What method can be used to restrict user access in Splunk?

Role-based access control (RBAC) and permissions settings are key features in Splunk that allow administrators to manage user access efficiently and securely. By implementing RBAC, administrators can assign users to specific roles that determine what data they can access and what actions they can perform within Splunk, such as creating, editing, or deleting saved searches and dashboards. This system sets clear boundaries for what users can see and interact with, ensuring that sensitive data is protected and that users only have access to the resources pertinent to their work.

In addition, Splunk allows the specification of permissions at various levels, including per app and per index, giving administrators granular control over user access. This ensures that only authorized users can view or manipulate specific sets of data or functionalities, aligning with best practices for data governance and compliance.

While manual configuration of user profiles could provide some level of access management, it lacks the systematic and scalable approach that RBAC offers, especially in environments with many users. System-wide password changes and data encryption methods contribute to security but do not directly control user access in the way that RBAC and permissions settings do.
