Question 60
An analyst reviews this Fortinet logging scenario: A backup SOC collector is reachable by ICMP, yet secure log forwarding fails with a certificate or negotiated-channel error. Which ongoing safeguard best addresses the original risk?
Explanation
Correct Answer
Test secure log-forwarding trust changes before rotating certificates or transport settings. This long-term control addresses the recurring risk. The technical reason is: A reachable IP path does not guarantee establishment of the authenticated or encrypted forwarding transport. A later acceptance test still needs to confirm: A sample record reaches the approved receiver over a verified secure channel and untrusted endpoints fail.
Incorrect Answers
This safeguard, “Monitor time sync and timestamp offsets across all logging components”, reduces a different source-defined risk: FortiAnalyzer archives contain events from a FortiGate after a WAN outage, but their timestamps differ markedly from the device's operational timeline. That risk depends on: Inconsistent device clocks distort event chronology even if log delivery and parsing are otherwise successful. The recurring problem here is a backup SOC collector is reachable by ICMP, yet secure log forwarding fails with a certificate or negotiated-channel error. The originally selected control “Test secure log-forwarding trust changes before rotating certificates or transport settings” is more specific because a reachable IP path does not guarantee establishment of the authenticated or encrypted forwarding transport.
This safeguard, “Validate VDOM identifiers and access scopes after virtual-domain redesign”, reduces a different source-defined risk: A FortiGate with multiple VDOMs sends messages, but an analyst cannot distinguish which tenant produced a particular security event. That risk depends on: Device serial alone may not identify a VDOM-specific policy context; source and virtual domain metadata affect analysis. The recurring problem here is a backup SOC collector is reachable by ICMP, yet secure log forwarding fails with a certificate or negotiated-channel error. The originally selected control “Test secure log-forwarding trust changes before rotating certificates or transport settings” is more specific because a reachable IP path does not guarantee establishment of the authenticated or encrypted forwarding transport.
This safeguard, “Forecast archive and Analytics consumption separately and alert before usable quota is exhausted”, reduces a different source-defined risk: An incident response workflow needs searchable historical traffic, but capacity planning reserves almost no disk for Analytics logs and allocates storage entirely to Archive. That risk depends on: Archive holds raw log files, while Analytics database storage supports indexed search, event handlers, and reports. The recurring problem here is a backup SOC collector is reachable by ICMP, yet secure log forwarding fails with a certificate or negotiated-channel error. The originally selected control “Test secure log-forwarding trust changes before rotating certificates or transport settings” is more specific because a reachable IP path does not guarantee establishment of the authenticated or encrypted forwarding transport.
