Access Control Lists (ACLs) enable Kafka Administrators to define and manage permissions for Kafka resources. ACLs determine the operations that authenticated users are allowed to perform on specific Kafka resources, providing fine-grained access control across the Kafka cluster. In Condense, ACLs are managed through the Kafka Administration interface and are mapped to users based on their assigned Condense roles.

​
Overview

The ACL Management page provides a centralized interface for viewing and managing access policies for Kafka resources. Kafka Administrators can:
  • View existing ACL entries.
  • Review user permissions for Kafka resources.
  • Update permission types.
  • Remove existing ACL entries.
  • Monitor the status of ACL assignments.
ACLs are displayed in a tabular format, allowing administrators to review permissions for each user and resource.

​
ACL Information

Each ACL entry contains the following information. Permission is initially set to Deny until it is explicitly updated by a Kafka Administrator.

​
ACL States

ACLs progress through different states depending on resource availability and administrator actions. When an ACL entry is deleted, it is removed from the ACL list.

​
Permission Types

ACL Management supports the following permission types. New ACL entries default to Deny until updated by a Kafka Administrator.

​
Supported Kafka Resources

ACLs can be configured for supported Kafka resources, including:
  • Topics
  • Consumer Groups
Additional resource types may be supported depending on the Kafka deployment.

​
Managing ACLs

Kafka Administrators can:
  • Review ACL entries.
  • Update permission types.
  • Modify resource assignments.
  • Remove ACL entries when access is no longer required.
Changes take effect after the updated ACL configuration is saved.

​
Best Practices

  • Grant only the permissions required for users to perform their responsibilities.
  • Review ACL assignments regularly.
  • Remove obsolete ACL entries.
  • Use predefined Condense roles to simplify permission management.
  • Verify resource assignments before updating permissions.
