This paper critically analyses the escalating security challenges facing the European Union, primarily defined by the Russian Federation's military aggression against Ukraine after 2022 and the return of great power tensions. This transformation of the security environment has definitively ended the era of post-conflict peace on the European continent and exposed deep structural vulnerabilities in assuring sovereign European defence. The analysis identifies three key structural challenges: the critical fragmentation of Member States' defence capabilities and capacities, the limited ability to respond to high-intensity conflict, and the industrial unpreparedness of the European Defence Technological and Industrial Base. It is asserted that the EU’s persistent reliance on external guarantees, particularly amid rising transatlantic uncertainty, jeopardises its political sovereignty. To overcome these structural limitations, the paper advocates for a deeper integration trajectory towards the concept of a Total Defence Union. It posits that strengthening European defence is a strategic imperative for maintaining Europe's stability and international standing in an era of increasing great power rivalry.

The study includes an analysis of the functioning of micro, small and medium-sized enterprises during the COVID-19 pandemic from the perspective of financial security management of these entities. The article covers the identification of threats in the area of finances of the discussed enterprises that arose during the pandemic, as well as the assessment and approach to financial risk management in these entities. As a result, the key categories of threats to the financial security of enterprises, arising during the COVID-19 pandemic, were presented, as well as the assessment of the effectiveness of state services responsible for ensuring financial security. The study focuses on multidimensional data analysis in terms of their grouping and unraveling in terms of comparing the considered variables in terms of dynamics. Initial studies were performed by comparing several variables, and the data were analyzed not only during the COVID-19 pandemic, but also in the pre-pandemic period in terms of observing their fluctuations in dynamic terms, and the relationships between them were also examined.

Security of societies has become one of urgent issues in contemporary world. Too frequently we started encountering one or another form of malicious behavior, criminal activities or terrorism. New and complex threats highlight the need for further synergies and closer cooperation at all levels. Awareness, preparedness and resilience of societies emerge as key preconditions of further secure and sustainable economic development and general well-being. A special attention in those conditions has to be paid to development of theoretically grounded approach to protection of critical infrastructure (CIP), damage or disruption of which can be immensely harmful to unprepared and therefore vulnerable institutions and society. The aim of this paper is to lay theoretical foundations for theoretically grounded approach towards research in CIP area, in order to formulate, ultimately, an approach towards action, which, employing leadership societal stakeholders would allow to enhance awareness of society actors about the threats, i.e, to develop ability to recognize, prevent, and, in case of disaster, to resist to consequences of critical infrastructure infringement. Hence, enhanced resilience of society to critical infrastructure infringement is and ultimate goal of fostering of leadership for critical infrastructure protection.

Security and competitiveness are two very important aspects of the economic and political development of every country. In the 21st century, one of the key drivers of most economies in countries throughout the world is energy. Different countries adopt different measures so as to ensure their security and competitiveness through the effective energy policies that make traditional and renewable resources adequately available hence eliminating the possibilities of shortages. Our paper takes up the case study of Germany as one of the wealthiest and most developed economies in the European Union which also occupies the first positions in the charts of energy uptake and consumption. German policy-makers realize its vulnerability when it comes to energy security and attempt to diversify its energy competitiveness using the renewable sources of energy (for instance via the adoption of the Erneuerbare-Energien-Gesetz or the “Renewable Energy Act” (EEG)). We analyze the issues of energy security and competitiveness of a country using an example of Germany. Moreover, we describe what challenges the renewable energy sources (RES) might bring into the conventional game and how this might influence the competitiveness and security.

Our paper aims at analysing and assessing sustainable housing policy and social security in selected countries of the European Union with a special focus on housing policy which largerly depends on the family support and family policy of the EU Member States. Family policy and family support allow young families to acquire their own housing and therefore represent a key element in the bundle of the social-oriented state policies.
