To reduce alert noise from repetitive SecOps alerts, which configuration should you apply?

• A. Modify YARA-L rules to use IC-Score.
• B. Configure alert grouping for repetitive alerts.
• C. Implement curated detections.
• D. Create a playbook to auto-tune IOC sources.

Answer: (B)

Grouping repetitive alerts into a single incident reduces alert noise by consolidating duplicates and related events. When the same activity triggers multiple alerts within a short period, grouping creates one incident that includes the common context and a count of occurrences. This makes it easier for analysts to triage, preserves the critical signals, and cuts down on fatigue from chasing the same issue repeatedly. You can tune the grouping with time windows and suppression rules to balance visibility with noise reduction.

Other options don’t directly address repetition. Changing YARA-L scoring alters how alerts are prioritized, not how duplicates are merged. Curated detections focus on selecting higher‑fidelity detections, which can reduce overall alert volume but not the continuous collapse of repeated alerts. Auto‑tuning IOC sources through a playbook automates data source management, but again doesn’t consolidate repeated alerts into a single actionable item.
