ES needs to be installed on a search head with which of the following options?

For the deployment of Enterprise Security (ES) in Splunk, it is essential to install it on a search head that is running compatible applications. The correct answer, which states that only default built-in and CIM-compliant apps should be installed alongside ES, highlights the importance of maintaining compatibility and ensuring that the security framework operates optimally.

Enterprise Security is designed to work seamlessly with the Common Information Model (CIM), which provides a standardized framework for data. By adhering to this framework and utilizing default built-in apps, Splunk ensures that data ingestion, normalization, and analysis are conducted appropriately, allowing ES to perform its functions without conflicts or errors.

Installing arbitrary third-party or custom-built applications could introduce discrepancies in how data is processed or accessed, potentially undermining ES’s effectiveness. It is vital for maintaining the integrity of security monitoring and incident response capabilities within the enterprise environment. This focus on default and CIM-compliant options helps guarantee that all data sources are correctly interpreted and used within the security context, thereby enhancing overall security posture.
