name: User-Assigned Managed Identities for Azure Functions
author: princechaddha
severity: medium
description: |
Ensure that functions managed with Azure Function App are using user-assigned managed identities for fine-grained control over access permissions.
impact: |
Using default or system-assigned identities can limit the granularity of access control, potentially allowing broader than necessary access to resources.
remediation: |
Configure user-assigned managed identities for your Azure Function Apps to gain more granular control over permissions and reduce potential security risks.
