>                 Key: KAFKA-4864
>                 URL: https://issues.apache.org/jira/browse/KAFKA-4864
>             Project: Kafka
>          Issue Type: Bug
>    Affects Versions: 0.10.1.0, 0.10.1.1, 0.10.2.0
>            Reporter: Stephane Maarek
>            Priority: Critical
>             Fix For: 0.11.0.0, 0.10.2.1

> It seems that the secure nodes as referred by ZkUtils.scala are the following:
> https://github.com/apache/kafka/blob/trunk/core/src/main/scala/kafka/utils/ZkUtils.scala#L201
> A couple things:
> - the list is highly outdated, and for example the most important nodes such as kafka-acls
don't get secured. That's a huge security risk. Would it be better to just secure all the
nodes recursively from the given root?
> - the root of some nodes aren't secured. Ex: /brokers (but many others).
> The result is the following after running the tool:
> zookeeper-security-migration --zookeeper.acl secure --zookeeper.connect zoo1:2181/kafka-test
> [zk: localhost:2181(CONNECTED) 9] getAcl /kafka-test/brokers
> 'world,'anyone
> : cdrwa
> [zk: localhost:2181(CONNECTED) 11] getAcl /kafka-test/brokers/ids
> 'world,'anyone
> : r
> 'sasl,'myzkclient@EXAMPLE.COM
> : cdrwa
> [zk: localhost:2181(CONNECTED) 16] getAcl /kafka-test/kafka-acl
> 'world,'anyone
> : cdrwa
> That seems pretty bad to be honest... A fast enough ZkClient could delete some root nodes,
and create the nodes they like before the Acls get set.
