Description

You should verify that the /etc/docker directory ownership and group ownership is correctly set to root.

Rationale

The /etc/docker directory contains certificates and keys in addition to various other sensitive files. It should therefore be individual owned and group owned by root in order to ensure that it can not be modified by less privileged users.

Audit

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

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

This command does not return any data.

Remediation

To resolve this issue, run the following command: chown root:root /etc/docker

This sets the ownership and group ownership for the directory to root.

Impact

None

Default value

By default, the ownership and group ownership for this directory is correctly set to root.
