ASL Roma 1’s Healthcare Operational Protection & Excellence (HOPE) cybersecurity and risk governance framework is re-organizing the way it recognizes assets via their relationships. According to CISO Stefano Scaramuzzino and Deloitte’s Fabio Battelli, this is a better reflection of how healthcare organizations view events and mitigate exposures, based upon their dependencies and strategic value.

Operational resilience must evolve as artificial intelligence becomes a prominent tool in the protection of operational technology (OT) and cyber-physical systems (CPS). Defenders may use AI to correlate operational signals at machine speed to make more context-informed judgments about the intent behind changes to a facility.

Project Glasswing and the Claude Mythos Preview have caused an upheaval related to vulnerability discovery and exploit development. On Nexus, former NSA Director Adm. Michael S. Rogers introduces some nuance to the discussion. The nuance that isn’t being articulated enough, he says, is that Project Glasswing is largely a defensive effort that does more to level the playing field between threat actors and defenders than we may realize.

Providence CISO Mike Ratliff writes about his organization's adoption of artificial intelligence. While AI is making rapid inroads in terms of reducing the time around low-impact, high-frequency tasks, there's still caution around deep deployments on systems that affect patient care directly. Providence's test-validate-scale model reflects the realities of healthcare, where changes must be introduced carefully to avoid unintended consequences.

Former Pfizer Global Head of Automation Engineering James LaBonty writes about how to develop an AI-powered cybersecurity strategy to protect cyber-physical systems (CPS) in manufacturing environments. An AI-powered CPS security strategy in manufacturing should establish operational resilience as its prime mission statement. That means ensuring that uptime of manufacturing assets is paramount. It also means strategizing about how to handle the growing influx of vulnerability disclosures driven by frontier AI models
