Abstract

In this paper, we approach the problem of modeling the human component in technical systems with a view on the difference between the use of model and theory in sociology and computer science. One aim of this essay is to show that building of theories and models for sociology can be compared to and implemented in Higher Order Logic. We validate this working hypothesis by revisiting Weber's understanding explanation. We review Higher Order Logic (HOL) as a foundation for computer science and summarize its use of theories relating it to the sociological process of logical explanation. As a case study on modeling human behaviour, we present the modeling and analysis of insider threats as a Higher Order Logic theory in Isabelle/HOL. We show how each of the three step process of sociological explanation can be seen in our modeling of insider's state, its context within an organisation and the effects on security as outcomes of a theorem proving analysis.
