Control: 3.12 Ensure that the Docker server certificate file permissions are set to 444 or more restrictively
Description
You should verify that the Docker server certificate file (the file that is passed along with
the --tlscert parameter) has permissions of 444 or more restrictive permissions.
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 should therefore
have permissions of 444 to prevent its modification.
Remediation
The following command could be executed:
chmod 444 <path to Docker server certificate file>
This sets the file permissions of the Docker server certificate file to 444.
Default Value
By default, the permissions for the Docker server certificate file might not be 444. The
default file permissions are governed by the operating system or user specific umask
values.
Usage
Run the control in your terminal:
powerpipe control run docker_compliance.control.cis_v160_3_12Snapshot and share results via Turbot Pipes:
powerpipe loginpowerpipe control run docker_compliance.control.cis_v160_3_12 --shareSQL
