Summary/Abstract: The intensification of cyber threats has determined that information systems have become an essential axis of national security, and their protection is a strategic priority. This paper explores the methodological and operational relevance of the MITRE ATT&CK framework in the analysis of cyber risks, offering an integrated approach that correlates the tactics, techniques, and sub-techniques identified in the matrix with the most frequent forms of attacks observed at national and international levels. By applying unsupervised machine learning methods in the WEKA environment, operational data from MITRE was segmented into clusters in order to identify recurring behavioral patterns in cyber attacks. The article proposes an in-depth interpretation of these patterns, offering concrete recommendations for strengthening national cyber resilience, starting from the contextual analysis of the data and culminating with institutional, technological, and educational recommendations, in accordance with Romania's current security strategies.
