Control your role! Kubernetes RBAC explored

Kubernetes Role-Based Access Control (RBAC) is a robust built-in implementation that allows defining custom roles and assigning them to users, providing an important first line of defense against overprivileged user accounts. It's simpler to configure and maintain compared to Attribute-Based Access Control (ABAC), which is now considered deprecated. The Kubernetes RBAC implementation revolves around four main object types: Roles, RoleBindings, ClusterRoles, and ClusterRoleBindings. To use RBAC, you need to create a service account, bind roles to it, and switch to the corresponding kubectl context. This allows users and applications to authenticate and receive the correct permissions. Pairing RBAC with other Kubernetes security best practices is essential for maintaining a fully hardened environment.
