CNTR-K8-000160 - The Kubernetes Scheduler must use TLS 1.2, at a minimum, to protect the confidentiality of sensitive data during electronic dissemination.

Information

The Kubernetes Scheduler will prohibit the use of SSL and unauthorized versions of TLS protocols to properly secure communication.

The use of unsupported protocol exposes vulnerabilities to the Kubernetes by rogue traffic interceptions, man-in-the-middle attacks, and impersonation of users or services from the container platform runtime, registry, and keystore. To enable the minimum version of TLS to be used by the Kubernetes API Server, the setting 'tls-min-version' must be set.

Solution

Edit the Kubernetes Scheduler manifest file in the /etc/kubernetes/manifests directory on the Kubernetes Master Node. Set the value of '--tls-min-version' to 'VersionTLS12' or higher.
