In a SOC process, what do the transitions "Event → Alert → Incident" mean?

Raw observations are Events; sensors and tooling raise an Alert worth a human look; confirmed harmful alerts become an Incident requiring response.

This maps the data pipeline of a SOC. A Service Desk or SOC platform ingests log data from on-prem, infrastructure and cloud sources, enriching and scoring it — those are Events. When automated detection rules fire, the system produces an Alert (Service Desk / SOC platform). Analysts then investigate: L1 filters false positives and registers real ones; L2 analyses and escalates; the resulting confirmed case is an Incident that drives the investigate/react/respond and improve phases. The flow ends in actions for the customer and feedback to improve detection.
