I wanted to know what is the best way to secure the Dataiku DSS instance Web and the Linux VM.
I wanted to use Azure Front Door to secure the Dataiku DSS Web Application and Azure Bastion for Linux VM.
Security should be handled in accordance to your corporate guidelines and existing toolset. The VM that will host DSS should be secured just like any other VM in your environment.
DSS has its own authentication mechanism but can also defer to LDAP if that's available on your end.
