How to Improve OT Network Visibility
Summary: Dragos reported that 86% of its service engagements in 2021 showed a lack of visibility across OT networks, down from 90% in 2020. The 2021 Year In Review also flagged poor security perimeters, external connections to ICS environments, and a lack of separation between IT and OT user management, with visibility described as the starting point for asset inventories, configuration and vulnerability management, rogue access point detection, and threat detection.
What's compelling: Dragos observed enterprises shutting down operations after ransomware hit their enterprise networks, out of fear the compromise would spread to OT - a fear rooted in not knowing the data flows between IT and OT or the assets that bridge them. With 86% of engagements still lacking OT network visibility, that blind spot in the attack surface remains the norm rather than the exception.
