* Understanding the Event Handler Configuration:
* The event handler is set up to detect specific security incidents, such as spearphishing, based on logs forwarded from other Fortinet products like FortiSandbox.
* An event handler includes rules that define the conditions under which an event should be triggered.
* Analyzing the Current Configuration:
* The current event handler is named "Spearphishing handler" with a rule titled "Spearphishing Rule 1".
* The log viewer shows that logs are being forwarded by FortiSandbox but no events are generated by FortiAnalyzer.
* Key Components of Event Handling:
* Log Type: Determines which type of logs will trigger the event handler.
* Data Selector: Specifies the criteria that logs must meet to trigger an event.
* Automation Stitch: Optional actions that can be triggered when an event occurs.
* Notifications: Defines how alerts are communicated when an event is detected.
* Issue Identification:
* Since FortiSandbox logs are correctly forwarded but no event is generated, the issue likely lies in the data selector configuration or log type matching.
* The data selector must be configured to include logs forwarded by FortiSandbox.
* Solution:
* B. Configure a FortiSandbox data selector and add it to the event handler:
* By configuring a data selector specifically for FortiSandbox logs and adding it to the event handler, FortiAnalyzer can accurately identify and trigger events based on the forwarded logs.
* Steps to Implement the Solution:
* Step 1: Go to the Event Handler settings in FortiAnalyzer.
* Step 2: Add a new data selector that includes criteria matching the logs forwarded by FortiSandbox (e.g., log subtype, malware detection details).
* Step 3: Link this data selector to the existing spearphishing event handler.
* Step 4: Save the configuration and test to ensure events are now being generated.
* Conclusion:
* The correct configuration of a FortiSandbox data selector within the event handler ensures that FortiAnalyzer can generate events based on relevant logs.
