeholders.
