To protect sensitive data in Apache Superset while allowing users to visualize relevant metrics, follow these steps:
1. Implement role-based access control (RBAC) by creating user roles with specific permissions and assigning them to appropriate users.
2. Utilize data source filters to restrict the data available for visualization based on user roles or attributes.
3. Use row-level security (RLS) to limit the rows of data accessible by each user, ensuring they only see information relevant to their role.
4. Enable database schema isolation, so users can only access schemas they have been granted permission to view.
5. Regularly audit user activity and access logs to identify potential unauthorized access or misuse of data.
6. Keep Superset updated with the latest security patches and best practices to minimize vulnerabilities.
7. Train users on responsible data handling and establish a clear data governance policy.
