Question 240
An incident responder must address this situation: An endpoint's login records use both `Admin` and `admin`, but the team wants to distinguish their literal case for an application-specific account audit. Which ongoing safeguard best addresses the original risk?
Explanation
Correct Answer
Document case-sensitive investigation requirements for application identities. This long-term control addresses the recurring risk. The technical reason is: Log View searching is usually case insensitive; toggling sensitivity changes whether case variants are treated as matches. A later acceptance test still needs to confirm: The case-sensitive query returns only the intended form and the alternate spelling can be queried separately.
Incorrect Answers
This safeguard, “Pair negative search findings with log-source availability checks”, reduces a different source-defined risk: A hunt finds no malicious traffic during a three-hour window, but FortiAnalyzer Log Receive Monitor shows a branch stopped sending logs for two hours. That risk depends on: No query results cannot establish no threat activity when data ingestion was incomplete. The recurring problem here is an endpoint's login records use both `Admin` and `admin`, but the team wants to distinguish their literal case for an application-specific account audit. The originally selected control “Document case-sensitive investigation requirements for application identities” is more specific because log View searching is usually case insensitive; toggling sensitivity changes whether case variants are treated as matches.
This safeguard, “Assign ownership and review cycles to shared investigation custom views”, reduces a different source-defined risk: A security analyst needs a recurring review of the same high-risk source subnet, but rebuilds an intricate device and action query every shift with inconsistent terms. That risk depends on: Custom views preserve analyst search context and can be private or shared, reducing differences between repeated searches. The recurring problem here is an endpoint's login records use both `Admin` and `admin`, but the team wants to distinguish their literal case for an application-specific account audit. The originally selected control “Document case-sensitive investigation requirements for application identities” is more specific because log View searching is usually case insensitive; toggling sensitivity changes whether case variants are treated as matches.
This safeguard, “Audit device NTP and export time formats during cross-device investigations”, reduces a different source-defined risk: Security teams compare logs from two appliances but one exported timestamp is device local time and the other is UTC, creating an apparent impossible event order. That risk depends on: Log chronology depends on reliable event timestamps and timezone interpretation, not just displayed row order. The recurring problem here is an endpoint's login records use both `Admin` and `admin`, but the team wants to distinguish their literal case for an application-specific account audit. The originally selected control “Document case-sensitive investigation requirements for application identities” is more specific because log View searching is usually case insensitive; toggling sensitivity changes whether case variants are treated as matches.
