TL;DR: Complexity-based Analysis for Anomaly Detection in Industrial Control Systems

Abstract: Industrial Control Systems (ICS) are important to critical infrastructure and are increasingly vulnerable to cyber threats due to their growing interconnectivity and complexity. The paper provides a complexity-based framework of feature evaluation in ICS cybersecurity based on the Secure Water Treatment (SWaT) datasets. The integrated framework measures the complexity of datasets by incorporating a number of complexity measures (feature-based, neighborhood-based, linearity-based and topological) into a single aggregative complexity score that depicts the complexity of a dataset. The Normalizing method is then used to remove the scale bias to ensure that the measures can be compared adequately. This principled dimensionality methodology also increases the interpretability of systems.
