i am just testing univention server. Never tried it before. It looks interesting. At the moment I have got a kopano-server running at a rootserver (private use only).
Now I am thinking of using the univentionserver instead of the kopano-server, because with univention it seems to be a lot easier, if you want to install additional software.
As the kopano-server (root-server) is directly connected to the internet I wonder whether I can do the same with the univention server. The kopano-server (@debian) is “protected” by updates, monitoring and ufw-firewallrules (only a few ports can go out / in).
Long term short:
Is the univention built for direct installation on a rootserver which is directly reachable from the internet?
Is it safe to use univention server @ a root-server (directly connected to the internet)?
Is there a possibility to protect the univention-server, when doing it that way? (Firewall, automatic updates, monitoring…)
Is the univention server “secure by design” right after installation?
Thanks a lot!
