Abstract [en]

This article discusses the design and specifications of a Socio-Technical Security Information and Event Management System (ST-SIEM). This newly-developed artifact addresses an important limitation identified in today incident response practice—the lack of sufficient context in actionable security information disseminated to constituent organizations. ST-SIEM tackles this limitation by considering the socio-technical aspect of information systems security. This concept is achieved by correlating the technical metrics of security warnings (which are generic in nature, and the sources of which are sometimes unknown) with predefined social security metrics (used for modeling the security culture of constituent organizations). ST-SIEM, accordingly, adapts the risk factor of the triggered security warning based on each constituent organization security culture. Moreover, the artifact features several socio-technical taxonomies with an impact factor to support organizations in classifying, reporting, and escalating actionable security information. The overall project uses design science research as a framework to develop the artifact.

Abstract [en]

This thesis examines the cybersecurity incident response problem using a socio-technical approach. The motivation of this work is the need to bridge the knowledge and practise gap that exists because of the increasing complexity of cybersecurity threats and our limited capability of applying cybersecurity controls necessary to adequately respond to these threats. Throughout this thesis, knowledge from Systems Theory, Soft Systems Methodology and Socio-Technical Systems is applied to examine and document the socio-technical properties of cybersecurity incident response process. The holistic modelling of cybersecurity incident response process developed concepts and methods tested to improve the socio-technical security controls and minimise the existing gap in security controls.

The scientific enquiry of this thesis is based on pragmatism as the underpinning research philosophy.  The thesis uses a design science research approach and embeds multiple research methods to develop five artefacts (concept, model, method, framework and instantiation) outlined in nine peer-reviewed publications. The instantiated artefact embraces the knowledge developed during this research to provide a prototype for a socio-technical security information and event management system (ST-SIEM) integrated with an open source SIEM tool. The artefact relevance was validated through a panel of cybersecurity experts using a Delphi method. The Delphi method indicated the artefact can improve the efficacy of handling cybersecurity incidents.
