This paper emphasizes the key role of creating a security protection plan for business entities, which significantly affects the continuity and success of business processes and functions. In the first part, the paper focuses on understanding the basic concepts of security protection, including physical, technical and mechanical protection. Physical protection refers to physical barriers and space surveillance, technical protection includes technologies such as encryption and firewalls, while mechanical protection includes security systems such as locking and alarm systems. The analysis in the paper shows that for effective security it is necessary to establish and implement a detailed security protection plan. This plan includes risk analysis and the development of additional plans and a threat management strategy. Although the creation of a security protection plan and risk analysis are not legally mandatory for all economic entities, they are key documents that help economic entities identify potential threats and develop effective strategies for their management. The case study of cyber-attacks in the Republic of Croatia and the world highlights the seriousness of the threats that such attacks can represent for business systems, as well as the consequences. This study highlights the importance of adequate prevention and development of a recovery plan from cyberattacks that are becoming more common. The implementation of preventive measures and recovery plans is essential for minimizing damage and ensuring the resilience of business processes and functions to unforeseen incidents, thereby increasing business security and stability.
