The importance of automated intrusion detection systems, not only in network infrastructures, but also in critical and industrial infrastructures is becoming more evident with the significant increase of cyber-attacks targeting such infrastructures. The most recent research initiatives in this field focus on unsupervised learning methods, due to a constant lack of labelled datasets of a good quality. This paper proposes an enhanced autoencoder based anomaly detection approach for water distribution cyber-attack detection. The proposed approach contains a pipeline of methods, including feature engineering as a pre-processing step, anomaly estimation based on autoencoder, and scores smoothing as a post-processing step. The obtained results are very promising compared to existing approaches.
