Azure security baseline for Azure Route Server

This security baseline applies guidance from the Microsoft cloud security benchmark version 1.0 to Azure Route Server. The Microsoft cloud security benchmark provides recommendations on how you can secure your cloud solutions on Azure. The content is grouped by the security controls defined by the Microsoft cloud security benchmark and the related guidance applicable to Azure Route Server.

You can monitor this security baseline and its recommendations using Microsoft Defender for Cloud. Azure Policy definitions will be listed in the Regulatory Compliance section of the Microsoft Defender for Cloud portal page.

When a feature has relevant Azure Policy Definitions, they are listed in this baseline to help you measure compliance with the Microsoft cloud security benchmark controls and recommendations. Some recommendations may require a paid Microsoft Defender plan to enable certain security scenarios.

Note

Features not applicable to Azure Route Server have been excluded.

Security profile

The security profile summarizes high-impact behaviors of Azure Route Server, which may result in increased security considerations.

Supported Enabled By Default Configuration Responsibility
True False Customer

Configuration Guidance: Use network security groups (NSG) to restrict or monitor traffic by port, protocol, source IP address, or destination IP address. Create NSG rules to restrict your service's open ports (such as preventing management ports from being accessed from untrusted networks). Be aware that by default, NSGs deny all inbound traffic but allow traffic from virtual network and Azure Load Balancers.

Note: Customers cannot configure a UDR with a default route on the RouteServerSubnet. This is consistent with other hybrid-gateway services; and documented publicly for customers.
