What can you use to send data to FortiSIEM for user and entity behavior analytics...

The correct answer is A. FortiSIEM agent. The FortiSIEM Study Guide identifies FortiSIEM agents as the component responsible for “file, log monitoring, and UEBA.” It also explains that FortiSIEM agents can be installed on endpoints or servers to provide data collection functions that native syslog may not provide. For Windows systems specifically, the guide states that Windows servers do not natively send syslog messages and that a FortiSIEM Windows agent can be installed to perform that function. The FortiSIEM 7.4 User Guide also confirms that FortiInsight UEBA functionality runs as an integrated module within the FortiSIEM Windows Agent in newer releases. SSH and SNMP are access or monitoring protocols; they can support discovery or performance monitoring, but they are not the UEBA data-sending component. A FortiSIEM worker performs analysis and search functions inside the FortiSIEM architecture; it is not installed on endpoints to collect UEBA telemetry. Therefore, the FortiSIEM agent is the correct mechanism for sending UEBA-relevant endpoint data to FortiSIEM.
