This paper presents the main results of the experiments conducted using the MMT-IoT security analysis solution run on a IoT Fed4Fire+ platform (Virtual Wall - w.iLab proposed by IMEC, Belgium). MMT is a monitoring framework developed by Montimage, and MMT-IoT is the tool that allows monitoring and analysing the security and performance of IoT networks. The results obtained concern two principal advancements. First, the adaptations made to deploy MMT-IoT on the IoT platform in order to run the tool on the platform’s IoT devices. Second, the deployment of the software allowed us to run preliminary tests on the selected platform for performing initial validation and scalability tests on this real environment. To this end, Montimage defined and implemented three test scenarios related to security and scalability with 1 or more clients. These results will be used to prepare a new experimentation phase involving also another Fed4Fire+ platform (LOG-a-TEC proposed by IJS, Slovenia).
