Abstract

Higher Education Institutions operate in ecosystems comprising multiple stakeholders to connect the most important social groups. The recent increase in cyber-attacks have had a crippling effect on Higher Education Institutions (HEIs) generating renewed calls for collaborative efforts through sharing Cyber Threat Intelligence (CTI) to generate timely, actionable insights for institutions. In fact, the higher education system is one of complex adaptive systems, where cyber resilience can be supported by social relations that encourages information sharing, cooperation and connectivity among central nodes of the system. Even though researchers have already investigated the cybersecurity collaborative work practices, very little research has emphasised the role of social capital among organisations in the cybercommunity . To this end, this work aims to explore to what extent their social capital affects their actions to propose a model that can optimise their cyber resilience through the social resources embedded in their structure. We collected relational data ( e.g. collaboration, advice, trust, best practices networks) and employed QAP correlations to reveal the extent to which interactions between and among networks reflect underlying dependencies and how networks are systematically aligned. Our preliminary results show that organizations are not consistently central across all the networks layers and reciprocity across different networks layers is low. These results provide empirical evidence on how social capital that operates through networks propagates throughout cybercommunities.
