Reducing Alert Fatigue in the SOC Using Correlation Rules and Detection-as-Code

Alert fatigue in a security operations center tends to appear when alerts outpace the ability to validate them with confidence, creating desensitization and burnout while increasing the chance that the rare high-signal alert is handled too slowly. Practitioner research on SOC alarm validation describes this work as tedious and emphasizes that “false positive” is often an imprecise label, because many alarms are better understood as benign triggers that match a detection condition but are tolerated in the local environment.  Correlation rules and detection-as-code reduce fatigue by shifting escalation away from isolated event matches and toward repeatable, reviewable patterns and thresholds.  

When alerts become noise rather than signal

Fatigue is frequently framed as too many alerts, but the tractable engineering problem is too many alerts that require human validation. The same qualitative study reports that analysts are often required to decide the accuracy of alerts produced by automated systems, that alarm validation involves repetitive manual work, and that excessive alarms can contribute to desensitization, mistrust, and reduced responsiveness.
