ABSTRACT
This chapter explores the nature of trust and its relationship with insider risk. It considers the characteristics that make people trustworthy, and ways of judging whether a person is telling the truth. Trust is the universal currency of insider risk and personnel security. It is a psychological state comprising the intention to accept vulnerability based upon positive expectations of the intentions or behaviour of another. To be judged trustworthy, a person or other entity should possess four attributes: benign intentions, integrity, competence, and consistency. Trust has pervasive benefits that extend beyond the mitigation of insider risk. Most people are poor at judging whether a person is telling the truth, and we are all prone to self-deception. Issues of trust and trustworthiness are becoming increasingly important in the context of intelligent machines.
