312-39 Proactive Threat Detection Practice Question
An organization has a SIEM and is struggling with 'alert fatigue.' What proactive measure should the SOC manager implement to improve the Signal-to-Noise ratio?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Implement multi-stage correlation rules that require high-confidence indicators to fire
Refining correlation rules to require multiple conditions (e.g., authentication failure followed by success) significantly improves alert fidelity.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Increase the retention period for all raw log data
Why it's wrong here
Retention improves storage, not the quality of the alerts generated.
- ✗
Lower the threshold for all IDS alerts to catch more threats
Why it's wrong here
This increases the noise and adds to alert fatigue.
- ✓
Implement multi-stage correlation rules that require high-confidence indicators to fire
Why this is correct
Reducing reliance on single-event triggers lowers noise while maintaining effective detection.
- ✗
Outsource all monitoring to a managed security provider
Why it's wrong here
This does not address the underlying issue of poor rule design within the SOC.
