Openfire Security and Hardening

Hello all,

So I need to secure/harden openfire but I cannot seem to find any documentation or guide on how to harden openfire. The closest I’ve come across would be this site which does not look very legit or complete…
https://wiki.xmpp.org/web/Securing_XMPP
I also don’t see any guides that are relevant in the documentation repository in the link below, apart from maybe the SSL guide.
https://download.igniterealtime.org/openfire/docs/latest/documentation/index.html

Hence I was wondering if anyone knows whether there is an official hardening guide for openfire and if there is then where can I find it. Otherwise, any unofficial guide or any recommendations on best practices for security would suffice.

Thankyou!
