Advanced Cyber-Physical Attack Classification with Extreme Gradient Boosting for Smart Transmission Grids
Bibliographic record
Abstract
The power grids are transforming into the cyber-physical smart grid with increasing two-way communications and abundant data flows. Despite the efficiency and reliability promised by this transformation, the growing threats and incidences of cyber attacks targeting the physical power systems have exposed severe vulnerabilities. To detect and identify attack threats from the heterogeneous cyber-physical information in the smart grid, this paper proposes an ensemble learning-based attack classifier using extreme gradient boosting (XGBoost). Compare with the popular single-classifier based approaches, the XG Boost-based attack classifier can effectively learn from the multi-sourced data to pinpoint attacks from normal and fault scenarios. Considering the potential imbalance of data samples among normal, fault, and attack samples, the paper also utilizes imbalance learning technique to boost the balance of data and subsequently the performance of XGboost. The proposed classifier is evaluated on a cyber-physical power system dataset collected from a high-fidelity hardware-in-the-loop smart grid testbed. The overall classification accuracy achieves over 99%, an effective 4% increase over the state-of-the-art, while maintaining over 95% accuracy in more complex, dynamic scenarios.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
