+#### Azure DDoS Protection
+
+[Azure DDoS Protection](../../ddos-protection/ddos-protection-overview.md), combined with application design best practices, offers enhanced features to defend against DDoS attacks. It is automatically tuned to protect your specific Azure resources in a virtual network. Enabling protection is simple on any new or existing virtual network and requires no changes to your applications or resources.

+Azure DDoS Protection offers two tiers: DDoS Network Protection and DDoS IP Protection.
+
+* DDoS Network Protection  provides enhanced features to defend against Distributed Denial of Service (DDoS) attacks. It operates at network layers 3 and 4 and includes advanced features such as DDoS rapid response support, cost protection, and discounts on Web Application Firewall (WAF).
+
+* DDoS IP Protection follows a pay-per-protected IP model. It includes the same core engineering features as DDoS Network Protection but does not offer the additional services like DDoS rapid response support, cost protection, and WAF discounts.

 #### Route Control and Forced Tunneling
 
 The ability to control routing behavior on your Azure Virtual Networks is a critical network security and access control capability. For example, if you want to make sure that all traffic to and from your Azure Virtual Network goes through that virtual security appliance, you need to be able to control and customize routing behavior. You can do this by configuring User-Defined Routes in Azure.
