# Change namespace privileges via unshare

### Event Information

#### Meaning

* This event indicates that a process attempted to change its namespace privileges using the unshare system call in the Kubernetes cluster.
* It could potentially be a security concern as it may allow a process to gain elevated privileges or escape from container isolation.
* To investigate further, you can list all the processes running in the cluster namespace using the following kubectl command:
  `kubectl get pods --all-namespaces`

#### Remediation

* Create a new ServiceAccount with restricted permissions in the target namespace:

```yaml theme={null}
apiVersion: v1
kind: ServiceAccount
metadata:
  name: restricted-sa
  namespace: <target_namespace>
```

* Bind the ServiceAccount to a Role with limited privileges:

```yaml theme={null}
apiVersion: rbac.authorization.k8s.io/v1
kind: Role
metadata:
  name: restricted-role
  namespace: <target_namespace>
rules:
- apiGroups: [""]
  resources: ["pods"]
  verbs: ["get", "list"]
```

* Finally, bind the Role to the ServiceAccount:

```yaml theme={null}
apiVersion: rbac.authorization.k8s.io/v1
kind: RoleBinding
metadata:
  name: restricted-rolebinding
  namespace: <target_namespace>
subjects:
- kind: ServiceAccount
  name: restricted-sa
  namespace: <target_namespace>
roleRef:
  kind: Role
  name: restricted-role
  apiGroup: rbac.authorization.k8s.io
```
