FortiSIEM Architecture: The FortiSIEM architecture includes several components such as Supervisors, Workers, Collectors, and Agents, each playing a distinct role in the SIEM ecosystem.
Real-Time Event Correlation: Real-time event correlation is a critical function that involves analyzing and correlating incoming events to detect patterns indicative of security incidents or operational issues.
Role of Supervisor and Worker:
* Supervisor: The Supervisor oversees the entire FortiSIEM system, coordinating the processing and analysis of events.
* Worker: Workers are responsible for processing and correlating the events received from Collectors and Agents.
Collaboration for Correlation: Together, the Supervisor and Worker components perform real-time event correlation by distributing the load and ensuring efficient processing of events to identify incidents in real-time.
References: FortiSIEM 6.3 User Guide, Event Correlation and Processing section, details how the Supervisor and Worker components collaborate for real-time event correlation.

Event Type Population: In FortiSIEM, the Event Type field is populated based on specific identifiers within the raw message or event log.
Raw Message Analysis: The exhibit shows a raw message with various components, includingPH_DEV_MON_SYS_DISK_UTIL,PHL_INFO,phPerfJob, anddiskUtil.
Primary Event Identifier: ThePH_DEV_MON_SYS_DISK_UTILat the beginning of the raw message is the primary identifier for the event type. It categorizes the type of event, in this case, a system disk utilization monitoring event.
Event Type Field: FortiSIEM uses this primary identifier to populate the Event Type field, providing a clear categorization of the event.
References: FortiSIEM 6.3 User Guide, Event Processing and Event Types section, details how event types are identified and populated in the system.

Monitor Column Indicators: In FortiSIEM, the Monitor column displays the status of various metrics applied during the discovery process.
Yellow Star Meaning: A yellow star next to a metric indicates that the metric was successfully applied during discovery and data has been collected for that metric.
Successful Data Collection: This visual indicator helps administrators quickly identify which metrics are active and have data available for analysis.
