Abstract
Water distribution systems are undergoing a process of intensive digitalization, adopting networked devices for monitoring and control. While this transition improves efficiency and reliability, these infrastructures are increasingly exposed to cyber-attacks. Cyber-attacks engender anomalous system behaviors which can be detected by data-driven algorithms monitoring sensors readings to disclose the presence of potential threats. At the same time, the use of sonification in real time process monitoring has grown in importance as a valid alternative to avoid information overload and allowing peripheral monitoring. Our project aims to design a sonification system allowing human operators to take better decisions on anomalous behavior while occupied in other (mainly visual) tasks. Using a state-of-the-art detection algorithm and data sets from the Battle of the Attack Detection Algorithms, a series of sonification prototypes were designed and tested in the real world. This paper illustrates the design process and the experimental data collected, as well results and plans for future steps.
