Ensure that the etcd data directory permissions are set to 700 or more restrictive

HighLevel 1Manual reviewopenshift

Description

Ensure that the etcd data directory has permissions of 700 or more restrictive. 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.

In OpenShift 4, etcd members are deployed on the master nodes as static pods. The pod specification file is created on control plane nodes at /etc/kubernetes/manifests/etcd-member.yaml. The etcd database is stored on the container host in /var/lib/etcd and mounted to the etcd-member container via the host path mount data-dir with the same filesystem path (/var/lib/etcd). The permissions for this directory on the container host is 700. Starting with OCP 4.4, etcd is managed by the cluster-etcd-operator. The etcd operator will help to automate restoration of master nodes.

How it is fixed

Fix method: Guidance or infrastructure patch

No remediation required. File permissions are managed by the etcd operator.
