HighLevel 1Manual reviewopenshift

Description

etcd should be configured for peer authentication. 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 uses X.509 certificates to provide secure communication to etcd. OpenShift generates these files and sets the arguments appropriately. etcd certificates are used for encrypted communication between etcd member peers, as well as encrypted client traffic. Peer certificates are generated and used for communication between etcd members. 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 peer-client-cert-auth configurations as referenced in /etc/etcd/etcd.conf.

How it is fixed
