Analysis of IoT Security Risks based on the exposure of the MQTT Protocol

Due to the tremendous growth of Internet Things (IoT) applications - e.g. smart homes, grids, factories – and emerging integration into industrial systems, cyber threat landscape for IoT IIoT is rapidly evolving. Security by Design principles are still widely neglected in design devices protocols. For consumer IoT, privacy applicant can be compromised when inappropriately secured. With regard Industrial usage insecure protocols such as MQTT have a severe impact on environment failure or impairment production systems. We evaluate prevalence exposed related protocol means search engine Shodan. The approach, results our analysis summarized this paper.
