Best practice to access secure maven repository over the internet.

Issue

• We have configured our on-prem Fuse Fabric to pull down internally developed artifacts from our internal maven repository with a url such as

https://<almuser>:<password>@som.repo/artifactory/itservicesprod/@id=its.repo

• This is of-course configured in org.ops4j.pax.url.mvn.repositories in io.fabric8.agent.properties in default profile.
• We are now considering setting up a Fuse Fabric in AWS connecting to the same on-prem maven repo, and would like to know the best practice to connect to a secure maven repository over the internet, as the basic authn credentials are in the clear.
