This article explores the roles of severity and confidence in detection alerts within cybersecurity operations, emphasizing their proper use and potential misuse. It discusses how to improve detection accuracy and prioritize responses effectively through metrics like a unified “alert priority” score. #DetectionRules #ConfidenceScores
Keypoints
- Severity indicates the potential impact of a security alert, while confidence measures the certainty of its maliciousness.
- Misuse of confidence scores includes conflating them with severity, defaulting to medium confidence, and misinterpreting low confidence as false positives.
- A single, unified alert priority score can improve consistency and clarity for security analysts.
- In in-house teams, confidence is less critical due to detailed knowledge and tuning, whereas MSSPs rely on confidence to manage scale.
- Effective detection engineering involves balanced trade-offs, operational clarity, and proper application of metrics like confidence and severity.
