The Intersection of Resilience & Regulation
New York Ordered Utilities to Inventory Their AI. What Happens When It Changes?
New York has ordered 12 utilities to inventory every artificial intelligence (AI) use case by November 16, and Arizona is collecting similar information through a docket.

Its broad definitions suggest applicability to both IT and OT systems, signaling a significant expansion in cybersecurity oversight for municipalities and public authorities.
