Why every change to a Microsoft Entra extension must be treated as suspicious by default

A technical deep-dive published on DEV Community outlines a strict monitoring framework for Microsoft Entra extensions, arguing that the default security posture for most Azure workloads is inappropriate for these components. The author contends that once an Entra extension reaches production, every configuration or code change should be considered suspicious until proven otherwise, rather than simply flagged for review. This inverted default is justified by the broad RBAC inheritance chains in Azure, which can allow contributors high up the management hierarchy to silently alter Function App code. The article identifies three distinct change surfaces — compute, identity credentials, and workflow definitions — each requiring its own diagnostic controls, dedicated alerts, and a defined response SLA. Teams that cannot confirm a change was pre-approved within that SLA are expected to treat the event as a security incident and initiate a rollback.
