Information
Verify that the 'daemon.json' file permissions are correctly set to '644'or more restrictive.
Rationale:
'daemon.json' 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/docker/daemon.json
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.
