Control: 3.14 Ensure that the Docker server certificate key file permissions are set to 400
Description
You should verify that the Docker server certificate key file (the file that is passed along
with the --tlskey parameter) has permissions of 400.
The Docker server certificate key file should be protected from any tampering or
unneeded reads. It holds the private key for the Docker server certificate. It must
therefore have permissions of 400 to ensure that the certificate key file is not modified.
Remediation
The following command could be executed:
chmod 400 <path to Docker server certificate key file>
This sets the Docker server certificate key file permissions to 400.
Default Value
By default, the permissions for the Docker server certificate key file might not be 400.
The default file permissions are governed by the operating system or user specific umask values.
Usage

powerpipe control run docker_compliance.control.cis_v160_3_14Snapshot and share results via Turbot Pipes:
