Configuring Kafka Streams For Least Privilege

Gwen Shapira explains how we can assign minimal rights to Kafka Streams and KSQL users:

The principle of least privilege dictates that each user and application will have the minimal privileges required to do their job. When applied to Apache Kafka® and its Streams API, it usually means that each team and application will have read and write access only to a selected few relevant topics.

Organizations need to balance developer velocity and security, which means that each organization will likely have their own requirements and best practices for access control.

There are two simple patterns you can use to easily configure the right privileges for any Kafka Streams application—one provides tighter security, and the other is for more agile organizations. First, we’ll start with a bit of background on why configuring proper privileges for Kafka Streams applications was challenging in the past.
