ICS Advisory founder Dan Ricci explains why a list of operational technology (OT) assets is not an asset inventory. Asset inventories must be organized, updated, and physically validated. Only then can this facet of asset management support enterprise-wide risk management and cyber-physical systems protection programs.

From Inventory to Insight: Turning OT Visibility into Concrete Risk Reduction

Dan Ricci
AJ Eserjose, Regional Director for Operational Technology Information Sharing and Analysis Center (OT-ISAC), writes about how the information shared among members of a hub such as OT-ISAC creates a predictive resilience.  Attack, threat, and risk signals are aggregated from contributions made by different members into comprehensive intelligence that improves overall cyber and operational resilience.

How Collective Intelligence Enhances Predictive Resilience

AJ Eserjose
OT has a cybersecurity skills gap. Leading organizations, however, are responding by building cross-functional IT/OT security teams, investing in OT-specific training, creating hybrid cybersecurity roles, and leveraging managed OT security services to bridge immediate gaps. They are also prioritizing asset visibility, documentation, and standardized processes to reduce reliance on tribal knowledge.
