Github user StephanEwen commented on the issue:
https://github.com/apache/flink/pull/5966
I would move ahead with this PR as follows:
- Separate internal and external SSL config
- Activate SSL client auth for akka, netty, and blob server (pure
internal communication)
Let's discuss external connectivity on FLIP-26
> Perform mutual authentication during SSL handshakes

> Key: FLINK-9312
> URL: https://issues.apache.org/jira/browse/FLINK-9312
> Project: Flink
> Issue Type: New Feature
> Components: Security
> Reporter: Stephan Ewen
> Priority: Major
> Fix For: 1.6.0
>
>
> Currently, the Flink processes encrypted connections via SSL:
> - Data exchange TM - TM
> - RPC JM - TM
> - Blob Service JM - TM
> However, the server side always accepts any client to build up the
> connection, meaning the connections are not strongly authenticated.
> Activating SSL mutual authentication solves that - only processes that have
> the same certificate can connect.
