Remote access to NiFi UI in secure setup

[Saip, Alexander (NIH/CC/BTRIS) [C]]

We are just starting with NiFi. Currently, there is a single-node instance 
running on a CentOS server. Without any security configuration, I am able to 
connect to the NiFi UI from the Chrome browser running on my Windows desktop. 
In order to enable multi-tenancy, we have to secure NiFi. The NiFi System 
Administrator's Guide mentions the TLS Toolkit, but exclusively in the context 
of NiFi cluster. I wonder if there is a way for me to enable HTTPS connections 
to the NiFi UI from a remote computer that is NOT a cluster node? If yes, what 
would be the best way to achieve that?
