The principle of least privilege (PoLP) is a defensive strategy that ensures users can only access the systems, processes, networks, and files required to complete their assigned tasks. This helps safeguard against unauthorized actions and maintain efficient operational performance. Kubernetes uses role-based access control (RBAC) to implement PoLP by defining permissions for individual roles within a cluster. By creating and binding roles, teams can restrict access to specific resources while ensuring only authorized users can perform necessary functions. RBAC helps align with PoLP by limiting exposure to potential bad actors without impeding job functions. Kubernetes provides an extensive native RBAC mechanism that enables configuration of permissions based on user roles, allowing teams to secure their cluster and containerized applications.
