The research focuses on studying the features of mixed (discrete-continuous) data transmission channels and the specifics of using GUI interfaces used in modern administration scenarios. The paper considers formal models for processing behavioral signs, suggests an approach to integrating asynchronous and fragmentary signals, and performs a comparative analysis of biometric methods based on stability criteria, the possibilities of application in background modes, and the possibility of integration without additional equipment. Particular attention is paid to the architectural requirements for Continuous Authentication Systems (CAS), including assessing the adaptability of models and determining their resistance to data flow fragmentation. The analysis results confirm that mouse dynamics has balanced characteristics for passive biometric authentication.: It is actively used in software and hardware platforms with a graphical interface, does not require specialized sensors, and provides good identification quality with a low level of interference. It is shown that this type of biometric authentication can be effectively applied in conditions of an unstable channel, while meeting the requirements for synchronization, aggregation and profile adaptation. The proposed recommendations on the architecture of CAS systems are focused on real-world application in the IT infrastructure without compromising performance and user experience.</p></abstract><trans-abstract xml:lang="ru"><p>Целью данной работы является обоснование возможностей применения динамики мыши как метода поведенческой биометрии для задач непрерывной аутентификации системных администраторов в условиях удаленного доступа. Исследование ориентировано на изучение особенностей смешанных (дискретно-непрерывных) каналов передачи данных и специфики использования GUI-интерфейсов, применяемых в современных сценариях администрирования. В работе рассмотрены формальные модели обработки поведенческих признаков, предложен подход к интеграции асинхронных и фрагментарных сигналов, выполнен сравнительный анализ биометрических методов по критериям устойчивости, возможностей применения в фоновых режимах и возможности интеграции без дополнительного оборудования. Особое внимание уделено архитектурным требованиям к системам непрерывной аутентификации (Continuous Authentication Systems, CAS), включая оценку адаптивности моделей и определение их устойчивости к фрагментации потока данных. Результаты анализа подтверждают, что динамика мыши обладает сбалансированными характеристиками для пассивной биометрической аутентификации: активно используется в программно-аппаратных платформах с графическим интерфейсом, не требует специализированных сенсоров, обеспечивает хорошее качество идентификации при низком уровне вмешательства. Показано, что данный тип биометрической аутентификации может быть эффективно применен в условиях нестабильного канала, при соблюдении требований к синхронизации, агрегации и адаптации профиля. Предложенные рекомендации по архитектуре систем CAS ориентированы на реальное применение в ИТ-инфраструктуре без ущерба для производительности и наличия пользовательского опыта.</p></trans-abstract><kwd-group xml:lang="en"><kwd>behavioral biometrics</kwd><kwd>mouse dynamics</kwd><kwd>continuous authentication</kwd><kwd>remote access</kwd><kwd>mixed signals</kwd><kwd>Continuous Authentication Systems (CAS)</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>поведенческая биометрия</kwd><kwd>динамика мыши</kwd><kwd>непрерывная аутентификация</kwd><kwd>удаленный доступ</kwd><kwd>смешанные сигналы</kwd><kwd>Continuous Authentication Systems (CAS)</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Almohri H.M.J., Yao D., Kafura D.
