Ensure 'Authentication type' is set to 'Azure Active Directory' only for Azure VPN Gateway point-to-site configuration

Description

Enable only 'Azure Active Directory' (Microsoft Entra ID) authentication for Azure VPN Gateway point-to-site connections.

Rationale

Microsoft Entra ID authentication provides strong security and centralized identity management, and reduces risks associated with static credentials and certificate management.

Impact

Azure VPN Gateways incur hourly charges, with additional costs for point-to-site connections and data transfer. Pricing varies by SKU and usage. Refer to https://azure.microsoft.com/en-us/pricing/details/vpn-gateway/ for details.

Audit Procedure

Using Azure Portal

Go to Virtual network gateways.
Under VPN gateway, click VPN gateways.
Click the name of a VPN gateway.
Under Settings, click Point-to-site configuration.
Ensure Authentication type is set to Azure Active Directory only.
Repeat steps 1-5 for each VPN gateway.

Using Azure Policy

Policy ID: 21a6bc25-125e-4d13-b82d-2e19b7208ab7 - Name: 'VPN gateways should use only Azure Active Directory (Azure AD) authentication for point-to-site users'

Expected Result

All Azure VPN Gateway point-to-site configurations should have Authentication type set to Azure Active Directory only, with no other authentication methods (Azure certificate, RADIUS) enabled.

Remediation

Remediate from Azure Portal

Go to Virtual network gateways.
Under VPN gateway, click VPN gateways.
Click the name of a VPN gateway.
Under Settings, click Point-to-site configuration.
Ensure Authentication type click to expand the drop-down menu.
Check the box next to Azure Active Directory, and uncheck the boxes next to Azure certificate and RADIUS authentication.
Provide a Tenant, Audience, and Issuer for the Azure Active Directory configuration.
Click Save.
Repeat steps 1-8 for each VPN gateway requiring remediation.

Default Value

'Authentication type' is selected during creation of point-to-site configuration.
