The paper presents the results of test studies of a software tool (ST) for monitoring the current state of a defined
group of DNS servers. To improve the informative content and timeliness of test measurement data analysis, artificial
intelligence (AI) capabilities are integrated, enabling flexible adjustment of test structures and profiles. The improved ST
increases situational awareness regarding security threats in DNS traffic. The experimental version implements cloudbased multi-source measurements using spatially distributed cloud sensors, centrally controlled via an administrator
console. This architecture allows monitoring DNS query processing parameters from simulated clients located in different
domain zones. Within the framework of simulation modeling for various DNS query encryption protocols, the parameters
of the daily availability of servers were evaluated. The results confirmed the system’s ability to automatically adapt
measurement parameters and structure based on real-time AI analytics of previous observations. The generalization of
the obtained information has made it possible to identify promising directions for further improvement of the implemented
concept, including: enhancing the administrative procedures of the cloud bot-testers system; refining the specifics inherent
to different AI systems in accordance with the monitoring tasks performed; formalizing criteria for assessing the current
state of DNS traffic; improving precedent-based analysis mechanisms for detecting anomalous traffic; enhancing the
procedures for synthesizing new scenarios to detect previously unknown threats exploiting DNS traffic (services and
applications) vulnerabilities.
Keywords: DNS, RPZ, AI, information security, traffic filtering.
