/etc/default/docker file permissions are set to 644 or more restrictively

docker

Classification:

compliance

Framework:

Control:

Overview

Description

You should verify that the /etc/default/docker file permissions are correctly set to 644 or more restrictively.

Rationale

The /etc/default/docker file contains sensitive parameters that may alter the behavior of the Docker daemon. It should therefore be writeable only by root in order to ensure that it is not modified by less privileged users.

Audit

Verify that the /etc/default/docker file permissions are set to 644 or more restrictively, by running:

stat -c %a /etc/default/docker

Remediation

Run the following command: chmod 644 /etc/default/docker

This sets the file permissions for this file to 644.

Impact

None

Default Value

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