An Information Governance Model for Information Security Management
Abstract
The purpose of this paper is to propose an IS security governance model to enhance the security of information systems in an organisation by viewing security from a holistic perspective of encompassing information security, information assurance, audit, governance, and compliance. This is achieved through the strategic integration of appropriate frameworks, models, and concepts in information governance, IS service management, and information security. This involves analysing the relevant frameworks, models, and concepts used in the above domains, extracting the best practices for implementing them from the literature and mapping these into an integrated standard. The frameworks identified are Control Objectives for Information and related Technology (COBIT), Information Technology Infrastructure Library (ITIL), ISO 27002, Risk IT, and Payment Card Industry Data Security Standard (PCI DSS). While it is evident that each of these five frameworks serve different purpose of information systems, such as information auditing and governance, facilitating the delivery of high-quality IT services, providing a model managing an Information Security Management System, providing a risk focus, and protection of cardholder data, all of these frameworks have the common objective to secure the IS assets in an organisation. Hence, extraction of the best practices in each of these framework can provide effective security of organisational IS assets rather than adequate security.
