How do you control access to sensitive data in Splunk ES?

Controlling access to sensitive data in Splunk Enterprise Security (ES) is primarily achieved through the implementation of role-based access controls and permissions. This approach allows administrators to define roles and assign specific capabilities and permissions based on the needs of different users or groups within the organization.

By configuring roles, you can specify what data and functionalities each role can access, ensuring that sensitive data is only visible to those who require it for their work duties. This includes setting permissions for viewing, editing, or sharing data. Role-based access controls help maintain data security by minimizing exposure to sensitive information and ensuring compliance with regulatory or organizational policies.

While encrypting data at rest is crucial for protecting data integrity and confidentiality, it does not directly control user access or who can view the sensitive information once they are authenticated. Similarly, limiting the size of data logs and regularly changing user passwords are good practices for data management and security; however, they do not specifically restrict access to sensitive data itself in the way that role-based access controls do.
