What is Triage?
In SOC operations, triage is the initial assessment where analysts rapidly evaluate an alert to determine severity, validity, and response priority, enabling the team to allocate investigation resources to the most critical threats first.

How Triage Works
SOC triage mirrors emergency medical triage: quickly assess severity and urgency so critical conditions receive immediate attention while lower-priority issues queue for later. Without effective triage, a high-severity incident can be buried under false positives, causing dangerous response delays.
The decision tree: Is this a true positive? (initial investigation for supporting evidence) What is the severity? (based on asset criticality, attack stage, potential impact) What is the urgency? (active attack or historical detection?) Who handles it? (L1 for false-positive validation, L2 for complex investigations, L3/IR team for confirmed high-severity incidents).
Metrics govern performance: MTTD, MTTA (Mean Time to Acknowledge), and MTTR. SLA breach on critical alert triage is a major operational failure. You make triage decisions efficiently without cutting investigative corners that would cause missed threats.
Triage in SOC Operations
Triage speed and accuracy are the metrics most directly under your control. SOCSimulator measures both: how quickly you classify alerts and whether classifications are correct. Building triage intuition, recognizing common false-positive patterns, knowing when an alert needs thirty seconds versus thirty minutes, and identifying the key pivot points for each alert type, is what separates efficient analysts from those who treat every alert identically.
