Worked on enhancing Filebeat’s Redis input within the elastic/beats repository by implementing support for username and password authentication, enabling compatibility with ACL-based Redis deployments. Utilized Go to modify backend logic so that Filebeat can securely connect to Redis instances requiring authentication, addressing both operational security and deployment flexibility. Developed comprehensive integration tests to verify successful and failed authentication scenarios, ensuring robust validation across multiple credential configurations. Focused on backend development, authentication, and networking, this work improved the reliability and security of Redis-backed data streams, reducing operational risk for users who depend on Redis as a primary data source in their workflows.
