    "body_text": "A power-grid security model can score well on prediction while still making expensive operational mistakes. A new study couples its detector with an optimization process that translates errors into cyber-physical risk costs. Learning and operational decisions communicate iteratively instead of being optimized in isolation. Tests on the Industrial Control System Cyber Attack and Sherlock datasets show improved operating costs relative to the traditional approach, according to the authors. The evidence is a dataset evaluation. It makes a concrete case for judging detection systems by the decisions their alarms cause.",
