Context-aware local Intrusion Detection in SCADA systems: A testbed and two showcases

This paper illustrates the use of a testbed that we have developed for context-aware local intrusion detection. This testbed is based on the co-simulation framework Mosaik and allows for the validation of local intrusion detection mechanisms at field stations in power distribution networks. For two cases, we show how this testbed assists with studying the effectiveness of two local IDS mechanisms under different kinds of attacks.
