From Data to Action: CTI Analysis and ATT&CK Technique Correlation

Cyber Threat Intelligence (CTI) significantly enhances organizational cybersecurity defenses by providing actionable insights from diverse data sources. This research studies the correlation between CTI analysis and the MITRE ATT&CK framework, focusing on their alignment to strengthen threat detection and response capabilities. A pivotal aspect of this study involves developing a classifier using a fine-tuned BERT-based model to map CTI reports to specific ATT&CK techniques. Our model demonstrated substantial improvements over the baseline SecBERT, achieving a 2.6% higher F1-score and a 4.2% improvement in Top-3 Accuracy. By integrating CTI with the MITRE ATT&CK framework, researchers can shift from reactive to proactive cybersecurity strategies. This integration enables swift detection of emerging threats, enhances incident response effectiveness, and fortifies defensive measures against evolving cyber threats. Ultimately, the synergy between CTI and ATT&CK fosters a comprehensive approach to cybersecurity management in today’s dynamic threat landscape.
