# Ensure that the /etc/sysconfig/docker file ownership is set to root:root (Manual)

## Profile Applicability

- Level 2 - Docker - Linux

## Description

You should verify that the `/etc/sysconfig/docker` file individual ownership and group ownership is correctly set to `root`.

## Rationale

The `/etc/sysconfig/docker` file contains sensitive parameters that may alter the behavior of the Docker daemon. It should therefore be individually owned and group owned by `root` to ensure that it is not modified by less privileged users.

## Impact

None.

## Audit Procedure

You should execute the command below to verify that the file is individually owned and group owned by `root`:

```bash
stat -c %U:%G /etc/sysconfig/docker | grep -v root:root
```

The command above should return no results.

## Remediation

You should execute the following command:

```bash
chown root:root /etc/sysconfig/docker
```

This sets the ownership and group ownership for the file to `root`.

## Default Value

This file may not be present on the system, and in this case, this recommendation is not applicable.
