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.

Collecting SIEM and PAM Events: To collect both SIEM event logs and Performance and Availability Monitoring (PAM) events from a Microsoft Windows server, a suitable protocol must be selected.
WMI Protocol: Windows Management Instrumentation (WMI) is the appropriate protocol for this task.
* SIEM Event Logs: WMI can collect security, application, and system logs from Windows devices.
* PAM Events: WMI can also gather performance metrics, such as CPU usage, memory utilization, and disk activity.
Comprehensive Data Collection: Using WMI ensures that both types of data are collected efficiently from the Windows server.
References: FortiSIEM 6.3 User Guide, Data Collection Methods section, which details the use of WMI for collecting various types of logs and performance metrics.
