Apache Kafka uses Access Control Lists (ACLs) to manage authorization. ACLs specify which clients are allowed or denied access to specific resources, such as topics, consumer groups, or clusters, based on their principal name (authenticated identity). Kafka’s ACLs allow fine-grained control over permissions like read, write, and delete. Custom authorization models can also be implemented by configuring Kafka’s authorizer class. This ensures that only authorized users can perform certain actions within the Kafka ecosystem.
Apache Kafka supports several authentication methods, including TLS Client Authentication (Mutual TLS), SASL (Simple Authentication and Security Layer) with mechanisms like PLAIN, SCRAM, GSSAPI (Kerberos), and OAUTHBEARER. Each of these methods ensures that only authorized clients can connect to the Kafka cluster. Organizations can choose the authentication mechanism that best fits their security needs, including integrating with OAuth2 or existing Kerberos servers for centralized management.
