What may be a necessary action before installing Enterprise Security?

Before installing Enterprise Security, ensuring that you have sufficient indexing capacity is crucial, which often means adding additional indexers. Enterprise Security generally handles a significant volume of security data that demands efficient indexing and searching capabilities. By scaling out your indexer environment, you can enhance performance, optimize search speeds, and ensure that your system can effectively manage the influx of data, especially during peak operational periods.

Increasing the number of indexers helps in balancing the load among multiple systems. This is particularly important when you consider the types of searches and reports that Enterprise Security generates, which can be resource-intensive. Proper indexing setup before installation also facilitates smoother deployments and minimizes the risks of performance bottlenecks afterward.

The other options, while they may play a role in the overall architecture or maintenance of a Splunk environment, do not directly address the essential requirement of sufficient indexing resources specifically in preparation for Enterprise Security.
