As billions of devices join industrial networks, the communication protocols that connect them become prime targets for cyberattacks. MQTT and CoAP are two of the most widely deployed messaging protocols in IoT and IIoT environments, yet each carries distinct security and privacy vulnerabilities that operations teams must understand and mitigate. In this IIoT World explainer, […]

In this article we discuss how insecure deployments and the lack of well-defined security in M2M technology can be abused to turn into unforeseen problems in critical and large-scale environments like smart factories and cities.M2M technology forms the core of IIoT systems for maintaining smart factories and building smart cities. As more of these connected […]

In our latest research paper, titled “The Fragility of Industrial IoT’s Data Backbone: Security and Privacy Issues in MQTT and CoAP Protocols” and written with Rainer Vosseler and Davide Quarta, we discussed how MQTT and CoAP are affected by design issues and implementation vulnerabilities that can allow attackers to subvert devices enabled by these two […]

MQTT, a light-weight IoT messaging protocol over TCP/IP, is designed for large-scale telemetry environments with remote locations where a small code footprint is required and/or network bandwidth is limited. It operates as a producer-consumer paradigm, where many “Publishers” (for example, sensors) send out messages to a small set of “Subscribers” (for example, client applications), which […]
