CIS Red Hat OpenShift Container Platform Benchmark v1.7.0 - Control 1.2.31

Name: cis-ocp-v170-1.2.31
Author: CyberStrikeus

Profile Applicability

Level: 1

Description

Where etcd encryption is used, appropriate providers should be configured.

Rationale

Where etcd encryption is used, it is important to ensure that the appropriate set of encryption providers is used. Currently, the aescbc, kms and secretbox are likely to be appropriate options.

Impact

When you enable etcd encryption, the following OpenShift API server and Kubernetes API server resources are encrypted:

Secrets
ConfigMaps
Routes
OAuth access tokens
OAuth authorize tokens

When you enable etcd encryption, encryption keys are created. These keys are rotated on a weekly basis. You must have these keys in order to restore from an etcd backup.

Audit Procedure

OpenShift supports encryption of data at rest of etcd datastore, but it is up to the customer to configure. The aescbc cipher had been the only supported cipher up to OCP 4.13. Starting with OCP 4.13, the aescgm cipher can be used as well. No other ciphers are supported. Keys are stored on the filesystem of the master and automatically rotated.

Run the following command to review the Encrypted status condition for the OpenShift API server to verify that its resources were successfully encrypted:

# encrypt the etcd datastore
oc get openshiftapiserver -o=jsonpath='{range .items[0].status.conditions[?(@.type=="Encrypted")]}{.reason}{"\n"}{.message}{"\n"}'

The output shows EncryptionCompleted upon successful encryption.

EncryptionCompleted
All resources encrypted: routes.route.openshift.io, oauthaccesstokens.oauth.openshift.io, oauthauthorizetokens.oauth.openshift.io

If the output shows EncryptionInProgress, this means that encryption is still in progress. Wait a few minutes and try again.

Remediation

Follow the OpenShift documentation for encrypting etcd data.

Default Value

By default, no encryption provider is set.
