In Kubernetes, access rights management is implemented through the following mechanisms:

RBAC (Role-Based Access Control) — the main and most flexible method. It allows creating roles with a set of permissions and binding them to users or service accounts via RoleBinding or ClusterRoleBinding.
ABAC (Attribute-Based Access Control) — an older method based on policies describing attributes of subjects and objects. Less common.
Webhook Token Authentication — external authentication and authorization service.
Service Accounts — special accounts for pods, which can be assigned roles.

Example of creating a role and binding:

apiVersion: rbac.authorization.k8s.io/v1
kind: Role
metadata:
  namespace: default
  name: pod-reader
rules:
- apiGroups: [""]
  resources: ["pods"]
  verbs: ["get", "watch", "list"]
---
apiVersion: rbac.authorization.k8s.io/v1
kind: RoleBinding
metadata:
  name: read-pods
  namespace: default
subjects:
- kind: User
  name: jane
  apiGroup: rbac.authorization.k8s.io
roleRef:
  kind: Role
  name: pod-reader
  apiGroup: rbac.authorization.k8s.io

Thus, you can flexibly manage user and service access to Kubernetes resources.
