The /etc/default/docker file permissions should be set to 644 or stricter
Set up the docker integration.
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
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.
