How can access to sensitive fields be controlled in Splunk?

Access to sensitive fields in Splunk can be effectively controlled through role-based permissions and field-level security. This approach allows an organization to define specific roles that users can have, each with custom permissions that dictate what data and features they can access within Splunk. By assigning roles, administrators ensure that only authorized users can view or interact with sensitive fields, thereby safeguarding sensitive information.

Field-level security adds another layer of protection by allowing the specification of which fields are visible to which user roles. This granularity helps to enforce data privacy and compliance with regulations, as sensitive information can be restricted to only those users who absolutely need access to it.

The other options do not provide a robust method for controlling access to sensitive fields, as they either advocate for less security (public access), suggest impractical solutions (password protection on individual fields), or recommend completely hiding fields from all users, which does not allow for controlled access where appropriate. Therefore, the combination of role-based permissions and field-level security is the most effective method for managing sensitive field access in Splunk.
