A critical SIEM integration requires specific custom fields from Windows Event Logs (ingested via Winlogbeat and XSIAM's EDR integration) to be normalized into XSIAM's Common Information Model (CIM). After a recent XSIAM content update, these fields are no longer mapping correctly. The raw logs in XSIAM show the custom fields are present and correctly ingested. What is the most effective troubleshooting approach to restore the correct CIM normalization?
Correct Answer: B
If raw logs are present and fields are visible but CIM normalization is failing after a content update, the issue lies in the normalization rules or field mappings. XSIAM content updates can sometimes introduce changes that override or conflict with existing custom configurations. Option B directly addresses checking and correcting these mappings within the XSIAM console. Option A is unnecessary if raw logs are present. Option C and D address capacity/retention, not mapping logic. Option E is a last resort and dangerous without explicit vendor guidance.
