What is Alert Triage?

Triage is borrowed from emergency medicine: rapidly assess patients to prioritize care by urgency. In the SOC, analysts cannot investigate every alert with equal depth simultaneously. You quickly assess each alert's potential severity, gather enough evidence to classify it, and either close (false positive), remediate (self-contained issue), or escalate (complex or severe incident).

A structured triage process: read the alert details and initial context. Pivot to the relevant tool (SIEM logs, EDR telemetry, network flows) to gather supporting evidence. Assess the affected asset's criticality. Check threat intelligence for involved IOCs. Make a classification decision with documented rationale. Time management is critical. Spending too long on any single alert risks missing others in the queue.

SLA targets govern triage timelines. Most SOC contracts specify maximum time-to-acknowledge and time-to-initial-investigation thresholds by severity tier. Missing SLA on critical alerts is a major operational failure with contractual and reputational consequences.
