This allows for faster classification and disposition of events. Often, non-normalized logs are archived for historical query and forensic purposes.Log aggregation function: This aggregates common log information and reduces duplicate logs.Log correlation function: This should be one of the more important functions of SIEM. This feature means that the SIEM platform links events in different formats generated by various systems at different times to create a single event with actionable information for security analysts or security administrators.
