Another significant move that will help IT/OT integration is the planned integration of the management console for Cisco’s Catalyst and Meraki networks. That combination will allow IT and OT teams to see the same dashboard for industrial OT and IT enterprise/campus networks. Cyber Vision will feeds into the dashboard along with other Cisco management offerings such as ThousandEyes, which gives customers a shared inventory of assets, traffic flows and security.
“What we are focusing on is helping our customers have the secure networking foundation and architecture that lets IT teams and operational teams kind of have one fabric, one architecture, that goes from the carpeted spaces all the way to the far reaches of their OT network,” Butaney said.
For too long, OT security has been thought of as a specific cybersecurity practice to be managed with point products, Butaney wrote in a blog post earlier this year: “As industrial organizations start deploying these, they realize that they need most of their IT cybersecurity tools to properly protect the OT environment, and that they also need to detect and remediate threats across domains.”
“Protecting industrial operations means profiling and monitoring tens of thousands of industrial assets, often installed in hard-to-reach locations. The traditional approach consisting of deploying dedicated appliances for OT visibility, threat detection, network segmentation, and secure remote access is proving too complex to deploy, too costly to scale, and in some cases just impractical,” Butaney wrote.
A recent report from IDC went even further, stating that 50% of OT assets are more than 10 years old, and their security posture needs to be assessed.
“Most OT networks remain unsegmented, leaving critical assets exposed and increasing the likelihood of lateral movement during attacks. Adaptive security policies and real-time segmentation are common in IT. These solutions can help minimize risks in OT without disrupting operations if they are integrated with OT visibility products,” wrote IDC’s Romain Fouchereau, senior research manager, European security.
