Summary
In today’s world, the demand for process data has skyrocketed, alongside a significant increase in cybersecurity threats. Establishing secure data connections between operational technology (OT) and cloud systems is paramount, ideally achieving zero exposure to outside threats. Two main technologies for achieving this level of security are MQTT and tunnel/mirroring, with tunnel/mirroring offering some advantages over MQTT.
Key practices such as closing inbound connections and implementing network segmentation through a demilitarized zone (DMZ) are outlined. While MQTT offers some benefits for outbound connections, tunnel/mirroring technology overcomes several of MQTT’s limitations, ensuring reliable data transfer and consistency. Security protocols, including SSL encryption and user authentication, are essential for safeguarding connections.
