Question 400
During a review of an enterprise SOC workflow, the administrator finds: A threat chart reports zero detections, but raw IPS events are visible only in Archive and not in the Analytics store for the period. Which ongoing safeguard best addresses the original risk?
Explanation
Correct Answer
Set Analytics retention according to the report's maximum lookback requirement. This long-term control addresses the recurring risk. The technical reason is: Report generation relies on analyzable data; retained archive files alone need not feed ordinary Analytics datasets. A later acceptance test still needs to confirm: The required time-period data is available in the report's query source and counts become nonzero.
Incorrect Answers
This safeguard, “Perform a section-inclusion preview for all deliverable report templates”, reduces a different source-defined risk: An exported report PDF is available but the requested chart is not visible because its containing section was disabled in the chosen template. That risk depends on: Report layout and section selection determine which otherwise valid chart objects are included in output. The recurring problem here is a threat chart reports zero detections, but raw IPS events are visible only in Archive and not in the Analytics store for the period. The originally selected control “Set Analytics retention according to the report's maximum lookback requirement” is more specific because report generation relies on analyzable data; retained archive files alone need not feed ordinary Analytics datasets.
This safeguard, “Regression-test report grouping fields whenever parsers are updated”, reduces a different source-defined risk: A report's bar chart suddenly shows one unclassified category after a log parser update, while raw event counts stay consistent. That risk depends on: A grouping field that becomes null or changes meaning can collapse distinct rows into an unknown category. The recurring problem here is a threat chart reports zero detections, but raw IPS events are visible only in Archive and not in the Analytics store for the period. The originally selected control “Set Analytics retention according to the report's maximum lookback requirement” is more specific because report generation relies on analyzable data; retained archive files alone need not feed ordinary Analytics datasets.
This safeguard, “Audit device-group membership when renaming or replacing reporting sources”, reduces a different source-defined risk: An incident report appears to omit a compromised IP because the source filter was set to a similarly named FortiGate group. That risk depends on: Report device filters select specific logging sources; similar names do not guarantee matching source membership. The recurring problem here is a threat chart reports zero detections, but raw IPS events are visible only in Archive and not in the Analytics store for the period. The originally selected control “Set Analytics retention according to the report's maximum lookback requirement” is more specific because report generation relies on analyzable data; retained archive files alone need not feed ordinary Analytics datasets.
