EUSTO’s proposal originates from the real-world necessity to provide comprehensive and consolidated protection to surface transportation protection networks. In accordance with EU regulations, the responsibility for implementing protection programs lays with the CI operator and national authorities, and ongoing efforts for the identification and designation of major European CI in the transportation sector have been lacking progress in recent years. This proposal originates from this drawback in the implementation of the CIPS directive in the EU and aspires to make a small but vital contribution to its implementation.
