Understanding Security Patterns for Socio-technical Systems via Responsibility Modelling

Abstract

Increasingly, security requirements are being viewed as a social construct derived from the culture and society within which the requirement is said to exist. A socio-technical system can be modelled as a series of inter-related, and interacting patterns of behaviour. Within a socio-technical system a security requirements can be derived from the analysis and interaction of the pattern. To capture and understand these requirements/patterns we need to make use of a formal reasoning system that supports a rigorous deductive process. In this paper we will develop a formal model of a socio -- technical systems pattern using a Kripke Semantic model. Then, via the application of Kripke Semantics to the modelling of responsibilities and how they are created/fulfilled within a socio -- context, we will derive a set of security requirements/patterns.
