What is Kerberos authentication in the context of Qlik Sense?

Kerberos authentication is an authentication protocol that provides a secure method for verifying the identity of users and systems in a computer network. In the context of Qlik Sense, it is particularly significant because it enables single sign-on (SSO) capabilities, allowing users to access the Qlik Sense applications without repeatedly entering their credentials.

This protocol operates on a ticket-based system where users receive a ticket after an initial authentication process. This ticket is then used to access various services without needing to re-authenticate, enhancing both security and user experience.

The other options do not relate directly to the concept of Kerberos. For example, a security feature for data load or a firewall security measure does not encompass the broader role of Kerberos as an authentication mechanism. Similarly, while there are methods for data replication in environments utilizing Qlik Sense, these processes are not directly linked to the purpose of Kerberos, which specifically addresses authentication rather than data handling techniques or security measures for data loads.
