Ensure that the --auto-tls argument is not set to true

HighLevel 1Manual reviewopenshift

Description

Do not use self-signed certificates for TLS. The benchmark marks this recommendation Manual.

How it is checked

Audit method: Manual review

This recommendation cannot be checked automatically. A scan lists it with these instructions when you pass --include-manual.

OpenShift configures etcd with secure communication. Openshift installs etcd as static pods on control plane nodes, and mounts the configuration files from /etc/etcd/ on the host. The etcd.conf file includes auto-tls configurations as referenced in /etc/etcd/etcd.conf. OpenShift 4 includes multiple CAs providing independent chains of trust, which ensure that a platform CA will never accidentally sign a certificate that can be used for the wrong purpose, increasing the security posture of the cluster.

How it is fixed

Fix method: Guidance or infrastructure patch

This setting is managed by the cluster etcd operator. No remediation required.
