Hi Vinay,

I've pulled my colleague Gordon into the conversation who can probably tell you more about Flink's security features.

Cheers,

Hi,

Currently I am looking into configuring in-transit data encryption either
using Flink SSL Setup or directly using EMR.

Few Doubts:
   1. Will the existing functionality provided by Amazon to configure
in-transit data encrytion work for Flink as well. This is explained here:
http://docs.aws.amazon.com/emr/latest/ReleaseGuide/emr-encryption-enable-security-configuration.html
http://docs.aws.amazon.com/emr/latest/ReleaseGuide/emr-data-encryption-options.html#emr-encryption-intransit

   2. Using Flink SSL Setup: as we know only the IP address of master node
on EMR , should we pass only its ip address in the SAN list as given here ?
(I think it should work as the yarn-cli command will distribute the
truststore and keystore to each TM )
https://ci.apache.org/projects/flink/flink-docs-release-1.3/setup/security-ssl.html#use-yarn-cli-to-deploy-the-keystores-and-truststore

Vinay Patil
