In Splunk, which capability is essential for users to change authentication settings?

The capability that allows users to change authentication settings is crucial for ensuring that only authorized personnel can modify security and access controls within a Splunk environment. The capability specifically named 'change_authentication' is designed to grant the necessary permissions for modifying authentication settings. This includes configuring how users are authenticated, which is critical for maintaining the security posture of the Splunk instance.

While other capabilities might pertain to user management and editing permissions, they do not specifically encompass the action of changing authentication settings. This specificity is what makes 'change_authentication' the appropriate choice for this scenario, as it is tailored for that precise administrative function. The focus of this capability ensures that only users with the correct authority can execute changes related to authentication mechanisms, such as switching between different authentication methods or configuring integration with identity providers.
