Abstract: Security issues in information management are increasingly moving towards the centre of corporate interests. This paper presents a multiobjective modelling approach that interactively assists IT managers in their attempts to reduce a given risk by evaluating and selecting portfolios (i.e. bundles) of security measures. The proposed multi-step procedure identifies attractive portfolio candidates and finally establishes the "best" one with respect to the decision-maker's preferences. Our model and its possible application are demonstrated by means of a numerical example based on real-world data that evaluates the risk of hacking faced by a Local Area Network in an academic environment.
