A security alert is a signal that asks a person or workflow to review activity. It may come from a SIEM, endpoint tool, cloud platform, identity service, employee, customer, or vendor.
A useful alert record includes:
- Detection time and source
- Triggering event or rule
- Affected asset, user, or service
- Severity or confidence supplied by the source
- Related alerts and known context
- Current owner and next action
An alert is not proof that an incident occurred. The response team still needs to validate the signal, remove duplicates, add context, and assess impact. This is why alert management and incident management should be connected without treating every alert as an incident.
For a practical example, see how Microsoft Sentinel incidents can feed a better response workflow.
