This report presents an innovative application of simulation modelling as an immersive technology in education, employing the "learning by doing" methodology. Simulation modelling serves as a powerful instrumental analysis method, enabling the study of an organization's information infrastructure cybersecurity, including during crisis situations. Using specialized software applications, a simulation model of the organization's communication and information system is developed. Through conducted experiments and simulations of predictive scenarios, it becomes possible to accurately estimate the time until service failure occurs.

Based on these results, cybersecurity specialists or trainees can update applied technical and organizational measures related to cybersecurity policies. Subsequent simulations verify the resistance against cyber attacks for the organization's information infrastructure. To facilitate this process, an example model of the organization's information infrastructure was developed using the Riverbed Modeler Academic Edition simulation software. A denial-of-service attack was simulated on the system, with two predictive scenarios exploring the effects of varying attack parameters on two exemplary network configurations.

This approach allows for assessing the impact of cyber attacks, informing decisions regarding appropriate protection measures in the design and operation of information systems. As a result, educators and researchers gain valuable insights into the practical implications of cybersecurity threats, enhancing both teaching and learning experiences. By focusing on the educational aspect, this study contributes to the development of effective cybersecurity training programs and fosters a deeper understanding of the subject matter among students and professionals alike.
