Control:

Set up the docker integration.

Description

You should verify that the /etc/docker directory permissions are correctly set to 755 or more restrictively.

Rationale

The /etc/docker directory contains certificates and keys in addition to various sensitive files. It should therefore only be writeable by root to ensure that it can not be modified by a less privileged user.

Audit

You should execute the command below to verify that the directory has permissions of 755+:

stat -c %a /etc/docker

Remediation

Run the following command: chmod 755 /etc/docker

This sets the permissions for the directory to 755.

Impact

None

Default value

By default, the permissions for this directory are set to 755.
