By default, communication between Alfresco 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.
Every Alfresco 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
