Threats to critical infrastructure objects of Ukraine under martial law

The article is devoted to analyzing threats to Ukraine’s critical infrastructure. The relevance of the study is driven by the dangerous dynamics of threat levels that affect national security and the socio-economic stability of the state under martial law. A review of the scientific literature revealed that there is currently no unified approach to the classification and assessment of such threats. Therefore, the article aims to analyze existing classifications of threats to critical infrastructure and propose an original classification of their manifestations on critical infrastructure objects under martial law, considering both international and national experiences. During the research, several tasks were accomplished: the essence of the term «threat to critical infrastructure» was defined; an analysis of legal documents related to the protection of critical infrastructure was conducted; domestic and international experiences in threat classification were studied; principles underlying both domestic and foreign classifications were reviewed and their effectiveness was assessed; and an original classification of threats to critical infrastructure for Ukraine was developed. The results of the study revealed that there are various classifications of threats to critical infrastructure today. However, in our opinion, the most effective classification that meets modern challenges is one that considers all forms of their manifestations: physical assaults, cyberattacks, economic sabotage, terrorist actions, and assaults using climate weapons. This classification of threats to Ukraine’s critical infrastructure is developed based on international and domestic experience and is of great importance for enhancing national security, as its value lies in the systematization of theoretical knowledge and a deep analysis of modern threats facing the state. The main scientific value of the proposed classification lies in its ability to integrate different aspects of threats into a single classification that takes into account both internal and external factors. This allows for a more accurate risk assessment and the implementation of appropriate measures to protect national critical infrastructure objects.
