Researchers have developed PhaseNet++, a novel approach for detecting anomalies in industrial control systems (ICS) by leveraging phase information from time-frequency transformations. Unlike previous methods that focus solely on amplitude, PhaseNet++ utilizes both magnitude and phase spectra from the Short-Time Fourier Transform. The system incorporates a Phase Coherence Index to guide a graph attention network and a Transformer encoder to capture system-wide structures, achieving high performance on the Secure Water Treatment (SWaT) benchmark.
