OT Cybersecurity Insights from the Frontlines – 2022 Year In Review Webinar Recap
Summary: Dragos reported that 80 percent of its 2022 service engagements found limited to no visibility inside ICS/OT environments, and 50 percent identified network segmentation issues, often direct connections between OT segments and IT or business networks. External connections to OT environments fell 17 percent to 53 percent from 70 percent, while shared credentials rose 54 percent, with Dragos citing reused local administrator passwords and shared logins as factors easing lateral movement.
Bottom line: Shared credentials rose 54 percent in a year when most engagements already lacked visibility inside OT, so the reuse of local administrator passwords gives an intruder who lands on the IT side a short path into the networks that run physical processes.
