Abstract

The management of adverse events within organisations has become a pressing issue as the perceptions of risk continue to heighten. However the basic need for developing secure information systems has remained unfulfilled. This is because the focus has been on the means of delivery of information, i.e. the technology, rather than on the various contextual factors related to information processing. The overall aim of this research is to increase understanding of the issues and concerns in the management of information systems security. The study is conducted by reviewing the analysis, design and management of computer based information in two large organisations - A British national Health Service Hospital Trust and a Borough Council. The research methodology adopts an interpretive mode of inquiry. The management of information systems security is evaluated in terms of the business environment, organisational culture, expectations and obligations of different roles, meanings of different actions and the related patterns of behaviour. Findings from the two case studies show that an inappropriate analysis, design and management of computer based information systems affects the integrity and wholeness of an organisation. As a result, the probability of occurrence of adverse events increases. In such an environment there is a strong likelihood that security measures may either be ignored or are inappropriate to the real needs of an organisation. Therefore what is needed is coherence between the computer based information systems and the business environment in which they are embedded. In conclusion, this study shows that to resolve the problem of managing information systems security, we need to understand the deep seated pragmatic aspects of an organisation. Solutions to the problem of security can be provided by interpreting the behavioural patterns of the people involved.
