RT journal article T1 An automatic unsupervised complex event processing rules generation architecture for real-time IoT attacks detection A1 Roldán Gómez, José A1 Martínez del Rincón, Jesús A1 Boubeta Puig, Juan A1 Martínez, José Luis A2 Ingeniería Informática K1 Attack detection K1 Complex event processing K1 Cybersecurity K1 Internet of things K1 Machine learning AB In recent years, the Internet of Things (IoT) has grown rapidly, as has the number of attacks against it. Certain limitations of the paradigm, such as reduced processing capacity and limited main and secondary memory, make it necessary to develop new methods for detecting attacks in real time as it is difficulty to adapt as has the techniques used in other paradigms. In this paper, we propose an architecture capable of generating complex event processing (CEP) rules for real-time attack detection in an automatic and completely unsupervised manner. To this end, CEP technology, which makes it possible to analyze and correlate a large amount of data in real time and can be deployed in IoT environments, is integrated with principal component analysis (PCA), Gaussian mixture models (GMM) and the Mahalanobis distance. This architecture has been tested in two different experiments that simulate real attack scenarios in an IoT network. The results show that the rules generated achieved an F1 score of.9890 in detecting six different IoT attacks in real time.
