By default, communication between repository and Solr is protected by SSL with mutual
authentication. Both the repository and Solr have their own standard public/private key pair. To
secure the two-way communication between the repository and Solr, you must generate your own
keys.
Note: Every installation is supplied with a generic certificate and SSL keys. For security
reasons, it is advised that you generate a new set of keys to secure you Solr communication and
access to the Solr Admin Console. For more information, see Configuring Solr and Generating secure
keys for Solr communication.
