In Splunk, indexers are designed to keep SSL and non-SSL data communications secure and distinct. This is crucial for maintaining data integrity and security. When SSL is enabled, it requires a secure layer of communication, which is fundamentally different from non-SSL communications.

Assigning separate ports for SSL and non-SSL traffic prevents any ambiguity in the communication protocols being used and reduces potential security vulnerabilities that may arise from improper handling of sensitive information. It helps in clearly defining the communication pathways and ensures that the protocols remain distinct without overlap, thus optimizing the security posture of the Splunk deployment.

While some configurations might allow for shared ports under certain circumstances, it doesn’t comply with best practices, which advocate for clear separation to avoid the risks associated with mixed traffic transmissions. Therefore, using separate ports is both a recommended and secure approach for setting up Splunk indexers.
