Sets up TLS/SSL configurations for inter-Splunk communication. Add the following stanzas and settings to the file. In the nf file, configure the instance to use the server certificate.Use a text editor to open the $SPLUNK_HOME/etc/system/local/nf configuration file for editing.For example, you can move the files to a destination directory of $SPLUNK_HOME/etc/auth/mycerts/. Using this prompt or file system management tools, copy the server certificate and the certificate authority public certificate into an accessible directory on the instance where you want to configure certificates.You can configure TLS certificates on Splunk services that use the management network port. An understanding of Splunk configuration filesĬonfigure TLS certificates for communications on the Splunk management port.Administrative access to the Splunk Enterprise instances that you want to secure.The key files that come with the certificates must comply with the Rivest-Shamir-Adelman (RSA) security algorithm.You must have a private key file for each certificate file.The certificates must be in Privacy-Enhanced Mail format and comply with the x.509 public key certificate standard.After you get the certificates, you must prepare the certificates for use with Splunk platform instances.You can either obtain third party certificates from a certificate authority, or create and sign them yourself.Prerequisites for configuring TLS certificates for inter-Splunk communicationīefore you can secure communications between Splunk indexers and forwarders, you must have the following: You can either obtain certificates from a certificate authority, or create and sign them yourself.

The certificates you use can replace the default certificates that Splunk provides. This port is also known as the Splunk management port. Typically, Splunk processes communicate on the TCP/IP network port 8089. This is known as inter-Splunk communication. You can use transport layer security (TLS) certificates to secure connections between various Splunk components. Configure TLS certificates for inter-Splunk communication
