Question 80
A security operations team receives this change request: A third-party web server sends raw messages to a Fabric ADOM, but Log View All lacks normalized source-address fields for cross-product analysis. Which ongoing safeguard best addresses the original risk?
Explanation
Correct Answer
Test parser support whenever a third-party product changes its log format. This long-term control addresses the recurring risk. The technical reason is: A suitable parser maps incoming records into normalized Fabric fields before they can populate the SIEM database. A later acceptance test still needs to confirm: The test web event appears in normalized All logs with a populated source address and event category.
Incorrect Answers
This safeguard, “Version-control source JSON examples and parser field-path mappings”, reduces a different source-defined risk: A cloud proxy emits JSON log records with nested user and risk properties, but the existing plain-text extraction fails to populate fields. That risk depends on: Structured JSON paths differ from flat delimiter extraction, so a parser built for one format need not read another. The recurring problem here is a third-party web server sends raw messages to a Fabric ADOM, but Log View All lacks normalized source-address fields for cross-product analysis. The originally selected control “Test parser support whenever a third-party product changes its log format” is more specific because a suitable parser maps incoming records into normalized Fabric fields before they can populate the SIEM database.
This safeguard, “Review normalized queries for both field matching and access-scope restrictions”, reduces a different source-defined risk: A multi-vendor authentication investigation searches by normalized username but returns administrator logins from an unrelated tenant due to missing ADOM scoping. That risk depends on: Normalization makes heterogeneous fields comparable but does not supersede tenant and source authorization boundaries. The recurring problem here is a third-party web server sends raw messages to a Fabric ADOM, but Log View All lacks normalized source-address fields for cross-product analysis. The originally selected control “Test parser support whenever a third-party product changes its log format” is more specific because a suitable parser maps incoming records into normalized Fabric fields before they can populate the SIEM database.
This safeguard, “Inventory supported log sources and required parser entitlements during onboarding”, reduces a different source-defined risk: FortiAnalyzer receives an unsupported third-party application format and the operator assumes buying a generic SIEM license automatically creates a matching parser. That risk depends on: A Security Automation Service entitlement can offer parser downloads, but unknown formats still require an actual matching and enabled parser. The recurring problem here is a third-party web server sends raw messages to a Fabric ADOM, but Log View All lacks normalized source-address fields for cross-product analysis. The originally selected control “Test parser support whenever a third-party product changes its log format” is more specific because a suitable parser maps incoming records into normalized Fabric fields before they can populate the SIEM database.
