3.11 Verify that Docker server certificate file ownership is set to root:root

Information

Verify that the Docker server certificate file (the file that is passed alongwith '--
tlscert' parameter) is owned and group-owned by 'root'.The Docker server certificate file should be protected from any tampering. It is used to
authenticate Docker server based on the given server certificate. Hence, it must be owned
and group-owned by 'root' to maintain the integrity of the certificate.

Solution

chown root-root <path to Docker server certificate file>
This would set the ownership and group-ownership for the Docker server certificate file to
'root'.Impact-None.Default Value-By default, the ownership and group-ownership for Docker server certificate file is
correctly set to 'root'.
