zt_data_018 — Event Hub namespace does not use customer-managed key encryption¶
Summary
Severity: Medium · Pillar: Data · Chain role: AMPLIFIER
Description¶
Event Hub namespaces without customer-managed key encryption rely on Microsoft-managed keys, limiting tenant control over the encryption lifecycle. Using Key Vault-backed keys ensures the organization can rotate, revoke, and audit access to the encryption material.
