Details

Verify that the ‘/etc/default/docker’ file permissions are correctly set to ‘644’or more restrictive.

Rationale:

‘/etc/default/docker’ file contains sensitive parameters that may alter the behavior of docker daemon. Hence, it should be writable only by ‘root’ to maintain the integrity of the file.

Solution

chmod 644 /etc/default/docker

This would set the file permissions for this file to ‘644’.

Impact:

None.

Default Value:

This file may not be present on the system. In that case, this recommendation is not applicable.
