Kafka and authentication

Hi All,

I was googling around for info on securing kafka. The best document I could find was https://cwiki.apache.org/confluence/display/KAFKA/Security, which is “kind of old”. It is not clear if any steps were taken after this doc was put together. Looking at the features / bug fixes in kafka also does not paint a clear picture. Hence this set of questions :

Is there a way to make kafka authenticate a producer sending messages / consumer reading messages ?
Is there a way to make kafka authenticate itself to the ZooKeeper ensemble ?

Any info will be deeply appreciated

Thanks

Vijay
