Eye Tracking Metrics for Insider Threat Detection in a Simulated Work Environment

Insider Threats (ITs) are hard to identify because of their knowledge of the organization and motivation to avoid detection. One approach to detecting ITs utilizes Active Indicators (AI), stimuli that elicit a characteristic response from the insider. The present research implemented this approach within a simulation of financial investigative work. A sequence of AIs associated with accessing a locked file was introduced into an ongoing workflow. Participants allocated to an insider role accessed the file illicitly. Eye tracking metrics were used to differentiate insiders and control participants performing legitimate role. Data suggested that ITs may show responses suggestive of strategic concealment of interest and emotional stress. Such findings may provide the basis for a cognitive engineering approach to IT detection.
