Dr. Bob Sohval, Director of Data Science at SecurityScorecard, details class imbalance challenges when training machine learning models for breach prediction.
“The number of non-breached companies, the ratio of non-breached to breached is something like, in our system or our platform, something like a thousand to one.”

Insight
Cyber breach prediction is more accurate on portfolios than individual companies
“And I would say that, ah, in general, breach prediction on portfolios is somewhat easier than for individual entities. The law of large numbers does apply here, and it's easier to make statements at a portfolio level.”

AssertionNot checkable as stated
Companies with poor security scores are five times more likely to breach
“Of the probability of a breach given a poor score versus a good score, and we look at our data, and that is a ratio of five, something like that. So poor scores are predictive of breach.”
