The authors propose the development of a framework using simulation modelling technology. The aim is to simulate the behavior and the interaction and interoperability of the components of the modern communication infrastructure of the national security systems in various crises. The focus is on cyber security and cyber defence, from the point of view of risks and threats to the security of communication infrastructure such as disasters and other crisis situations.

The report analyzes the needs and requirements of the National Situation Center (NSC) and the Crisis Management Center (CMC) regarding aspects of cyber security and cyber defense. The need for the interaction of the national security systems in crisis management, in order to ensure the functionality of the NSC and the CMC, is substantiated. For this purpose, it is important to define the critical entities in the national security ecosystem and to analyze the interactions between them according to legal documents and agencies and organizational structures of the European Union and Bulgaria. This, in turn, is a prerequisite for achieving effective and timely exchange of information, which will properly support the decision-making process in crisis management. The different types of cyber threats that could affect the operation of national security systems when crises occur, such as disasters, accidents and other crises are taken into account.

Achieving information security in the organization is related to the implementation of certain standard security procedures. The set of methods and tools for information security and communication and information systems (CIS) are the tools for implementing these procedures. The subject of the research is the subsystem for limiting and regulating access to information and communication and information systems, which is necessary for the analysis and simulation modelling of the interaction of national security systems in crisis situations related to cybersecurity and cyber defence.

In response to these global threats, it is essential that nations work together to develop coordinated approaches to ensure global security. This requires building trust, sharing information, and collaborating to develop effective solutions that address the root causes of these threats. One important step in ensuring global security is to focus on the prevention of crises before they occur. This can be achieved by investing in early warning systems, improving communication and cooperation between nations, and addressing the underlying causes of conflict and instability. Another key factor in ensuring global security is to promote sustainable development that prioritizes environmental protection, social justice, and economic progress. This can help to prevent resource scarcity and social inequality, which are often key drivers of conflict and insecurity. In addition, it is important to recognize the central role of technology in shaping global security. While technology can create new threats, it can also be harnessed to develop innovative solutions that promote global security. This includes investing in cybersecurity, developing new technologies to address environmental challenges, and promoting access to education and information to help people around the world build resilience and respond effectively to emerging threats. Global security is a complex and multifaceted issue that requires a coordinated and collaborative approach from nations around the world. By working together to prevent crises, promote sustainable development, and harness the power of technology, we can build a more secure and resilient world for generations to come.
