Abstract: The paper is devoted to the systematization of modern methods for feature extraction and anomaly detection based on the analysis of operating system logs to address the problem of extended authentication. Approaches to processing and structuring system logs are reviewed and classified, including the extraction of quantitative, index, semantic, temporal, parametric, and graph features. An overview of open datasets for log analysis is provided. The authors performed a comparative analysis of the effectiveness of various feature extraction methods and anomaly detection algorithms, encompassing statistical methods, classical machine learning, neural networks, and hybrid models. Effectiveness was evaluated in terms of the performance metrics of classifiers solving the final task. The most promising areas for developing extended authentication systems are identified. The research results can be applied to to enhance the security of information systems through the development of adaptive authentication mechanisms based on user activity monitoring.
