MQTT and CoAP: Security and Privacy Issues in IoT and IIoT Communication Protocols

Machine-to-machine (M2M) communication protocols, which enable machines to “talk” with one another so that commands are communicated and data is transmitted, are indispensable to applications and systems that make use of the internet of things (IoT) and the industrial internet of things (IIoT).Message Queuing Telemetry Transport (MQTT) is a communication protocol widely used in both IoT and IIoT deployments.

Impact to large-scale implementations: Smart factories and smart cities

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 […]

Machine-to-Machine (M2M) Technology Design Issues and Implementation Vulnerabilities

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 […]

Creating a Scalable MQTT Environment

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 […]
