Recently I setup a bunch of apps to assist with malware analysis and realised that I didn't want to expose the applications to the internet directly and wanted a layer of authentication in between my applications and the internet and a reverse proxy was the solution is settled on.  Using OpenResty and Keycloak I was able to setup a single entry point for my web applications and have it serve as an authentication point before traffic is passed on to my apps preventing people from accessing them without first authenticating. Any requests to the sites will be redirected to an authentication portal where the user then signs on and then is redirected to the application.  Disclaimer : this guide is intended as a demonstration only and not intended for production systems.
