Abstract
Network security is seriously threatened by distributed denial-of-service (DDoS) attacks, which calls for sophisticated intrusion detection systems that can rapidly identify and mitigate such threats. Despite their widespread use in intrusion detection against DDoS attacks, machine learning methods still suffer accuracy degradation due to inadequate data pre-processing and computational inefficiency. This study combined a fine-tuned extreme gradient boosting (XGBoost) model with correlation-based feature selection—for efficient feature selection—to effectively maximize detection accuracy while lowering computing overhead. Both correlation-based feature selection and XGBoost contribute to boosting the final model's efficiency. To evaluate the proposed model, different metrics were employed over three DDoS data sets, considering both binary and multi-classification scenarios. Experimental findings demonstrate that the proposed XGBoost achieves highly competitive accuracy. For the Network Security Laboratory–Knowledge Discovery Databases data set, University of New South Wales–Network Behavior15 data set, and Canadian Institute for Cybersecurity–Intrusion Detection System–2017 data set, the model secures 0.995, 1.000, and 0.999 and 0.996, 0.885, 0.998 for binary and multi-classification, respectively, outperforming its rival models.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
