Following this thought, and unlike the dimensions of political, strategic, and organisational culture, we believe it is appropriate to introduce a new use of the term culture within the concept of security culture. This should enable us to identify certain behaviours related to security within the system as a whole, its individual parts within specific groups(subcultures), as well as at key points of security initiative and decision-making primarily at the level of the state, but also involving other entities(organisations, groups, individu­als). Culture and behavioural rules in security change, develop, and become more complex in accordance with the changing role of the state and the transformation of the security environment within or outside the state’s territory, including changes in the character of security threats and risks. These changes also trigger the emergence of new actors and the altered roles of existing actors in security, whose security interests are aligned with cultural factors. The cultures they possess and exhibit internally and to­wards one another can influence how they define and achieve their goals. Even in stable circumstances, culture determines and sustains a whole rep­ertoire of attitudes and responses based on beliefs and habits that prevail within the state or are established among states in their mutual relations. The extent to which norms and ideas can be used to explain certain out­comes remains open for future reflection and the crossing of different view­points on this issue. However, through various illustrations in this work, we will demonstrate the complexity of these possibilities that are available to analysts and researchers. The Concept of Security The conceptualization of security is also undergoing profound changes, rooted in a new way of thinking about and practicing security. This new approach aims to enable a safer, more just, and better-organised society and state. In the new millennium, under the conditions of emerging se­curity challenges, risks, and threats, these changes are significantly more difficult but also more demanding in terms of new approaches and forms of resistance, especially evident in preventive strategies, concepts, and specific measures. Like culture, security is complex; it has both a theoretical and a practical dimension and establishes connections with other dimensions as well as with numerous other concepts. The term“security” is also an“essen­tially contentious concept,” particularly when it becomes a field of political conflicts. 36 NATIONAL SECURITY CULTURES- A VIEW FROM THE BALKANS
