Secure SCADA Communication Network for Detecting and Preventing Cyber-Attacks on Power Systems

This paper presents a scaled model for supervisory control and data acquisition (SCADA) communication network, which monitors and controls power distribution in residential areas. We recommend to integrate advanced communication technologies into current SCADA system to improve its performance in monitoring and controlling the operations of the power systems. This paper further proposes to use ad hoc wireless sensor networks in the residential areas as a part of SCADA communication in power distribution network. Moreover, a trust-based intrusion detection and prevention (IDP) technology built on monitoring, detecting, and rehabilitation (MDR) approach is applied to the proposed network for cyber security analysis. To verify the performance of the proposed SCADA communication network using MDR, simulation is carried out for three different cases and results demonstrate that the proposed MDR approach helps in detecting and preventing the malicious nodes in the network effectively.
