Understanding and Mitigating Insider Threats in Operational Technology (OT) Systems
Summary: Dragos cites Ponemon Institute survey data showing insider threat incidents rose 47% from 2018 to 2020 and a further 44% in the two years after, with most affected companies experiencing more than 30 attacks per year. The post groups insider threats into human error, disgruntled employees, and externally motivated actors, noting that human error accounted for 56% of surveyed incidents at an average cost of $6.6 million per year and that insider incidents take an average of 85 days to contain.
Why it matters: Only 12% of insider incidents are contained in under 30 days, and in OT environments the people involved hold emergency override access that can affect physical safety and public health.
