Enforce the use of trusted registries using TLS

HighLevel 1Automatedopenshift-virt

Description

Transport Layer Security (TLS) is a cryptographic protocol used in this context to protect data in transit. Restricting operations to the use of trusted registries ensures the use of approved container images. Audit: Passes when .spec.storageImport.insecureRegistries of the HyperConverged resource is empty. Requires oc logged in to the cluster with read access.

How it is checked

Audit method: Shell command

shell

command -v oc >/dev/null 2>&1 || exit 1; v=$(oc get hyperconverged kubevirt-hyperconverged -n openshift-cnv -o jsonpath='{.spec.storageImport.insecureRegistries}') || exit 1; [ -z "$v" ] && echo compliant || echo noncompliant

Expected output: compliant

How it is fixed

Fix method: Guidance or infrastructure patch

Do not allow connections to insecure registries from hyperconverged resources. The cluster administrator can remove any insecure registry: $ oc patch hyperconverged kubevirt-hyperconverged - n openshift - cnv --type='json' -p='[ {"op": "remove", "path": "/spec/storageImport/insecureRegistries"}, ]'
