摘要：Insider threats are both social and technological phenomena, and g roup dynamics can provide important indicators to help counter insider threats. This paper discusses an experimental study that simulates insider betrayal in a n online collaborative environment. This study uses the framework of trustw orthiness attribution, wherein the autho rs examine the trustworthiness of a focal individual wh ose role was in leadership with authority within a trusted team arrangement . Specifically, t he authors adopted a finite - state machine (FSM) approach to analyzing pattern s of a group's emotional states in order to understand how members collectively distinguish insider betrayal through computer - mediated interactions , social connectivity and coordination. Moreover, these conditions help us understand how human observation s of betraya l can be leverage d to provide early warnings to betrayal . Of the four simulated case studies conducted, tw o provide baseline measures , and the other two provide treatment measures . Findings indicate that signs of potential betrayal can be collectively identified by team members through text and behavioral patterns – to uncover social intent that is not explicitly stated
