Control: 3.10 Ensure that TLS CA certificate file permissions are set to 444 or more restrictively
Description
You should verify that the TLS CA certificate file (the file that is passed along with the --
tlscacert parameter) has permissions of 444 or is set more restrictively
The TLS CA certificate file should be protected from any tampering. It is used to
authenticate the Docker server based on a given CA certificate. It must therefore have
permissions of 444, or more restrictive permissions to ensure that the file cannot be
modified by a less privileged user.
Remediation
The following command could be executed:
chmod 444 <path to TLS CA certificate file>
This sets the file permissions on the TLS CA file to 444.
Default Value
By default, the permissions for the TLS CA 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_10Snapshot and share results via Turbot Pipes:
powerpipe loginpowerpipe control run docker_compliance.control.cis_v160_3_10 --shareSQL
This control uses a named query:
