event_type: Selects the payload schema.
flow_id: Flow correlation identifier; preserve numeric precision.
timestamp: Event time with offset.
alert: Rule-match context when present.

Investigation uses

Correlate flow_id and event_type with related protocol and alert records.
For alerts, review signature, action and packet context before assigning a verdict.

Validation boundaries

An alert is a rule match, not independently confirmed compromise. Fields and nested structures differ by event type and version.

This sample passed byte-integrity and JSON/XML parsing checks, including the catalogue’s specified event discriminators. This is not a complete vendor-schema validation or a tested detection.

For a simulation, first parse this fixture offline, then create a separately labelled synthetic variant and test it against the intended collector in an isolated lab. Never replay public example identities or destinations into production.
