Analysing Information Systems Security

The paper describes problems with managing information systems security, due to its complexity and broad scope. Then, a security taxonomy is presented and discussed. The taxonomy is used in conjunction with different approaches to information security analysis, including the evaluation of different cost-benefit criteria. The paper also uses the terms proactive and reactive analysis as a way of differentiating between analysis methods. Moreover, the paper presents concepts from other research areas that can be used as a basis for a proactive security analysis approach. Elements from a proactive model for quality assurance in food production (HACCP) are incorporated in the model, as is the usage of established multivariate statistical methods. The paper discusses and suggests how such a security analysis tool may look in a conceptual form.
