Pull request overview
This pull request adds a new security assessment test (Test-Assessment.25535) that validates whether outbound traffic from VNET integrated workloads is properly routed through Azure Firewall. The test uses the Azure REST API to enumerate Azure Firewalls and network interfaces across all subscriptions, checks effective route tables, and verifies that default routes point to firewall private IP addresses.
Changes:
- Added a new PowerShell test script that asynchronously collects effective route tables from network interfaces and validates routing through Azure Firewall
- Added documentation explaining the security rationale and remediation steps for routing traffic through Azure Firewall
