USACM Energy & Earth Systems TTA Seminar - Shamina Shahrin Hossain-McKenzie

June 23, 2026 Shamina Shahrin Hossain-McKenzie, Sandia National Laboratories griDNA: AI-powered Distributed Anomaly Detection In this talk, the griDNA cyber-physical security technology will be presented as well as field testing results at a utility photovoltaic site. griDNA is designed to protect distributed critical infrastructure systems such as power grids, pipelines, and transportation networks against disruptions caused by cyber-attacks or system failures. The technology continuously gathers and analyzes system data using autoencoder neural networks to fuse together cyber-physical data streams. For detected events, griDNA alerts operators and defenders with early detection of cyber, physical, or combined cyber-physical abnormal behavior, whether it stems from inadvertent equipment failures or malicious cyber attacks.
