Decision Tree Example: Impact of Loss Data Type Victim Country > $10M Integrity > $10M External Relationship <= $10M Pattern <= $10M <= $10M > $10M
Decision Tree Example: Prediction predict(impact_loss, newdata = test) <= $10 Mil > $10 Mil 1 0.9797297 0.02027027 3 0.9797297 0.02027027 4 0.3333333 0.66666667 10 0.3333333 0.66666667 15 0.9797297 0.02027027 17 0.9797297 0.02027027 19 0.9797297 0.02027027 25 0.9797297 0.02027027 27 0.9797297 0.02027027 28 0.9797297 0.02027027 33 0.4444444 0.55555556 44 0.9797297 0.02027027 45 0.9797297 0.02027027 48 0.97972970.02027027 49 0.3333333 0.66666667
Decision Tree Example: Prediction Confusion Matrix – Comparison summary of predicted results versus observed results in a classification model. Accuracy – fraction of instances that were correctly classified. = (79 + 3) / 99 = 0.828 or 82.8%
Decision Tree Example: Data Imbalance in R • Oversample or Undersamplethe Data • Changing Prior Probabilities • Including a Loss Matrix
Continuing Challenges of Cybersecurity • Constantly Evolving Nature of Cyber Security Industry • Growth of Online Assets • Growing Sophistication of Hackers • Proactive vs. Retroactive
