Understanding and Mitigating Insider Threats in Operational Technology (OT) Systems

This report summarizes insider threats to OT/IT environments, outlining the main categories (human error, disgruntled employees, externally motivated), typical impacts (financial loss, safety risks, privacy breaches), common psycho-social indicators, and recommended mitigations such as increased visibility, risk assessments, security culture, and separation of duties. It highlights prevalence and containment statistics and provides guidance rather than describing a specific incident.
