Annotation: This study is aimed at a comprehensive review of the security problem of the Domain Name System (DNS) in the context of the Industrial Internet of Things (IIoT), where limited computing resources of devices are combined with high requirements for reliability and fault tolerance. A comparative analysis of specialized DNS protection protocols is presented, including DNSSEC, DoH, DoT, DoQ, as well as lightweight solutions such as DoC and mDNS, applicable under resource-limited conditions. The protocols were tested both in a virtualized environ- ment and on a microcontroller, enabling an assessment of their efficiency across different infrastructure levels. A scientific and methodological approach to the analysis of DNS protection protocols within the framework of the industrial Internet of Things is proposed, including the following procedures: the forming of a classification of cyberattacks on DNS in an industrial environment; the introduction of a semi-quantitative risk assessment model adapted to conditions of limited computing power; the comparison of traditional and lightweight protocols based on practical experiments. The investigation results can be applied to the selection of DNS security protocols in industrial systems, as well as in educational and methodological contexts.
