Discussion

Verify that the /etc/docker directory permissions are correctly set to 755 or more restrictive. /etc/docker directory contains certificates and keys in addition to various sensitive files. Hence, it should only be writable by root to maintain the integrity of the directory. By default, the permissions for this directory are correctly set to 755.

Check Content

Execute the below command to verify that the directory has permissions of 755 or more restrictive:

stat -c %a /etc/docker

If the permissions are not set to 755, this is a finding.

Fix Text

set the permissions for the directory to 755.

Execute the following command:
chmod 755 /etc/docker
