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…
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…
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…
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…
