Supervisory Control and Data Acquisition (SCADA) systems monitor and control infrastructures and industrial processes such as smart grid power and water distribution systems. Recently, such systems have been attacked, and traditional security solutions have failed to provide an appropriate level of protection. Therefore, it is important to develop security(More)
Supervisory Control and Data Acquisition (SCADA) systems are a salient part of the control and monitoring of critical infrastructures such as electricity generation, distribution, water treatment and distribution, and gas and oil production. Recently, such systems have increased their connectivity by using public networks and standard protocols (e.g.(More)
In this paper, a novel k-NN approach based on Various-Widths Clustering, named kNNVWC, is proposed to efficiently find k-NNs for a query object from a given data set. kNNVWC does clustering using various widths, where a data set is clustered with a global width first and each produced cluster that meets the predefined criteria is recursively clustered with(More)
Supervisory control and data acquisition (SCADA) systems have become a salient part in controlling critical infrastructures, such as power plants, energy grids, and water distribution systems. In the past decades, these systems were isolated and use proprietary software, operating systems, and protocols. In recent years, SCADA systems have been interfaced(More)
The traffic classification is the foundation for many network activities, such as Quality of Service (QoS), security monitoring, Lawful Interception and Intrusion Detection Systems (IDS). A recent statistics-based approach to address the unsatisfactory results of traditional port-based and payload-based approaches has attracted attention. However, the(More)
