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


You should verify that the Docker server certificate file (the file that is passed along with the --tlscert parameter) is individual owned and group owned by root.

The Docker server certificate file should be protected from any tampering. It is used to authenticate the Docker server based on the given server certificate. It must therefore be individually owned and group owned by root to prevent modification by less privileged users.


The following command could be executed:

chown root:root <path to Docker server certificate file>

This sets the individual ownership and group ownership for the Docker server certificate file to root.

Default Value

By default, the ownership and group-ownership for Docker server certificate file is correctly set to root.


Run the control in your terminal:
