    Proactive Cyber Resilience: A Unified Assessment Methodology for Incident Forecasting With Cyber Threat Intelligence Integration by Hayat Abdulla Asad Cue, Thirimachos Bourlai, Mark Lupo

    Published 2025-01-01
    “…To address some of the limitations introduced by our real-world dataset’s scarcity and unbalanced characteristics, we expanded the number of observations 15 times by generating and balancing over 200 synthetic assessment results using Random-OverSampling and SMOTE. Experimental results show that synthetic data contribute positively to identifying risk categories based on cybersecurity posture scores below 45/100 and above 61/100, predicting additional attack techniques under variable implementation conditions, such as T1027, and confirming a multifold reduction in assessment time from months to days.…”
