Restricting access to Kafka metadata in Zookeeper
Learn how to restrict access to Kafka metadata in Zookeeper.
Locking down Kafka znodes (metadata) in Zookeeper can be used to protect Kafka metadata against unauthorized access. Direct manipulation of metadata in Zookeeper is not only dangerous for the health of the cluster, but can also serve as an entry point for malicious users to gain elevated. Access to Kafka metadata in Zookeeper is restricted by default. Follow these steps if you have previously unlocked access, but want to re-enable access restrictions.
A secure Kafka cluster with Kerberos authentication enabled is required.
