Securing MQTT: Best Practices for a Robust IoT Ecosystem


MQTT is a widely used protocol for connecting IIoT industrial devices, enabling efficient and real-time data exchange. However, it often gets misunderstood for security vulnerabilities, leading to misconceptions about its safety. In this paper, we will discuss essential steps to ensure MQTT security, from edge devices to cloud servers, and how to address denial of service (DoS) attacks effectively.
