Question 480
A FortiAnalyzer administration handover records the following: A predefined intrusion event handler is present in the catalog but does not produce events after fresh matching FortiGate attack logs arrive. Which ongoing safeguard best addresses the original risk?
Explanation
Correct Answer
Monitor enabled handler inventory after new ADOM creation or migration. This long-term control addresses the recurring risk. The technical reason is: Some predefined handlers are disabled until activated; matching source logs are insufficient while the handler or its scope is inactive. A later acceptance test still needs to confirm: After enabling it and checking scope, a controlled attack log produces the expected event.
Incorrect Answers
This safeguard, “Test event ordering and timeout windows whenever backup workflows change”, reduces a different source-defined risk: A SOC wants an alert if a failed backup occurs and no recovery confirmation arrives within the allowed interval. That risk depends on: A negative temporal relationship can detect the absence of a required follow-up event after a preceding event. The recurring problem here is a predefined intrusion event handler is present in the catalog but does not produce events after fresh matching FortiGate attack logs arrive. The originally selected control “Monitor enabled handler inventory after new ADOM creation or migration” is more specific because some predefined handlers are disabled until activated; matching source logs are insufficient while the handler or its scope is inactive.
This safeguard, “Version-control custom handler changes and avoid overwriting reference baselines without approval”, reduces a different source-defined risk: Analysts need a tailored brute-force rule modeled on a Fortinet predefined handler without losing the ability to restore the vendor default. That risk depends on: Cloning preserves the stock detection definition while allowing a separately managed customized rule. The recurring problem here is a predefined intrusion event handler is present in the catalog but does not produce events after fresh matching FortiGate attack logs arrive. The originally selected control “Monitor enabled handler inventory after new ADOM creation or migration” is more specific because some predefined handlers are disabled until activated; matching source logs are insufficient while the handler or its scope is inactive.
This safeguard, “Validate selectors with genuine representative source logs before production activation”, reduces a different source-defined risk: An event handler works in the lab but misses production FortiMail activity after copying its selector from a FortiGate-only policy. That risk depends on: An event handler only evaluates records within its device, log-type, and filter selection. The recurring problem here is a predefined intrusion event handler is present in the catalog but does not produce events after fresh matching FortiGate attack logs arrive. The originally selected control “Monitor enabled handler inventory after new ADOM creation or migration” is more specific because some predefined handlers are disabled until activated; matching source logs are insufficient while the handler or its scope is inactive.
