TMA-OPENSHIFT-2.7
Ensure that a unique Certificate Authority is used for etcd
Descrição
Use a different certificate authority for etcd from the one used for Kubernetes. The benchmark marks this recommendation Manual.
Como é verificado
Método de auditoria: Revisão manual
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. OpenShift uses a separate CA for etcd. These internal self-signing CAs enable automation because the key is known to the cluster. The certificates generated by each CA are used to identify a particular OpenShift platform component to another OpenShift platform component.
Como é corrigido
Método de correção: Orientação ou patch de infraestrutura
None required. Certificates for etcd are managed by the OpenShift cluster etcd operator.
