 Device Discovery in FortiSIEM: Device discovery is the process by which FortiSIEM identifies and adds devices to its management scope.

 Role of Collectors: Collectors are responsible for gathering data from network devices, including discovering new devices in the network.

Functionality: Collectors use protocols such as SNMP, WMI, and others to discover devices and gather their details.

 Capability: While agents (Windows and Linux) primarily gather data from their host systems, the collectors actively discover devices across the network.

 References: FortiSIEM 6.3 User Guide, Device Discovery section, which details the role of collectors in discovering network devices.

 Case Sensitivity in Searches: In FortiSIEM, search queries, including those for raw event logs, are case sensitive. This means that keywords must be entered exactly as they appear in the logs.

 Keyword Mismatch: The exhibit shows the keyword "TCP" in the Value field. If the actual events use "tcp" (lowercase), the search will return no results because of the case mismatch.

 Correct Keyword: To match the keyword correctly, the administrator should enter "tcp" in the Value field.

 References: FortiSIEM 6.3 User Guide, Search and Filtering section, which discusses the importance of case sensitivity in search queries.

 Performance and Availability Monitoring: Various components in FortiSIEM are responsible for monitoring the performance and availability of devices and services.

 Components:

Supervisor: Oversees the entire FortiSIEM infrastructure and coordinates the activities of other components.

Worker: Processes and analyzes the collected data, including performance and availability metrics.

Collector: Gathers performance and availability data from devices in the network.

 Collaborative Functioning: These components work together to ensure comprehensive monitoring of the network's performance and availability.
