Cyber education has been one of the global challenges in recent years. Attacks are becoming more sophisticated, and it is increasingly difficult to provide a safe working environment. Hyper-realistic virtual environments called cyber ranges help increase the level of cybersecurity training. Access to multi-domain exercises is needed to make full use of their capabilities, combine information technology networks and other appropriate infrastructure. A systematic review of the modern cyber ranges used for teaching and research purposes in higher education institutions has been made. This study aims to analyse cyber range characteristics, functionalities, and requirements for their implementation and integration in accordance with the EU regulations. The results will be used in the development of a conceptual model for a cybersecurity training laboratory at the University of National and World Economy, Sofia, Bulgaria. Its inclusion in the teaching and research process is a relevant, important, and promising area for the future of higher educaiton in cybersecurity.
