01

Detect

ZopNight checks this automatically across Azure, with read-only access to the account.

02

Explain

Every finding says exactly what to change: Enable diagnostic logging on the AKS cluster.

03

Fix

The finding opens with the fix already written out, step by step, so it is one ticket, not an investigation.

Applies to
AKS Clusters on Azure
The fix, by hand
  1. AKS → the resource → Monitoring → Diagnostic settings → Add diagnostic setting.
  2. Enable category groups: kube-apiserver, kube-audit (or kube-audit-admin for lower volume), kube-controller-manager, kube-scheduler, cluster-autoscaler.
  3. Send to a Log Analytics workspace (preferred for KQL) and optionally archive to a Storage Account for long-term retention.
  4. Save; AKS streams control-plane logs within ~5 minutes.
  5. In Log Analytics, validate by running AzureDiagnostics | where Category startswith "kube-" | take 10.
  6. Set a Monitor alert on suspicious audit verbs (e.g. exec into kube-system pods) once you have a baseline.

These are the steps the finding carries in the product.

Category
Compliance. Configuration drift from best practice: public access, missing MFA, unencrypted storage, deprecated runtimes.
