Cybersecurity training of IT specialists and cybersecurity awareness for other employees are the first steps in creating effective cyber defence. These two types of educations must be provided in a realistic environment for which the computer virtualization is the best choice. The purpose of this article is to present a concept for building and developing a fully functional Security Operations and Training Centre (SOTC) at Nikola Vaptsarov Naval Academy (NVNA). This SOTC will operate as a training environment for IT specialists and as a Security Operations Centre for the academy’s computer network. The author presents all design steps that must be implemented during establishing and enhancing the SOTC at NVNA, including key resource requirements and utilised technologies.
