Why Use "Data Models" for Standardized Search Accuracy and Detection Logic?
SplunkData Modelsprovide astructured, normalized representationof raw logs, improving:
✅Search consistency across different log sources✅Detection logic by ensuring standardized field names✅Faster and more efficient querieswith data model acceleration
????Example in Splunk Enterprise Security:????Scenario:A SOC team monitors login failures acrossmultiple authentication systems.✅Without Data Models:Different logs usesrc_ip, source_ip, or ip_address, making searches complex.✅With Data Models:All fieldsmap to a standard format, enablingconsistent detection logic.
Why Not the Other Options?
❌A. Field Extraction– Extracts fields from raw events butdoes not standardize field names across sources.❌C. Event Correlation– Detects relationships between logsbut doesn’t normalize data for search accuracy.❌D. Normalization Rules– A general term; Splunkuses CIM & Data Models for normalization.
