Use Cloud SIEM Event Management to monitor the events triggered by Logz.io Cloud SIEM security rules.
With a single source of truth, you have visibility into the triggered security events in your environment, to track triggered event rules, set the event status, assign an event handler, and use comments to add information, and prioritize how those issues are handled.
The events are displayed in a table: You can sort the events table by severity, status, handler, initial triggering date, and the last time the event was updated or edited. You can also filter and search the events in the table, to further refine your results.

|Assigned to||Team member handling event investigation and resolution|
|Status||Investigation stage of the triggered event:

Searching for events
You can run a free text Search on the information in the Event details field - This includes any of the information in the event title, ID, or Description.
If you’re running a search and no events are displayed, try adjusting your search terms to find what you’re looking for. It might also be that no events were triggered during the time frame you selected.
Editing an event
You can update the following event fields:
- The investigation Status of the event.
- The investigator the event is Assigned to. Once an event is assigned to a team member, the assignment can’t be reset to Unassigned.
- Add text to the Comment field, to provide information about the event investigation, the handling process, or task priorities.
After an investigator edits an event, the date and user are automatically displayed in the Updated field for the event.
