Exam SC-200 Topic 2 Question 298 Discussion

Explanation:

Microsoft Sentinel uses the Advanced Security Information Model (ASIM) to normalize logs into a consistent schema, enabling unified queries, analytics rules, and hunting queries across multiple data sources.
Each ASIM function has a structured parser hierarchy , typically consisting of:
* A master (or orchestrator) parser , which aggregates and calls all source-specific parsers.
* Source-specific parsers , which map raw data from each data source (like Windows SecurityEvents, Sysmon, or custom logs) to the ASIM schema fields.
In the case of ProcessCreate events:
* _Im_ProcessCreate is the master parser . Its role is to call all ProcessCreate parsers , including both built-in and custom ones (for example, imProcessCreate , vimProcessCreate , or other vendor-specific parsers).
* Parsers like imProcessCreate (for native sources) and vimProcessCreate (for custom or vendor-specific sources) are source-specific parsers . They are responsible for standardizing and mapping raw fields into the ASIM Process schema , ensuring consistent naming such as ActorProcessName , TargetProcessName , and TargetProcessCommandLine .
"The _Im_ functions are orchestrators that call all source-specific parsers. Each im or vim parser converts native data into the ASIM schema for its respective source." Therefore:
* To call all ProcessCreate parsers , modify _Im_ProcessCreate .
* To standardize fields to the Process schema , modify vimProcessCreate (the new source-specific parser you created).
# Final Answers:
* Call all the ProcessCreate parsers: _Im_ProcessCreate
* Standardize fields to the Process schema: vimProcessCreate
