Engaging Stakeholders in Security Design: An Assumption-Driven Approach.

Abstract

System stakeholders fail to engage with security until comparatively late in the design and development process. User Experience artefacts like personas and scenarios create this engagement, but creating and contextualising them is difficult without real-world, empirical data; such data cannot be easily elicited from disengaged stakeholders. This paper presents an approach for engaging stakeholders in the elicitation and specification of security requirements at a late-stage of a system's design; this approach relies on assumption-based personas and scenarios, which are aligned with security and requirements analysis activities. We demonstrate this approach by describing how it was used to elicit security requirements for a medical research portal.
