An approach to assess criticality of elements in the process of information infrastructure protection

In this paper the new approach to assessment an importance/criticality of elements within the critical information infrastructure is presented. The proposed method is based on the identification of critical routes within the network, and the recognition of the most important nodes without using centrality measures and simulation techniques. The elements and their dependencies within the information infrastructure are transformed into a relational topological graph. The elements are presented as the nodes, and the relations between them as the edges of the graph.
