Securing the Shop Floor: PLC-to-Cloud Industrial Data Safety
01Strategic 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 and security-first architectures in Industrial IoT implementations.
02Technical Architecture & 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 public internet threats. Our approach includes certificate-based authentication for all devices.
03Implementation & Architecture
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. This zero-trust architecture ensures complete operational safety.
04Industrial ROI & Impact
A secure, zero-trust framework for industrial digitization that satisfies global IT-OT security standards (ISO 27001, NIST) while maintaining 100% data visibility for production managers and stakeholders without compromising factory operations.
