That's a good point - if he's talking about securing the Solr filesystem, he can use standard mechanisms.
You can also go beyond user/group/other permissions if your filesystem supports it. You can use Posix ACLs on many local linux filesystems. -----Original Message----- From: Per Steffensen [mailto:st...@designware.dk] Sent: Tuesday, April 14, 2015 8:04 AM To: solr-user@lucene.apache.org Subject: Re: Securing solr index Hi I might misunderstand you, but if you are talking about securing the actual files/folders of the index, I do not think this is a Solr/Lucene concern. Use standard mechanisms of your OS. E.g. on linux/unix use chown, chgrp, chmod, sudo, apparmor etc - e.g. allowing only root to write the folders/files and sudo the user running Solr/Lucene to operate as root in this area. Even admins should not (normally) operate as root - that way they cannot write the files either. No one knows the root-password - except maybe for the super-super-admin, or you split the root-password in two and two admins know a part each, so that they have to both agree in order to operate as root. Be creative yourself.
