Detection Finding

detection_finding

A Detection Finding describes detections or alerts generated by security products using correlation engines, detection engines or other methodologies. Note: if the event producer is a security control, the security_control profile should be applied and its attacks information, if present, should be duplicated into the finding_info object.
Note: If the Finding is an incident, i.e. requires incident workflow, also apply the incident profile or aggregate this finding into an Incident Finding.
