zt_wl_028 — Service Fabric cluster uses certificate thumbprint auth instead of Entra ID¶
Summary
Severity: High · Pillar: Workload · Chain role: ENABLER
Description¶
Service Fabric clusters with certificateThumbprint-based admin authentication rely on a long-lived certificate in the cluster's configuration. Rotation is painful, private-key extraction from any cluster node gives full admin. Modern Service Fabric supports 'azureActiveDirectory' authentication with group-based admin scoping — switch to it.
