For members of society, cyberspace has become an indispensable scene of their communication and everyday interaction, thus contributing to the emergence and functioning of the global information society. Depending on the stage of their lives in which the members of each generation have encountered ICT tools, different qualities, skills, abilities and expectations can be observed in them. The members of the Y, the Z, and now the alpha generation have a completely different set of values and adaptability than their predecessors. From the point of view of the national security services, it is important to examine the main characteristics of these generations and social groups, since among other things, the newly recruited members of the national security services are members of society. In order to ensure the operation of effective national security services based on traditional values, knowledge and age specifics, it is necessary to optimize recruitment systems that meet the needs of the next generation and are able to attract their attention and measure their suitability. The aim of this publication is to identify the main groups of challenges and to formulate possible solutions that can support the efficiency of both selection and recruitment activities for each national security service.
