Visualising Personas as Goal Models to Find Security Tensions.

Abstract

This paper presents a tool-supported approach for visualising personas as social goal models, which can subsequently be used to identify security tensions. We devised an approach for partially automating the construction of social goal models from personas. We provide two examples of how this approach can be used to identify previously hidden implicit vulnerabilities, and validate ethical hazards faced by penetration testers and safeguards that address them. Visualising personas as goal models makes it easier for stakeholders to see implications of their goals being satisfied or denied, and designers to incorporate the creation and analysis of such models into the broader RE tool-chain. Our approach can be adopted with minimal changes to existing User Experience (UX) and goal modelling approaches and Security Requirements Engineering tools.
