Abstract

The insider threat is a major concern for organizations. Open markets, technological advances, and the evolving definition of employee have exacerbated the insider threat. Insider threat research efforts are focusing on both prevention and detection techniques. However, recent security violation trends highlight the damage insider attacks cause organizations and illuminate why organizations and researchers must develop new approaches to this challenge. Although fruitful research is being conducted and new technologies are being applied to the insider threat problem, companies remain susceptible to the costly damage generated by insider threat actions. This research explored how visualization tools may be useful in highlighting patterns or relationships in insider attack case data and sought to determine if visualization software can assist in generating hypotheses for future insider threat research. The research analyzes cases of insider attack crimes committed during the period of 1998 to 2004 with an information visualization tool, IN-SPIRE. The results provide some evidence that visualization tools are useful in both finding patterns and generating hypotheses. By identifying new knowledge from insider threat cases, current insider threat models may be refined and other potential solutions may be discovered.
