Introducing thresholds in Security Event Alerting: a z-score love story
Aug 30, 2022Kristina Galicova
Summary
Introduced a threshold-based alerting mechanism for Security Event Alerts, complementing the existing z-score methodology. This new approach addresses the issue of zero-event domains triggering false positives by ensuring that alerts are only sent when the number of security events exceeds a predefined static threshold (200) AND crosses a z-score of 3.5. This hybrid approach aims to improve the accuracy and relevance of security alerts.
