The development of an information society is one of the European Union’s key objectives. In this context, geospatial data play a particularly important role, and are regulated by the INSPIRE directive and the Spatial Information Infrastructure Act in Poland. These data include, among others, the BDOT10k, GESUT, and orthophoto maps, which are widely available through geoportals and network services such as WMS and WFS. Up-to-date spatial information supports institutions, businesses, and citizens in planning and economic development. At the same time, the protection of critical infrastructure (CI) is becoming increasingly important. CI includes energy, telecommunication, financial, water, healthcare, transport, rescue, and administrative systems. Disruption in their functioning can lead to serious crises. Poland has implemented the National Critical Infrastructure Protection Program, which aims to ensure the security and continuity of these systems. This protection involves physical, technical, personnel, and teleinformation measures, with cyberattacks emerging as one of the most significant threats. The conclusions emphasise the need to balance open access to data with the protection of strategic information. In particular, access to data on high-capacity transmission networks should be restricted, while the physical and cyber protection of critical infrastructure must be strengthened. The current model of publishing geospatial data requires a thorough review and adjustment in the light contemporary threats.
