If You Can’t Measure it You Can’t Manage it - Quantitative Analysis of Cyber Risk Prediction and Mitigation
Bibliographic record
Abstract
Cyber breach incidents have increased dramatically during COVID-19 pandemic and keep a cyclical trend there after. Data breach incidents result in severe financial loss and reputational damage to business, government, healthcare and educational institutions. Compared to sufficient amount of cyber risk investigation in economic and IT system domain, seldom investigations of cyber risk have been made in quantitative perspective, In order to fill this gap, we propose a Bayesian generalized linear mixed model to analyze data breach incidents chronology since 2001. Our model captures the dependency between frequency and severity of cyber losses, and the behavior of cyber attacks on entities across time. Risk characteristics such as types of breach, types of organization, entity locations in chronology, as well as time trend effects are taken into consideration when investigating breach frequencies. A statistical predictive model is generated under actuarial mathematics frame, with flexible input available such as location and organization types. Predictions and implications of the proposed model in enterprise risk management and cyber insurance rate filing are discussed and illustrated. Our results show that both geological location and business type play significant roles in measuring cyber risks. The outcomes of our predictive analytics provide numerical currency loss level that can be utilized by various kinds of organizations and design their risk mitigation strategies.

How this classification was reachedexpand
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.
