Kafka Summit 2016 | Operations Track

Kafka was originally developed at LinkedIn in 2010. It was originally an open system to encourage adoption; developers could easily create new data streams, add data to the pipeline, and read data as it was created. It succeeded brilliantly at encouraging developers to build new data applications, improved the reliability of systems and applications, and helped LinkedIn scale it’s logging and data infrastructure.

Unfortunately, as Kafka usage grew at LinkedIn (and at other sites), we discovered problems with a totally open system. Developers might inadvertently cause production problems when creating new Kafka streams, engineers might change the configuration of critical systems, and employees might get access to sensitive data. As Kafka has been adopted by larger enterprises with more complex security requirements, we have had to rethink our architecture.

In this talk, we will explain how we have secured Apache Kafka. We will explain the threats that Kafka Security mitigates, the changes that we made to Kafka to enable security, and the steps required to secure an existing Kafka cluster.

  • Specifically, we will cover:
  • New security features in Kafka 0.9
  • The risks and threats with a distributed data streaming system
  • Common issues with deploying a secure Kafka system
  • The access control model for Kafka
  • Configuring authentication, access control, and encryption
  • Using a secure Kafka cluster with other secure (and insecure) systems
  • Testing, monitoring and tuning a secure Kafka cluster
  • Future work in Kafka security
