Выявление внутренних угроз в контексте данного исследования сводится к решению задачи детектирования аномалий в журналах аудита действий субъектов доступа. В статье формализованы основные направления выявления внутренних угроз, приведены популярные алгоритмы машинного обучения. В работе поднимается проблема объективной оценки результатов исследований и разработок в данной предметной области.  На основании проведенного анализа разработаны рекомендации по реализации систем выявления внутренних угроз с помощью алгоритмов машинного обучения.</p></abstract><trans-abstract xml:lang="en"><p>This paper presents an analysis of algorithms and approaches used to solve the problem of identifying insider threats using machine learning techniques. Internal threat detection in the context of this research is reduced to the task of detecting anomalies in the audit logs of access subjects' actions. The paper formalizes the main directions of insider threats detection and presents popular machine learning algorithms. The paper raises the problem of objective evaluation of research and development in the subject area. Based on the analysis recommendations for the implementation of internal threat detection systems using machine learning algorithms are developed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>внутренние угрозы информационной безопасности</kwd><kwd>машинное обучение</kwd><kwd>поиск аномалий</kwd><kwd>аутентификация</kwd><kwd>изоляционный лес</kwd><kwd>ансамблевые методы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>internal threats to information security</kwd><kwd>machine learning</kwd><kwd>anomaly hunting</kwd><kwd>authentication</kwd><kwd>isolation forest</kwd><kwd>ensemble methods</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">РНФ</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">A.
