*4.7. Security Monitoring Capabilities*

One of the papers identified dealt with improving security monitoring capabilities for water distribution systems. In [118], researchers propose sonification, data in audio, to help system operators avoid cognitive overloading with visual information to raise alarms for cyber-attacks on water distribution systems. Motivated by prior work on sonification, designed to improve monitoring capabilities, researchers designed a sonification system to reduce the overload of human operators faced with visual channels, to support better decision-making for a water facility by sonifying the outputs of an anomaly detection model. Current anomaly detection models are represented as visual diagrams showing anomalous data points at a given time and often an alarm is raised when a threshold is reached.
