Abstract:
Critical information infrastructure exists in different sectors of each country. Its loss or
sustainability violation will lead to a negative impact on the supply of essential services, as well as
on the social or economic well-being of the population. It also may even pose a threat to people’s
health and lives. In the modern world, such infrastructure is more vulnerable and unstable than ever,
due to rapid technological changes, and the emergence of a new type of threat—information threats.
It is necessary to determine which infrastructure are of crucial importance when decision-makers
aim to achieve the reliability of essential infrastructure. This article aims to solve the problem of
ensuring the sustainable development of EU countries in terms of identifying critical information
infrastructures. Integrated multi-criteria decision-making techniques based on fuzzy WASPAS and
AHP methods are used to identify essential information infrastructures, which are related to a new
type of potential threat to national security. The paper proposes a model for identifying critical
information infrastructures, taking into account the sustainable development of countries.
