name: System-Assigned Managed Identities for Azure Functions
author: princechaddha
severity: medium
description: |
Ensure that functions managed with Azure Function App are using system-assigned managed identities in order to allow secure application access to other Microsoft Azure cloud resources such as SQL databases, storage accounts, and key vaults. Using system-assigned managed identities minimizes risks, simplifies management, and maintains compliance with evolving Azure cloud services.
impact: |
Not using system-assigned managed identities may expose Azure Function Apps to security risks and compliance issues, complicating resource access management.
remediation: |
Enable system-assigned managed identities for your Azure Function Apps to enhance security and simplify the management of resource access.
