M.A. Hawila and S.S. Chirayath, “Nuclear Security Risk Analysis: An Insider-Outsider Collusion Scenario”, International Journal of Nuclear Security, 2, 2 (2016).
This study analyses the vulnerability of the physical protection system (PPS) deployed at a hypothetical facility. The PPS is designed to prevent and eliminate threats to nuclear materials and facilities. The analysis considers possible outsider and insider threats. A modified adversary sequence diagram (ASD) evaluates threat pathways to test an insider-outsider collusion case. The ASD also measures the probability of adversary interruption by demonstrating the methodology for a typical nuclear facility.
