What is the main goal of using role-based access control in Splunk?

The main goal of using role-based access control (RBAC) in Splunk is to define user capabilities and access levels. This mechanism allows administrators to assign specific roles to users, which in turn dictate what data users can access and what actions they can perform within the Splunk environment. By defining roles, organizations can ensure that users have the appropriate permissions based on their responsibilities and needs, thereby maintaining security and data integrity.

Role-based access control helps to prevent unauthorized access to sensitive data and applications in Splunk. It allows for a structured way to manage user permissions efficiently, ensuring that users can only view or manipulate the data for which they have appropriate rights. This is particularly important in enterprises where data permissions are essential for compliance and regulatory purposes.

The other options, while they address various aspects of system management, do not pertain directly to the primary objective of role-based access control. Limiting data storage capacity, increasing software performance, and allowing guest accounts do not align with the fundamental purpose of RBAC, which centers around managing user roles and permissions effectively to protect data access.
