Incident Triage

Incident Triage: Rapid classification and prioritization of a potential security incident. In practice, comprehensive data sourcesData SourceA system, sensor, log, or repository that supplies data for security analysis and decisions., transparent assessment criteriaEvaluation CriteriaExplicit criteria used to assess findings, alerts, controls, or risks consistently., qualified analystsSecurity AnalystA qualified specialist who investigates security data, findings, alerts, and incidents., and coordinated escalation pathsEscalation PathA defined route for transferring a security issue to the appropriate authority or expertise level. are crucial.

How it works and where it fits

Incident Triage belongs to a prepared workflow for handling security-relevant events. A technical signal becomes a substantiated incident only through triage, context, and assessment. Roles, decision authority, escalation paths, and stopping conditions should therefore be agreed in advance so actions remain consistent under time pressure.

Practical security relevance

Execution must balance rapid containment with careful evidence preservation. Actions should not unnecessarily destroy important traces or disrupt business operations without control. Timelines, decisions, and changes are documented; after recovery, root causes, identified gaps, and lessons learned feed back into controls, detection logic, and response plans.
