Assess alert fidelity, scope, impact, and urgency without losing the evidence behind the decision.

Operating context
Triage converts a machine-generated signal into a human decision. Analysts need sufficient entity, time, behavioral, and business context to distinguish benign activity from an incident.
- Define the security decision that alert triage must support.
- Assign accountable owners, escalation paths, service levels, and privacy boundaries.
- Measure signal quality, response consistency, operational cost, and improvement over time.
Operational workflow
- 01
Establish scope, dependencies, normal behavior, and a documented baseline.
- 02
Collect the minimum telemetry and context needed for alert triage.
- 03
Correlate independent signals and state confidence before taking disruptive action.
- 04
Document the decision, evidence, containment or control action, and responsible owner.
- 05
Review the outcome, tune the process, and validate the improvement with a safe test.
Signals, evidence & decisions
| Signal or artifact | Decision it supports |
|---|---|
| raw event and detection logic | Establish event sequence and affected scope. |
| entity timeline and asset criticality | Confirm identity, asset, or control context. |
| analyst disposition and rationale | Support containment, recovery, or tuning. |
Record source, timestamp, collection method, confidence, owner, and disposition. Preserve the smallest useful evidence set and document any uncertainty.
Implementation & improvement
- Use consistent severity and confidence definitions.
- Capture why an alert was closed or escalated.
- Sample closed alerts for quality review.
