| contents | Traditional two-dimensional risk matrices (heatmaps) are widely used to model and visualize likelihood and impact relationships, but they face fundamental methodological limitations when applied to complex infrastructures. In particular, regulatory frameworks such as NIS2 and DORA call for more context-sensitive and system-oriented risk analysis. We argue that incorporating contextual dimensions into heatmaps enhances their analytical value. As a first step towards our Hagenberg Risk Management Process for complex infrastructures and systems, this paper introduces a multidimensional (ND) polar heatmap as a formal model that explicitly integrates additional context dimensions and subsumes classical two-dimensional models as a special case. |
