A new intrusion detection approach against lethal attacks in the smart grid:temporal and spatial based detections

The smart grid is the new vision of the traditional power grid, which is characterized by the integration of communication network between all its components beginning from the producers, going through the transmission and distribution units and finishing by the consumers and end users. The heterogeneity of its components imposes a sophisticated security architecture to protect the smart grid from any attack´s attempt. In this paper, we propose an architecture in which Intrusion Detection System (IDS) agents are implemented with a distributed manner to monitor the consumer side, building appliances and smart meters. Those IDSs rely on rule-based detection policy, which consists in the combination of temporal and spatial detection rules. Simulation results prove that this combination enhances attack´s detection rate and reduces false positive rate.
