# 1.1.6 Ensure that the scheduler pod specification file ownership is set to root:root (Automated)

## Profile Applicability

- Level 1 - Master Node

## Description

Ensure that the scheduler pod specification file ownership is set to `root:root`.

## Rationale

The scheduler pod specification file controls various parameters that set the behavior of the `kube-scheduler` service in the master node. You should set its file ownership to maintain the integrity of the file. The file should be owned by `root:root`.

## Impact

None

## Audit

Run the below command (based on the file location on your system) on the Control Plane node. For example,

```bash
stat -c %U:%G /etc/kubernetes/manifests/kube-scheduler.yaml
```

Verify that the ownership is set to `root:root`.

## Remediation

Run the below command (based on the file location on your system) on the Control Plane node. For example,

```bash
chown root:root /etc/kubernetes/manifests/kube-scheduler.yaml
```

## Default Value

By default, `kube-scheduler.yaml` file ownership is set to `root:root`.
