The article analyzes the healthcare sector as a strategic target in hybrid conflicts, with a focus on cyber threats. Based on OSINT and a comparative analysis of incidents, it identifies typical attack patterns, their operational impacts, and systemic vulnerabilities in healthcare systems. The findings demonstrate that cyber incidents disrupt healthcare delivery and have broader security implications. The study emphasizes the need to integrate cybersecurity, crisis management, and the protection of sensitive patient data.

The rapid spread of unmanned aerial vehicles and loitering munitions has created a new class of threats for critical infrastructure, especially for facilities that depend on uninterrupted operation and contain exposed roof and wall assemblies. In such an environment, the design of protective systems can no longer focus only on conventional lateral threats or on isolated single-impact scenarios. Instead, it must address repeated fragmentation exposure, localized cumulative damage, and the need to preserve functionality after attack. This paper develops a standalone conference contribution based primarily on the ballistic material evaluation presented in Chapter 5 of the source study. The text focuses on the structural characteristics, test response, and engineering applicability of rigid glass-fiber-reinforced polymer (GFRP) panels and flexible Twaron T730 aramid systems for infrastructure protection. Two GFRP panels with nominal thicknesses of 12.2 mm and 14 mm were evaluated under ballistic loading, while rear-face deformation was measured by laser profilometry and internal damage was assessed using digital radiography. In parallel, a multilayer Twaron T730 aramid configuration was used as a comparative flexible barrier system. The results confirm that rigid GFRP panels provide stable mechanical resistance, controlled rear-face deformation, and a low probability of catastrophic penetration under the tested conditions. The radiographic evaluation further shows that internal damage zones can significantly exceed visibly damaged areas, highlighting the importance of non-destructive inspection for reliable post-impact assessment. The aramid system demonstrates favorable energy absorption under moderate impact loading, but it also reaches its limits under repeated higher-energy events. Based on the combined results, the paper argues that rigid composite panels are the most suitable primary protective element for large-area infrastructure applications, while aramid systems are best employed as supplementary internal layers or as part of a hybrid configuration. The findings are discussed in relation to roof protection, multi-hit resistance, modular retrofitting, and the practical design of protective envelopes for critical infrastructure exposed to fragmentation hazards.

9/11 made terrorism a part of everyday life on a global basis, attacking civilisation as a whole. As a result, the activity of terrorist organisations reduces people’s sense of security even in their everyday lives, by randomly attacking high public density targets with a huge emotional and publicity impact. The states cannot guarantee security through their law enforcement agencies alone, as the sources of danger have multiplied and become more unpredictable. Therefore, it is more important than ever to involve communities, social organisations, economic and market actors in maintaining common security. Private security thus plays by now an extremely important role in completing public order and security. The radicalisation trend within the terrorist organisations results in a growing number of internal terrorism threats. Given that terrorists aim to choose targets with a likely “success” of their acts, it is important to highlight those whose partial, temporary or total downtime entails consequences which would also make other infrastructures inoperative. Those who from these aspects turn to be the most important, and their continuous and well-functioning operation are essential to the operation of other infrastructures, are called critical infrastructures. If we put the above phenomena together, a clear conflict emerges: critical infrastructure protection, although in most cases not state owned, is also a common security issue, protected mostly by private security services, employing people mainly trained for private security tasks. Our article highlights this problem introducing the scientific background, also suggesting a possible solution for evaluation.

With the changing global security situation, increase in external threats or emergence of new ones (cyberattacks, onconventional warfare models, etc.), countries must feel concern regarding consolidation of their security (e.g. Novikovas et al. 2017; Šišulák 2017). The fight against terrorism and the mitigation of climate change are key challenges facing global social changing. The issue of climate change is in synergy with the concepts of ecological, economic and energy security. Global development increasing demand of energy, triggered by increasing population and respective increase of economic activities, and consequent environmental degradation (Tvaronavičienė, 2016). Climate change and increasing human activities posing a serious threat to the ecological security in different fields (Li et al. 2017). Terrorist attacks in the USA, floods in 2002, shaped new attention EU Institution to Critical Infrastructure (CI) concept, as an element of security. Critical infrastructure, as a phenomenon (for example energy), has become an argument in making political decisions (Tvaronavičienė, 2012). One of the ecological security elements is municipal waste management, which, as a business sector, is characterized as a complex phenomenon, which includes: infrastructure-engineering, administrative-functional, political and technological aspects. The aim of the topic is to analyze the municipal waste management sector as a phenomenon of national security. The topic reveals theoretical insights of the municipal waste management sector, identified it as a critical infrastructure object, in the context of Lithuanian national security. The object - peculiarities of legal regulation of critical infrastructure in EU and Lithuanian legal acts. The authors applied scientific methods such as document analysis, teleological, critical-analysis, comparative and generalization.
