Cybersecurity system evaluation and configuration

Abstract

Statistical properties of known malware distributions may be used to improve estimates of malware detection metrics such as a base rate of malicious events in a target environment or missed detections (also referred to as false negatives). In particular, numerous synthetic sample distributions may be generated based on the statistical properties of a base data set and/or additional observed data, and used to identify malware distributions that produce overall detection statistics corresponding to model output for live target data. The malware detection metrics for the live target data can then be characterized using the observed distributions of malware (and malware detections) for the synthetic sample distributions.
