Information

Creating namespaces for user-managed resources is important when implementing Role-Based Access Controls (RBAC). RBAC allows for the authorization of users and helps support proper API server permissions separation and network micro segmentation. If user-managed resources are placed within the default namespaces, it becomes impossible to implement policies for RBAC permission, service account usage, network policies, and more.

NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.

Solution

Move any user-managed resources from the default, kube-public, and kube-node-lease namespaces to user namespaces.
