Abstract
The increased interconnectivity and complexity of Supervisory Control and Data Acquisition (SCADA) systems in power system networks has exposed the systems to a multitude of potential vulnerabilities. In this paper we present a novel approach for a next generation SCADA-specific Intrusion Detection System (IDS). The proposed system analyses multiple attributes in order to provide a comprehensive solution able to mitigate varied cyber attack threats. The multi-attribute IDS comprises a heterogeneous whitelist and behaviour-based concept in order to make SCADA cyber systems more secure. This paper also proposes a multilayer cyber-security framework based on IDS for protecting SCADA cyber-security in Smart Grids without compromising the availability of normal data.
