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.

Impact

None.

You should execute the command below to verify that the directory has permissions of 755 or more restrictive ones:

stat -c %a /etc/docker

Remediation

You should run the following command:

chmod 755 /etc/docker

This sets the permissions for the directory to 755.

Default Value
