Keywords: International Telecommunication Union, ITU, digital divide, World Telecommunication Development Conference, WTDC, goal setting, trends, thematic priorities, regional initiatives.
The article considers the results of the World Telecommunication Development Conference 2022 (WTDC-22). The purpose of the study is to identify trends in the work of the Conference and the Telecommunication Development Sector of the International Telecommunication Union (ITU-D). The authors use the method of comparative analysis to highlight, among the main trends, a gradual transition from the implementation of the main technical functions and competencies of ITU-D towards socioeconomic topics that duplicate the work of other organizations of the UN family. The article discusses the change in the approach used to formulate the agenda of the Conferences and ITU-D priorities, which is reflected in the formation of ITU strategic planning documents and
determines the transfer of ITU-D priorities to the global level of goal setting for the entire ITU.

ONTOLOGY OF AUDITING THE EFFICIENCY OF PUBLIC ADMINISTRATION DIGITAL TRANSFORMATION PROJECTS
S.A. Korchivoy, FSBI NIIR, director of R&D Center, Ph.D.; korchivoysa@niir.ru
K.V. Frolov, FSBI NIIR, chief auditor; frolov@niir.ru
Keywords: information technology, ontology, IT audit, digital transformation, state information system.
A general methodology for assessing the effectiveness of complex technical objects in the field of information technology, as applied to the audit of state information resources and systems is presented. The methodology is intended for use by professional auditors, including in the framework of external state audit, control and supervision activities, technological audits, as well as operators of state information systems. The proposed IT audit ontology allows to form a knowledge base for the selection of indicators and performance indicators from the recommended set, taking into account the existing organizational, legal, technological constraints associated with the organization of baseline data collection for their evaluation, as well as to audit compliance with the requirements of the regulatory framework for a typical set of violations, taking into account a preliminary assessment of the probability of detection and the level of significance.

Keywords: interregional MNP, number portability between regions of the Russian Federation, saving a subscriber number.
At present, the subscriber phone number has actually become a unique identifier of a citizen not only as a user of communication services, but also for organizing and confirming access to various services (including government ones), portals, personal accounts, bank accounts, etc. Implementation of interregional number portability in the Russian Federation will significantly simplify the subscriber’s life during internal migration as well as finally abolish the «mobile slavery» in the Russian Federation. This article presents an analysis of the possibility on implementing the interregional number portability business-process, indicating statistical data, the results of the corresponding pilot project as well as proposals on possible approaches to the implementation of such the service throughout the country.
