Adverse cyber incidents are some of the top risks currently facing the global community. Cybersecurity frameworks and models formulated to mitigate these risks are typically framed from the organizational perspective of governments and the private sector. Further, they are traditionally techno-centric solutions framed from a cybersecurity perspective towards prevention of risks; only recently are they incorporating resilience perspectives towards anticipation of risks and positive adaptation during adverse cyber incidents. This research makes advances on human-centric cyber resilience - from the perspective of citizens and centered on citizens’ multi-dimensional experience of adverse cyber incidents. It considers the goal of cyber resilience, from the capabilitarian perspective, as enhancing the cyber capabilities of individuals and achieving positive adaptation in the face of adverse cyber incidents. This paper presents an ontology that is formulated to formalize individuals’ cyber resilience. The paper motivates the need for such an ontology and discusses the constitutive concepts. Finally, it shows how this ontology can support the realization of cyber resilience for individual citizens.
