The paper formalizes the semantic representation of the common digital profile of IoT devices, containing knowledge about the architectural solutions of the Internet of Things, the criteria for analyzing the network activity of information exchange participants in the Publisher-Broker-Subscriber scheme and the characteristics of controlled physical processes. In order to select the concepts underlying the formalization, current research in the areas of cybersecurity and data analysis of the Internet of Things are considered. The author has formed an ontology containing the concepts of the subject area and their relationships, reflecting IoTtechnology and instances of concepts that describe the implementation of the Internet of Things network in the Krasnoyarsk Scientific Center. The described network is used to monitor technological rooms with telecommunications equipment and includes measuring devices, telecommunications environment, virtual and physical servers, and application software. The instances of objects in the ontology have its own digital representation in databases, contains measurement results, statistical and spectral characteristics of data, and is used to solve practical problems.
