SUMMARY

Threats arising from within NC3 systems can have particularly devastating consequences. Drawing on knowledge of insider threats from the nuclear enterprise and other fields, this paper examines fundamental concepts of insider threats and provides an overview of the extent and significance of insider threats. It outlines some current models of insider threat, including behavioral indicators, and current efforts at ensuring personnel reliability. Finally, it focuses on the vulnerabilities of the nuclear enterprise to insider threat in the current environment and discusses some challenges to addressing the insider threat problem on a global scale.

In this essay, Dr. Ronald Schouten concludes: “The risk of insider threats is real, global, and likely to increase along with world and domestic tensions and socio-cultural changes. Combatting that risk will require a comprehensive approach that recognizes cultural and societal differences, as well as awareness that policies, procedures, and technical solutions are dependent upon acceptance of the risk and the full engagement of the nuclear work-force.”
