You should verify that the /etc/sysconfig/docker file individual ownership and group ownership is correctly set to root.
Rationale
The /etc/sysconfig/docker file contains sensitive parameters that may alter the behavior of the Docker daemon. It should therefore be individually owned and group owned by root to ensure that it is not modified by less privileged users.
Audit
Verify that the /etc/sysconfig/docker file is individually owned and group-owned by root by running:
stat -c %U:%G /etc/sysconfig/docker | grep -v root:root
The command should return no results.
Run the following command: chown root:root /etc/sysconfig/docker
This sets the ownership and group ownership for the file to root.
Impact
None
Default value
This file may not be present on the system, and in this case, this recommendation is not applicable.
